"BASE MEMORY 640k EXTENDED MEMORY 2095104K TOTAL MEMORY 2096128K" Did you copy and paste that, or did you type that yourself? If that with one module installed, or both? 2gb is 2091752 kb (Binary size, which is what Windows and your bios uses.) Those latter two figures are impossible if your total ram installed is 2gb. However, you could get oddball results like that if you have more than one ram module installed and at least one is incompatible. Or - extremely unlikely - conceiveably, if you get a result like when your ram IS confirmed to be compatible, there may be bugs in the bios version, but I have never heard of that showing more ram than you have. ....... "no mem, no hdd installed got a very long BEEP 15 secs of so connected ide hdd 15sec long beep" That may be the normal beep "pattern" for your bios brand and version of it for no ram or a ram problem. "attached one ddr2 800 memory stick GOT ONE SHORT (1 SEC, IF THAT) short beep DISK BOOT FAILURE" If the bios completes the intial POST (Power On Self Test)sequence successfully, it is normal to hear one quick beep. If the hdd was not attached, and no other bootable item in the boot order in the bios Setup is detected, that message is normal. "attached hdd again one short beep but then got BSOD STOP: 0x0000007b......." 1 beep - the POST sequence completed successfuly. Your bios must have found the proper hard drive and the bootable partition Windows is on, and booted it. STOP error messages are generated by the operating system, not the motherboard, if you have Win 2000 or XP (or Vista?) installed on a hard drive and the bios successfully boots from the hard drive partition Windows is on. Look up the stop error on the web. E.g. for: STOP: 0x0000007b STOP: 0x0000007b ............INACCESSIBLE_BOOT_DEVICE. Advanced troubleshooting for "Stop 0x0000007B" errors in Windows XP http://support.microsoft.com/kb/324103 Etc. ..... Regarding your ram and ram timings.... "memory ppl says memory is compatible with single core 3.6 chip" It's the mboard's main chipset and its memory controller the ram has to be compatible with, unless the cpu has the memory controller built into the cpu in which case the ram has to be compatible with the cpu, but that is a very recent feature most cpus don't have. "note:- memory stick says on sticker "2GB PC 6300/6400 800MHZ DDR2 RAM WARRANTY VOID IF REMOVED" undernearth it says 667" "tested memory one went 100% the other not so good, so im not using that one." I assume you're only using the one that tested okay at the moment. Did you buy this ram new, for this build? I've never heard of any ram being rated PC6300. If it's rated for PC6400 800mz I have no idea why it would have 667 on it at all, unless that's a code for something else. It should run at PC6400 / 800mhz settings. Is there a brand name and an ID string as well? E.g. for Kingston ram the ID string usually starts with KVR. OR - is there info like that on the bill for the ram that tells you who made it, etc? If there isn't, it's generic ram, and it is difficult or impossible to look up whether it is listed as compatible with your mboard chipset, unless you bought it from some place on the web where you could look up ram that is compatible with your mboard model for sure (guaranteed to work in your mboard). However, even if you can't look it up, you could test it with a ram diagnostics program (memory test) - if it passes, it's fine - if it doesn't it's probably a hundred times more likely it's incompatible than it is actually bad. On the other hand, if new ram is actually bad, which is EXTREMELY unlikely, it is many times more likely that shows up right away or shortly after you have first installed it, rather than after it has been working fine for a long while. Ram that is not 100% compatible may test fine when installed by itself, yet fail the ram tests when more than one is installed. Don't mess with the ram timing sseetings unless you have the info about what the ram timing settings of your ram are. If the ram timing specs are not printed on the ram modules and you have no info about what they are, such as on the bill for the ram, try loading ordinary bios defaults or Safe defaults or similar in your bios Setup settings, rather than optimal defaults - that should set the bios to use more conservative ram timing settings that should work with any ram. Generic ram often has slower (at least some of the numbers are higher) ram timings. ....... "fully formatted 80 gb IDE HDD 100%" What do you mean by that? The same thing as this? "i installed formated hdd and installed xp on my other comp without my other mobo drivers and installed it to the biostar" Or was the drive just partitioned and formatted and had no data on it this time? "setup is copying files..... IT DONE 2% CRASHED!!!!!!!!!!!!!!!!!!!!!!!!!!! RESTARTED SAID "NTLDR IS MISSING" yeah i know, windows not installed" I'm assuming there is only one hard drive installed, not two. Was that before, or now? You cannot get that error if there is no data on the hard drive. Setup may make the partition Windows is on bootable right after it formats the drive, but if the first stage of Setup does not complete normally, Windows is probably not actually setup to boot into Windows properly. You must correct whatever is causing Setup to fail early. Try ram that IS listed as being compatible with this mboard. Try another optical drive if you have one.

hi tubesandwires thanx for getting back i hoped if anyone could figure it out it would be you, and reading from your comments looks like you are puzzled as much as me. its so frustating. i will look at it again today and see if i can get those numbers from the memory serial whatever and get back to ya. the thing im looking at now or havew been since i got this board is the board itself. ive read now theres 2 ppl who have had massive problems with getting this board to work. gettin back to the hdd, it was just one, ide, 80 gb and i formatted it with the full XP version disk, where it says do you want quick or full format, or leave file system intact. so i thought ok i scrub of windows what i put on there from my asrock mobo without the asrock drivers. it done that and then after it said it was copying windows files or the operating system to the hdd and it only done 2% (piece of crap) lol then when it restarted it was winging about NTLDR IS MISSING. that also happened on the 750gb sata 2 brand new drive i got for it. took 3 hours to format it and then for the same to happen i can tell you i wasnt happen if you know what i mean. i think its done to the mobo i really do Im hoping on sending this back and getting adifferent mobo thats not ASUS, i got this biostar board cause i liked the features (me no one else so if anyone has any bad comments about it do yourself a favour and keep it to yourself because it doesnt help anyone) unless of course you seriously had problems with it like me. right will be back later and thanx again tubesandwires for your comments they really do help m8

hello back again bit late but been busy decorating, and been testing this problem again for like an hour or more and here are the results. tried my other dvd drive, 100% works use it all the time, and it got to 30+ % of installing windows (i just wanted it too hurry up and crash than keep more hopes up) then it did crash!!!!!. loaded optimised defaults and same again with the installing but this time 2% DOUBLE CHECKED THOSE NUMBERS AND THEY ARE CORRECT BIOS BASE MEMORY 640K EXTENDED MEMORY 2095104K TOTAL MEMORY 2096128K the memory sticks i took very close look at them and it says underneath heat shields 2g667 UL 002EJCJ463 0611 samsung chips it says - K4T1G083QB-ZCE6 so what do you experts think the problem is, might be? in my last comment i said i did not want to get an asus board what i meant to say is i dont want to get another biostar board, i was thinking asus cause thats what i want to change it too. what can the problem be?............. the hdd is always the same wheather its an ide hdd obviously without SATA CABLES that does away with loose sata connectors, sata 2 drive, and sata 1. come on ppl must be someone out there who knows. can it be the chip it passed all tests i ran on it? two motherboards defective (possible?) so if i get a successful post beep, does that mean what ever hardware i have, i would be able to load xp or should i sasy INSTALL XP? this 2nd build of mine is enough to be my last. ok will check back later thanx again for everyones help.

ok just thought id add this bit, there was one comment above saying about does your motherboard bios spell device incorrectly and it does, decvie. anyway thought id check memory that is comatible dont know why but what else is there. ON MY BIOSTAR BOX IT SAYS DDR2 667, in the INSTRUCTIONS it says DD2 533/667 and here http://www.memoryx.net/biostar2gb40... it says DDR2 400 well now i am ******* LOST it doesnt say anything about ddr2 400 on the website for it, probably doesnt even take 2gb in each slot either think its been along day. no i take it back its this mobo doing my head in. if i won the euro lottery i would buy biostar and shut it down with immediate effect for supplying misleading information. hope i dont dream about biostar factories tonight i need some mental rest. signal lost (beep) Zzzzzz

"tried my other dvd drive, 100% works use it all the time, and it got to 30+ % of installing windows (i just wanted it too hurry up and crash than keep more hopes up) then it did crash!!!!!. loaded optimised defaults and same again with the installing but this time 2%" If the 30% happened with bios defaults or safe bios defaults, you probably need to tweak the ram timimgs a bit slower (higher numbers) than what they are when the bios is set to bios defaults or safe bios defaults. "DOUBLE CHECKED THOSE NUMBERS AND THEY ARE CORRECT BIOS BASE MEMORY 640K EXTENDED MEMORY 2095104K TOTAL MEMORY 2096128K" As I said before.... "2gb is 2091752 kb (Binary size, which is what Windows and your bios uses.) Those latter two figures are impossible if your total ram installed is 2gb. However, you could get oddball results like that if you have more than one ram module installed and at least one is incompatible. Or - extremely unlikely - conceiveably, if you get a result like when your ram IS confirmed to be compatible, there may be bugs in the bios version, but I have never heard of that showing more ram than you have." If you have only one module installed, there is definately something wrong with your bios version. ***************************************** DO NOT do the following if you want the option of being able to return the mboard. The warranty is void, and the mboard is yours forever, once you flash the bios yourself! If you don't want to do this, return the mboard and get a different one like you were thinking of doing! There are lots of AM2 mboards to choose from, and you can also use any AM2+ mboard with your cpu and ram! E.g. If you in the US and you want one with all the legacy ports and support for up to 4 IDE hard drives, if you don't mind it having a slightly older AMD chipset, you might be interested in the AD580XR here - I recommend it: www.epoxstore.com Don't worry about the 90 day warranty - in my experience Epox mboards last far longer than their original 3 year warranty. The manual and all drivers and other info are on the Taiwan Epox site for this model. It supports the 6000 and 6400 cpus as is. I you want more info I can tell you more. ****************************************** I usually DO NOT recommend you flash your bios, but in this case, you probably need to flash it to the newest version available, if the version you have is older. - make sure you get the bios update for your exact model and mboard version or revision - the later or, both - is printed directly on the mboard. - Find and follow the flash instructions. - If you have the choice of a bootable floppy method of flashing the bios, choose that instead of a Windows based method - that is the safest way to flash your bios. Even if you don't presently have a floppy drive connected, the mboard probably has a floppy data cable header yiou can connect to. - If you don't have a bootable floppy method to choose, if the mboard bios has the built in ability to flash the bios, use that rather than a Windows based method - see your mboard manual. I recommend you use Windows to check your floppy using FULL format. FULL format is slower, but will find and exclude from use any previously undetected bad sectors on a floppy, a common problem these days. In XP, RIGHT click on A: to find Format, DO NOT use the Quick format switch, format the floppy. After the format has finished, RIGHT click on A:, choose Properties - Free Space should be 1,457,664 bytes for an error free floppy. If it is less than that and the floppy is less than about 7 years old, I recommend you don't use it - it will probably get worse. Format another floppy instead. After you flash the bios, the first time you boot you will get a "Cmos Checksum Error...." or similar message. You will either be prompted to enter the bios Setup or you will automatically go there. Enter the bios Setup, set the date and time, and load Bios Defaults - save settings, reboot. You MUST do this (or Clear the CMOS by moving a jumper on the mboard) in order to make sure the bios update is fully accepted by the mboard's bios - otherwise, the contents of the Cmos part of the bios and what you see in the bios Setup may not match the bios version, and your settings in the bios Setup may not work properly. ............... "the memory sticks i took very close look at them and it says underneath heat shields 2g667 UL 002EJCJ463 0611 samsung chips it says - K4T1G083QB-ZCE6" That's not what I was hoping you would find - sounds like generic ram, but at least it has Samsung chips.

whats "generic ram" i would have thought it would mean unbranded, but then you say at least its got samsung chips on it. im confused, you said "sounds like generic ram" what bit is that theres not much else to look at other than the chips on it?....am i missing something so you think i could get this working if i tweak the memory timings? do i have to tweak the ADVANCED MEMORY TIMINGS AS WELL??... ived already tried 6.5.5.17 5.5.5.15 5.4.4.12 4.4.4.15 4.4.4.12 what bit do i have to change? 1st,2nd,3rd,4th column just athought but you seem to mention the bios ram numbers are not right base,ext,tot memory so maybe the ram is faulty after all i got it off fastmemoryman if that rings abell

The most glaring thing to me is those impossible numbers: EXTENDED MEMORY 2095104K TOTAL MEMORY 2096128K 2gb is 2091752 kb You have not said so specifically, but if you have only ram module installed the only thing I can think that could cause that is a bios version that is not working correctly. I have NEVER seen the bios find more ram that the amount installed before. If I were you I would return the mboard, tell them about that wrong count, and get something else. If you flash the bios, if that doesn't fix the problem, you cannot return the mboard, at least not without lying. ...... Generic ram is ram that does not have an obvious stuck on label with a brand name on it - if it doesn't have that it usually has no numbers/letters on it that you can use to look up to find out who made it either. I tried searching with that stuff you found on the ram modules, and pieces of them, and came up with absolutely nothing useful. Buying generic ram modules saves you a few bucks, but you usually can't look it up anywhere to make sure it is compatible. It can have any brand's individual chips on it. The fact that yours has Samsung chips is good, but the module was not made by Samsung. You can look up the specs of the individual chips but that tells you nothing about the way the chips are wired to the module. If you had a module actually made by Samsung, it would have Samsung on the stuck on label, and an ID string on the label like this: M378T5663RZ3-CF7 As far as the ram timing goes, I haven't messed with that, but I do know the higher the numbers, the slower the ram timing, the more likely it will work in any mboard. But you have no information to tell you what the ram timing is rated at.

thanx for replying so quickly tubesandwires you are a very busy person, and im very grateful i can tell you, what you said has gave me more knowledge which is good, the more you learn the less you have to ask questions. well another thing i didnt tell you (lol) is the other exactly same board i had brand new, that didnt work, i thought it was down to a cracked solder joint but before i sent it back i did FLASH the BIOS to the newest version successfully, ive done that on my asrock board as well. so not new to it. and it still didnt work!! The MEMORY i got of ebay i did ask shop i got the board from "WILL THIS MEMORY WORK and they said YES" i also to CONFIRM i asked the memory ppl and they said the SAME. i dont just get parts blindly and hope they fit together as one of the comments thought i do.(not from you though) the memory was sold as SAMSUNG MEMORY that was another reason i got it, being brand name and all i knew i couldnt go wrong, but what you told me about the sticker, and the pc6300 written on it had me puzzled but like i thought samsung memory "its good" So what do i do from here??... do i get an EXCHANGE FOR A DIFFERNENT mobo that accepts ddr2 800 without OC (cause oc is complicated) and then HOPE the memory will work OR do i send the memory back and get replacement of same or 667, not sure 667 would would with my single core 3.6 800fbs (would it) as i thought it would have to be ddr2 400 as it is half of the CPU FSB so the mobo is at fault or the memory is? thats the conclusion ive came to from what i have learnt from your comments. thanx again for helping me out im very grateful. jason

Assuming the one ram module DOES test fine IN THIS MBOARD, if I were you I would return this mboard and get something different! A lemon is a lemon is a lemon! " the other exactly same board i had brand new, that didnt work, i thought it was down to a cracked solder joint but before i sent it back i did FLASH the BIOS to the newest version ....and it still didnt work!!" The mboard warranty of any mboard is always void once you flash the bios yourself. You're fortunate that they gave you another one. Bad soldering or cracked solder joints is extremely rare these days - it's extremely unlikely that was the problem. If there was nothing actually physically or electronically wrong with that mboard, then if flashing the bios didn't cure the problem, if there is nothing wrong with the mboard or the ram, then it has to be it's the bios that's out of whack. Did you have both modules in the original mboard or just the one that tests okay? However, if you had only one module installed, that in any case does not account for the impossible figures you are quoting: "EXTENDED MEMORY 2095104K TOTAL MEMORY 2096128K" assuming you now have just one 2gb ram module installed - 2gb is 2091752 kb. That's another thing altogether. You have not answered this: DO YOU STILL HAVE ONLY ONE RAM MODULE INSTALLED? ...... You said in response 7: "memory stick says on sticker "2GB PC 6300/6400 800MHZ DDR2 RAM WARRANTY VOID IF REMOVED" undernearth it says 667"" and in the last post ""The MEMORY i got of ebay i did ask shop i got the board from "WILL THIS MEMORY WORK and they said YES" i also to CONFIRM i asked the memory ppl and they said the SAME." "the memory was sold as SAMSUNG MEMORY" It has Samsung individual chips, but according to what you have said is on the module labelling the module was NOT made by Samsung! You should NOT have to look under the heat spreader! If it was made by Samsung, it would have the proper label with the Samsung brand logo and an ID string Samsung uses! Like so: http://cgi.ebay.com/1GB-KIT-2X512MB... NOTE that it is a USED module pair. - Samsung used to make memory modules themselves, but for some time now they no longer make common types of new memory modules, including DDR2 memory modules. If you find any geniuine Samsung modules at all they are USED, or new but OLD STOCK! - "ON MY BIOSTAR BOX IT SAYS DDR2 667, in the INSTRUCTIONS it says DD2 533/667 and here http://www.memoryx.net/biostar2gb40... it says DDR2 400" It takes any of DDR2 400, 533, or 667 http://www.ec.kingston.com/ecom/con... Your mboard was never rated to use DDR 800 ram, and it still isn't - that cannot be upgraded because the mboard chipset does not support it. There is no way any vendor can say DDR 800 ram will work at 667 mhz for sure in your mboard, unless they have the detailed info about how the ram is organized and wired on the module - the latter must be compatible with your mboard. The average Ebay seller or ram vendor does not have that info. There are probably no lists of ram compatible with your mboard model anywhere on the web that include DDR2 800 modules. The DDR2 800 spec itself is backward compatible with the DRR2 667 specs, but there are other things involved that determine whether the module will be compatible with your mboard. However, according to what you have said the one module tests fine on this mboard. "tested memory one went 100% the other not so good, so im not using that one." I'm ASSUMING that's on this mboard. That result may be invalid if it wasn't! If that WAS on another mboard, test the ram on THIS mboard. If it fails the tests, then return the ram you bought if you can, and get ram that IS listed as compatible with your mboard. DO NOT rely on what a local or web based seller tells you. You need to go to memory module manufacturer's or major ram distributor's web site, where you can use your mboard model to look up which modules will work in your mboard for sure. If you can't do that for a specified module in a sellers ad or one you find locally, don't buy the ram! Once you know the ID string on the brand name modules that work for sure, you can search using that, or check out local places, that have that same module ID string, and buy it at whatever price you think is reasonable. e.g. www.kingston.com www.crucial.com www.corsair.com www.mushkin.com or for generic ram guaranteed to work for sure www.memorygiant.com etc., etc. "do i get an EXCHANGE FOR A DIFFERNENT mobo that accepts ddr2 800 without OC (cause oc is complicated)" Yes - get something else! There is NO WAY you would be able to overclock the ram on this mboard to run anywhere near 800mhz even if you wanted to!

hi tubesandwires very interesting read that you posted. em...i got the ddr2 800 memory as it says on the internet about the ddr2 800 e.g. Memory: 2x 240pin DDR2-800(OC)/667 DIMMs, Max Capacity 4GB http://www.ewiz.com/detail.php?name... yes i only have the one memory stick in i did say but what with writting tons i suppose its easier to miss it, anyway just the one memory stick and those figures are CORRECT i went back and double checked, yesterday before i posted that weblink you posted i found that last night after you mentioned "find memory that IS compatible, if only id came to that site first. do you think i should leave biostar alone? just that i saw a cracking biostar mobo and it says loads of compatible cpus including pentium 4 single core that i have but the processor number misses mine. mine is P4 3.6 Ghz SL7Z5 (((660))) P4 Processor 661 SL94V 3.60 GHz 800Mhz 86W p4 Processor 651 SL96J 3.40 GHz 800Mhz 86W P4 Processor 651 SL8WG 3.40 GHz 800Mhz 86W p4 Processor 651 SL94W 3.40 GHz 800Mhz 86W cant understand why my processor number isint on there? does that mean its not compatible? also with my cpu 3.6 with a fsb of 800 (200mhz think thats right) would i be able to get the ddr2 667 memory then for the biostar board would they work ok or not being as 667 would be running at 333 i think man you have patience, sorry if i sound abit you know, just trying to understand it all. thanx again m8

Again, if I were you I would not use this mboard. I would not take the chance of flashing the bios either, because as I said before, your mboard warranty goes out the window when you flash the bios yourself, and the seller is under no obligation to allow you to return it, or exchange it for another of the same. Your posts sometimes read like as if they are a mixture of older and newer info - hence why I wanted you to confirm you had only one module installed when you were getting those impossible memory amounts being reported. If you had two modules installed, I've seen that situation many times where the memory reported is a lot less than the ampount installed, but I have NEVER seen MORE memory reported than the amount actually installed. If that's the module that passed the memory tests on THIS mboard, there's nothing wrong with it. However I don't know if the memory test results depends direcly on the ram timing settings in the bios, or whether it somehow uses lesser settings. There is usually a setting in the bios where you can set the ram to "by SPD" or similar - in theory that should make the bios automatically find the right ram timing settings for the ram. The SPD info is on a very tiny chip on each ram module on one end of the module - the module maker is supposed to put essential data in that - however, sometimes with generic ram, not all of the needed info was put there. Some older mboards have some memory built into the mboard, as well as you can install it in ram slots, but that does not apply to more recent mboards including yours. Some older mboards have dedicated video memory for onboard video, but the total ram amount reported in the bios never includes that, and that does not apply to more recent mboards including yours as well. In any case I can think of no possible way that impossible reporting of the memory amounts would have anything to do with anything other that a bios version that has bugs in it. If I assume there was nothing actually wrong with the mboard you returned, obviuously flashing the bios did not cure your problem. Since you no longer have that mboard, there's no way of determining whether the total ram amount reported after you flashed was still the impossible amounts (unless you wrote it down somewhere). Your particular cpu not being listed is probably an ommision on their part. You could go to the Intel web site and look up what the difference between your SL7Z5 and the other SLxxx designations are, but if a cpu is not recognized by the bios properly, what usually happens is either the mboard does not boot at all, or it does boot but the cpu is set to lesser settings than it was designed to use because the bios doesn't know what to set the cpu to. Obviously your mboard is booting, and I have gotten no indication that it's not running at it's proper speed in your posts. Also, the cpu support list often mentions which bios version you must have to support all the cpus listed, or which bios version you must have in order to support a particular cpu. Most mboard makers such as Asus update the list when newer bios versions include support for more cpu types, but in some cases the mboard maker neglects to update the list, and it may be outdated, or even the cpu support list for the original bios version. If you bought the mboard new recently it probably has a newer bios version than that. The bus speed the cpu can use (bus speed x a multiplier = cpu speed; some cpus multiply the fsb bus speed on the cpu itself as well) can be different from the bus speed used for the ram - in this case the bus speed for the ram on this mboard is a max 333mhz (it's actually 333.333 etc. mhz - the 3's repeated forever) mhz, and the way the DDR2 ram works, in effect, on the module itself (DDR = Double Data Rate), doubles that to 666.666 etc. mhz (the 6's repeated forever) which is rounded to 667mhz. .......... If this is a bios programming problem can it be fixed? Probably, but unless you are prepared to find hard to find info about what to look for and how to correct it with your own self edited modified version of a manufacturer's bios version and flash your bios with that, your only choice that will work for sure is to get a bios upgrade (not update) from a vendor on the web, who has either a custom bios version that supports all possible features and cpu types that your main chipset and mboard can support, or a replacment bios chip that you can replace your bios chip with, if your bios chip is removable, that has that same maxxed out bios version on it, but that will cost you nearly as much as many new mboards.

Hi had flu all week so just catching up here, i see no resolution despite T&W large amount of effort , (sound suggestions btw), anyway went to the friends place yesterday who has the same mobo and: EXTENDED MEMORY 2095104K is correct his does the same, it adds up the 640k & the level 2 cache? ddr800 note the * in the manual, it runs overclocked with this memory configuration probably exceeding somthing in the hardware hence crashes, (not suprising for a £30 board). * it cant run in dual channel mode with two sticks of ram ddr800 , again due to being OC mode, dont know why it just states that. explains why my friends mobo came with one 2 gig stick of ram, his ram is generic also note biostar has recently deleted from its web page the previous bios only one now remains have you emailed them for some answers? & finally probably bulldozing my earlier assumption your cpu isnt in the vendors list may be for a reason. that chip is unusual may be a run out but i would suggest you change it for a intel core 2 duo, e6750 seems to work fine with 2gig 667 ram single stick ! if you have more cash to spend , if not its worth a look here in the budget section of asrock , it supports the prescot 660 and ddr800 http://www.asrock.com/mb/overview.a... good luck

1stepbeyond "EXTENDED MEMORY 2095104K is correct his does the same, it adds up the 640k & the level 2 cache?" The 640kb is supposed to be always part of the total ram, not in addition to it. Some bioses use 1mb as the total conventional memory amount, which is more realistic - that's the amount Windows cannot use itself, directly. The L2 cache amount is never supposed to included in the total ram amount. Even if you include the two amounts, it doesn't account for the difference between 2096128KB and 2091752KB for a true 2gb. Still sounds like a lemon bios to me.
