Specs: Windows XP, 1.9ghz/512 sdram
howdy guys :)

i have a pc chips m848a rev 2.1 mobo that does not see the athlon xp barton core at its normal value (333fsb). so i'm guessing it needs a bios update. help me find it please?

I always say it's best to doublecheck.

A bios update cannot increase the max fsb of the mboard or the mhz the cpu runs at if the main chipset is not capable of it. Look at the specs for the chipset - e.g. there should be more than enough info in the manual you can get on the PCChips web site for the model.

IF AND ONLY IF there is no limitation like that.......

Go to the PCChips web site and look up the cpus supported list, or similar, for the model. Often on such a list, it also says somewhere which particular bios version or above supports each cpu on the list, or which particular bios version supports all the cpus on the list. If the cpu you want to use is not in the list, either there is no support for the bios recognizing it, or there might be but they have not updated their info and there's no way of knowing for sure.
Also, there might be info about which cpus are supported by a bios update (or above) on the page where the bios update sare, but it's often vague.

If you can't find a manual or bios updates for it, there are other third party sources that have archived updates for and info about older PCHips mboards - let me know.
However, they often do not have any more than vague cpu support info, if any at all.


By the way, PCChips (Hsing Tech) has a reputation of using the absolute cheapest bios chips they can get - they are more likely to physically fail while flashing than those on other mboard brand models - they may fail the FIRST time you try to flash the bios - in any case, if you flash, do it as few times as you can.

It's Hsing Tech who actually makes the mboards - but they do not sell them as Hsing Tech brand models. They sell them retail under their own PCChips brand name, and they also sold/sell them to other vendors, many in the past, fewer these days, who may use the same or similar or very different model numbers for the same Hsing Tech / PCChips model - e.g. many cheaper ECS mboards were/are often actually made by Hsing Tech. If the mboard has no model number printed on it, only a Ver or Rev number, if the manual does not mention a brand name, if any chips on the mboard have a model number starting with HT, if it's got certain obvious odd ball labelling on a heatsink or elsewhere on the mboard that only Hsing Tech uses, it's actually a Hsing Tech mboard.

I just took a look at the PCChips web sites - they have downloads and info for m848a, but ONLY for Rev 5.0, on both the USA and global web sites.

Taiwan, English, global

USA, English

You cannot use the cpu support info for a newer Rev and be sure it applies to an older Rev.
You cannot use the bios updates for a newer Rev unless it says on the page where the bios updates are or in readme files or release notes for it that you can use the same bios updates on an older Rev.

In most cases, when the main Rev number changes, e.g. 2.x to 3.x, the I/O chip has been changed, or some other major chip has been changed, that requires different bios code to recognize it. If you use the wrong bios update, it is likely the mboard will not boot normally the next time you boot after you flash the bios, if it doesn't just plain refuse to flash the bios when you attempt to.

I looked at many of my third party sources for PCChips mboard info and downloads - they either have nothing for 8xx series mboards, or many are now dead links, so I haven't found anything from those sources.

You may be out of luck.
You could tryt searching for: bios update m848a rev. 2.1 or similar (or 848a) on the web, but you may not find anything, or any info about what cpus that rev or the bios update supports.
Regarding the max fsb speed and mhz cpu connected to it can support, any mboard that has the same two main chipset chips would have the right info in the specs or the manual for it, but usually one of the two has a heatsink on it.
If the one that does not have a heatsink has a model beginning with HT on it, it was renamed by the manufacturer when it was made to what Hsing Tech wanted to name it - what it actually is can be looked up on the web.

However, there's one thing you could try, if you do have another cpu that works in the mboard. Since it's quite possible the same mboard model was also sold by another vendor, if you can supply the bios string you see when you boot the computer, or if you can use Bios Agent, I may be able to find another brand's identical model that has info I can point you to, and possibly bios updates for it - when it's a Hsing Tech mboard, the vendor's bios updates are usually identical to the Hsing Tech / PCChips updates.

The bios string is usually a long string of numbers/letters at the bottom of the first black screen as you boot your computer - it often begins with a date - usually you can press the Pause key to read it and copy it down, and press any key but Pause to continue booting.

If you also have a hard drive with Windows installed on it on the mboard...
Go here, download BIOS AGENT.
Run BIOS AGENT to find your bios string.
- here's the link that downloads Bios Agent

The current Bios Agent calls the bios string the Bios ID.
Tell us the Bios ID it finds, or everything Bios Agent finds, and include any dashes, etc.

Bios Agent must be used in Windows.

If you do have other socket A cpus but have not tried them, your mboard should support most socket A cpus that use 266mhz or less, including the older Athlon pre-XP cpus; it may not support an XP2600 266mhz, which were and are relatively rare to find used (most you find on the web are XP2600 333mhz; Barton core); it may not support anything above XP2600.

There is another option if you're not opposed to spending some bucks.
Search for a bios UPGRADE (not a bios update) for it. There are vendors on the web that make modern bios upgrades for older mboards that will support all the possible settings and cpu types your main chipset will support - that often goes beyond what the newest mboard manufacturer's bios update supports - and you should be able to contact them to ask if the cpu you want to use would be supported.

thanks so much the bios string idea is the best thing i've heard all day. yes it will boot normally on durons and 133mhz athlons. i want to try and make it see a 166fsb sempron :) i'll do searches now, thanks for the input man.

You sure get your hands on a lot of crappy motherboards. You state that the board is an M848A in the body of your post, but for Manufacturer/Model you put "M848a-lu / MSI". You come here for help quite often, which is fine...but can't you at least post the correct info? I don't know what MSI has to do with anything but if the board is the M848ALU v2.1 rather than the M848A, I don't know why you couldn't find it?

As for the BIOS string, it's displayed on the POST screen.

Nice going jam, if he has m848alu.
I missed that.
Another SiS chipset.

CPU support and the bios version that supports them:

Be careful
- use the flash utility on the same page as the bios updates, or if a link is shown to one with the bios update, use that.
- read the flashing instructions
- cross your fingers, then maybe the chip won't fail while flashing

jam you know i'm past that. i felt the same way as you about the difference in the name of the mobo but: although on the mobo itself the LU part isn't written, it IS the LU. i went on the pcchips website and looked around for 30mins before i figured out why my board is the LU version. trust me, it's the one :)

where did i mention MSI ??? duude in the topic? i almost never touch that part when i start new threads.. i think i started to that's why the model is there.. sorry.

it's definitely M848a-lu because of the features i checkmarked. the lu part stands for the sis chipset .. and I'm not saying the m848a has a different chipset, but as I said, i checked all features. honest, i don't remember the difference that made me realize it's the 'lu', but if you want, and really want me to convince, i can go back and re-compare the two versions.

as for crappy boards.. that pc chips is gold compared to what i have powered on now on my monitor's second input :)

here.. AzzA 5MVD with the 598mvp chipset, socket 7, running XP on a 450 amd k6-2, overclocked to 500. i swear it's flawless, aside from shaky sound. not in winamp.. that sounds fine. however, when i try to run 'windows xp tour' and that female voice begins talking, it's all vibrating and shaking. i use that tour thing as a primary test on weak systems i build.. which means most :))))

any advice on what i can do to resolve the sound thing? has little or nothing with the overclock, it did the same thing at underclock from 450 to lower (5X83) and 5x95

i have an agp nvidia 16mb card, a cmi-4 sound card all properly installed, as well as the via 4.22 all in one chipset platform driver.

how can i put this so that noone here feels offended.. because that would be so out of sync with what i mean..

if all i would do is build high-end systems, would problems arise as often thus needing expert advice? common issues for newer systems get solved. i've had my pc for almost 2 yrs now, i never had a question about it and i doubt i ever will. only new thing about it, i discovered the jack sensing feature on its mobo and learned how to take full advantage o f my 5.1 channel speakers. aside from that, what could ever go wrong with an intel chipset and a dual core pentium ? it's not even about 'wrong', my wording is out of whack, but anything goes wrong with a device.. or a driver.. updates are standing by and hotfixes and stuff. like after installing my hp 4-in-one i had a problem opening hp director. i typed 3 words in google, and found out there was a patch released for hp director running on systems with IE 7. linked me to hp's site, installed a 50kb patch, and all was resolved. NO FUN ! :)))

jumpers are time-consuming, and so starting next week i'm gonna start bringing up PII and PIII systems from the basement :) i seen some processors on them stat stand up ! and one mobo has a a slot for the stand-ul procs, AND a regular socket for some 'pga320 or pga370' something :) we're gonna have crazy fun :D

I work on more old systems than I do newer high end systems, but why is it that most of the boards you come up with are crappy ones?

As for the sound problem with your K6-2 setup, what speed are you running the PCI bus at? If the board supports 100MHz FSB, why are you using 83MHz or 95MHz?

February 13, 2009 at 19:42:16
i'm not, it's on 100 now, but i tried going lower, thinking that can solve the sound issue. you're asking me what speed i'm running the pci bus at.. only jumpers on this board i found are:
multiplier jumpers, system fsb, vcore jumpers, and a set of 2 jumpers that looks retarded, it's about sdram clock / agp clock ratios. not ratios, but 'run as'. i tried them both ways, and the sound issue stands as a problem. should i lower the multiplier to 4.5 thus removing the overclock for good?

i should add, the sound wavering has to do (i'm pretty sure) with images being shown. that xp tour has moving images, and when they don't move, (between motion sessions) the sound is fine, the female voce is crisp. am I making myself understood? i hope so. i repeat, i blasted music out of winamp, no problems there at all.

"it's about sdram clock / agp clock ratios"

That's the one. AGP runs at PCI x2 or conversely, PCI runs at AGP/2. If the CPU is capable of 500MHz, just clock it at 5 x 100MHz, run the RAM at 100MHz & the AGP at 66MHz.

"the lu part stands for the sis chipset"

No, it doesn't.
Other models with LU do not have a SiS chipset.
PCCHips has varied which letters they use to indicate certain features over the years, and some letters stand for different things than they used to, and some are now omitted on newer models.
There used to be a page that explained which letters stand for what on their web sites, but it doesn't seem to be there anymore.
At the time this mboard was made USB 2.0 was a fairly new thing - the earlier 8xx series mboards and earlier models did not have it, so they used U to indicate the mboard has USB 2.0 support rather than just USB 1.1 or USB 1.0 support.
The L used to stand for LAN - onboard network adapter, but not all mboards that have that have an L.
LR stood for LAN Ready - the mboard had a proprietary connector for a proprietary LAN card.
PCChips doesn't use letters to stand for a make of chipset as far as I know, or if they do they are not consistant about it.
They used to use MR for "Modem Ready" - the mboard had either a proprietary connector or a standard modem riser slot, for a software controlled dial-up modem card.

"have an agp nvidia 16mb card"
"i should add, the sound wavering has to do (i'm pretty sure) with images being shown."

I use a similar system nearly every day, K6-III 450, Via MVP3 (Apollo) chipset (VT82C598 MVP, VT8C586B, the last and best MVP3 chipset), 2X AGP Radeom 7000 64mb video (1X/2X/4X card running at 2X). I only rarely have sound problems (ISA SB16 PNP).
I also rarely had any sound problems with my former card - ATI Rage Fury, 128 bit, 32mb, AGP 2X. Both cards (and nearly all ATI video chipsets 128 bit and later) have hardware accelerated DVD playback support.
Some video streams on the web are freeze frame rather than smooth, but DVD playback is excellent.

You have a relatively weak video card.
Look in your bios setup and make sure the card is actually running in AGP mode.
Initialize video first, or Primary Video, or similar, should be set to the AGP slot, NOT PCI.
Also, if there is a setting for it, make sure the AGP is in 2X mode (my Award bios does not have that).

If that doesn't help, a better video card will probably cure all or most of your sound problem.

I looked this up a long time ago, when my MVP3 mboard was new:
AGP 1X runs at 66mhz; AGP 2X runs at 133mhz; AGP 2X supports data burst speeds of up to 533mb/sec.

'auto-detect dimm/pci clk'

These mboards can use PC66 or PC100 ram (or older FPM and often EDO 3.3v DIMMS, but they run overall about 1/2 to 1/4 the speed SDram does).
Some of these mboards can also be overclocked a little above 100mhz, so you can use PC133 (or PC125 which was briely a standard) ram so that you can overclock, but only certain PC125 and PC133 modules will work (e.g. the chipset supports 256mb modules in each ram slot, but they must have 16 chips [8 on each side; double sided; DS]; all 128mb modules must have at least 8 chips - 4 chip ones of any PCxxx spec [there are some PC133 that have 4] will not work - the mboard may not boot at all).

The bios can read the specs in the tiny SPD chip that is on one end, and usually near the top, of all SDram modules to determine whether it's rated PC66 (66mhz), PC100 (100mhz), PC125 (125mhz), or PC133 (133mhz), and what CAS it's rated for at the frequencies it can run at.

With that setting enabled, if you use PC66 ram, the PCI clock is set to the ram speed= fsb speed / 2 = 33mhz; if you use PC100 ram, the PCI clock is set to the ram speed = the fsb speed / 3 = 33.3mhz; if you use PC125 or PC133 ram, if the mboard fsb speed is capable of being slightly overclocked, the PCI clock is set to the fsb speed / 3, e.g. 105mhz / 3 = 35mhz.

The max AGP speed on these mboards is directly proportional to the PCI bus speed. 1X AGP is twice as much as whatever the PCI bus speed is; 2X AGP is four times as much as whatever the PCI bus speed is.

If you disable that setting, these mboards have jumpers that set the fsb bus speed you can fiddle with, and those settings are used instead by the bios, but if you set that wrong according to what the ram is capable of, the mboard will not boot in certain circumstances.

Very few mboards were made that supported just 1X AGP - I've never encountered one myself - most early ones that support AGP at all support 1X AGP and 2X AGP.

How much you can overclock the PCI clock speed/fsb speed usually depends more on the PCI and AGP cards you have in slots that what the cpu will tolerate - some won't tolerate being overclocked much at all.

K6-2+ and K6-III+ cpus (I believe they are the same thing, different labelling - K6-2+ cpus are much more common) came out later, use a lower core voltage, and were made for mobile (laptop/notebook) use and can be overclocked more than the older K6-2 and K6-III ones made for desktop use. e.g. I have a K6-2+ 550 that has no problem running at 600mhz on my Epox mboard (6 X 100mhz; the K6-2, K6-III, K6-2+, and K6-III+ interpret the 2X multiplier as X6 on the cpu itself). K6-2+ and K6-III+ cpus have the built in L2 cache on the cpu, the same as the K6-III's do. The K-2s do not.
However, you must be able to select the core voltage the K6-2+ and K6-III+ requires - 2.0v, or no more than .1v above that - they will burn out if you can select only 2.2v for the lowest core voltage - sometimes there are un-documented settings you can set jumpers to, to get a voltage below that.
Also, there were few desktop mboards that had bios versions that could recognize K6-2+ and K6-III+ cpus, and some older ones can't recognize K6-IIIs either - if the bios does not recgnize them, they run the same as a K6-2, and the L2 cache on the cpu is not used.
If the bios DOES recognize them, the L2 cache on the cpu is used, and the mboard L2 is used as L3 cache, making them more efficient than a K6-2 of the same speed, if the mboard has L2 cache.
e.g. My Epox MVP3-G5 does recognize them all when flashed with the last available manufacturer's bios version - Sisoft Sandra rates the K6-2+ 550 running at 6X 100 at equivalent to a K6-2 running at 720mhz! It also rates my K6-III 450 running at 4.5X 100 as equivalent to a K6-2 running at 520mhz.

"i even tried running the vcore to 2.8"

The K6-2 and K6-III desktop cpus will BURN OUT in a short time if the core voltage is set to more than .2v more than the rating on the cpu, probably regardless of whether you use extra cooling!!
Upping the core voltage does NOT affect the performance of these cpus noticably, but it does make them run noticably hotter. The only thing upping the voltage might affect is you might them be able to overclock them a little more.
The cpu cfm rating isn't critical, but the cpu heatsink should have at least 3/4" high fins, or higher.
The one K6-2 550 cpu I have is rated at 2.3v. Other K6-2 and K6-III cpus may be rated at 2.2 or 2.4v, or less often, 2.3v

I found info on the web that says the K6-2+ and K6-III+ cpus will BURN OUT in a short time if the core voltage is set to more than .1v more than the rating on the cpu, probably regardless of whether you use extra cooling!! They run cooler, and run cooler even when overclocked - if the cpu heatsink has at least 3/4 high fins, they're fine with that.
The K6-2+ 550 cpu I have is rated at 2.0v.

You get the best perfomance overall with the highest fsb speed the ram can tolerate. Most 100mhz ram will not tolerate a fsb speed much over 100mhz if any at all.
If you jumper the sdram speed to 100mhz, if the mboard is capable of having the fsb set to higher than 100mhz, the mboard probably will not boot at all if the fsb is set higher than 100mhz.
If you jumper the SDram speed to 100mhz, the PCI clock jumper must be set to fsb or ram speed /3 = 33.3mhz at 100mhz - the mboard will definately not boot if that is set to fsb or ram speed /2 .

On my Epox mboard I cannot set the AGP speed via a jumper or in the bios - it's directly proportional to whatever the PCI bus speed is. 1X AGP is twice as much as whatever the PCI bus speed is; 2X AGP is four times as much as whatever the PCI bus speed is. If the AGP video chipset is capable of AGP 2X, the bios automatically runs it at AGP 2X.

The only fsb speed over 100mhz I can jumper for on this Epox MVP3-G5 is 112mhz - NONE of the cpus I have tried will run at that setting - the mboard does not boot at all.
Apparently, on some other SS7 mboards you can select lower mhz settings over 100mhz, and some K6-whatever cpus will run set to that, if you use all PC125 or PC133mhz ram and settings are suitable otherwise.

"sdram clock jp7 jp 8

My guess is that "op sh" means OP = OPen (no jumper), SH = SHut (jumper in place)? Not sure about that. But "run CPU clock" means the RAM will run at the FSB speed (100MHz), "run AGP clock" means the RAM will run at 66MHz.

"so for my sound card(s) to run at normal frequency, how should I set those jumpers, and what ram should I use? I have pc-100 and pc-133"

Like I said in a previous response, with the CPU at 100MHz FSB, the RAM should run at 100MHz & the AGP at 66MHz. The PCI speed is runs at 1/2 AGP speed.

As I see it, you have 2 major problems that are hindering the ability to watch have a crappy video card & you're using the onboard sound. The video card should be self-explanatory...the onboard sound uses the CPU. That's not so much a problem with modern systems but when you have a CPU running at 500MHz, it really can't afford to be handing out MHz for other hardware to use. Disable the onboard sound, install a PCI sound card & try running videos in a window, not full screen.

"i did all the updates from microsoft, besides sp3. i left that out i though i would not need it"

Why do feel you don't need SP3? Tests have shown that it actually improves performance.

The PCI bus speed your sound card uses probably has absolutely nothing to do with your sound problem.

I haven't had problems with sound like you describe on any system of about 300mhz or faster whether it has integrated sound or not, unless the display adapter was inadequate. For that matter, SB16 cards like I am using with the Epox system are notorious for using more of the cpu time than other sound chipsets.

Your bios sets the ram settings to the least of all the specs of all the installed ram modules by default.
- if you install both PC100 and PC133 ram, the mhz the ram runs at will be a max 100mhz, and the CAS setting the bios uses for it will be the slowest rating at 100mhz of all the installed modules, if the the CAS ratings at that mhz are different.
- if you force the mboard to use a fsb speed above 100mhz by means of a jumper, the mboard will probably not boot at all
- if you disable default settings in the bios and set certian things to settings the ram can't actually support, either the mboard will not boot the next time you attempt to boot, or the bios will automatically reset the settings to what will allow the mboard to boot despite your mistakes.

"the board has jumpers for up to 100fsb. and 5x multiplier. hence the max overclock i can do on this 450mhz cpu is up to 500mhz."

Your maximum is actually 600mhz.
Read the last part of response 14 again. The K6-2, K6-III, K6-2+, and K6-III+ cpus interpret a multiplier setting of X2 as X6 on the cpu itself.
That said, I found by trying it that the K6-2 400, K6-III 450, and K6-2 550 cpus will either not boot when you set them to the next highest, or the one above that, multiplier setting, with the fsb speed set to 100 or 95, or they do boot but all sorts of various weird events happen.
The only one I had no problem with setting the multiplier higher with was the K6-2+ 550 - it runs fine at 600mhz - the X2 multipler being interpreted as X6 by the cpu itself, at 100 mhz fsb speed.

A K6-2 400 will work fine with the X2 multipler being interpreted as X6 by the cpu itself, at the 66mhz mhz fsb speed, but the overall performance of the system is much better if it's set to X4 at 100mhz.

I have a PowerColor ATI chipset 9250, the REX model (has video in) - I haven't tried it with my Epox mboard, but it works fine on other mboards with faster cpus (at 2X, 4X, or 8X) and I don't get sound symptoms like you're getting on those other mboards either.

You may have something else going on.

DO NOT use the last PCI slot of the PCI slots on the end closest to the middle of the mboard for a card, unless it's a PCI video card! That slot is forced to use the same IRQ as the dedicated video slot, or the onboard video if the mboard has that, and that is a frequent cause of problems, unless the card is a PCI video card (in which case the onboard video is disabled, or the system is using either the AGP card or the PCI video card, not both, at any one time).

Look in System Information in Windows on the left at the IRQs devices are using. If any card or device uses the same IRQ as the sound card, you are likely to experience problems, unless the IRQ is for something other than the video that's built into the mboard, OTHER THAN the USB, or unless many devices are using IRQ 9 and the sound card is one of them.

If ANYTHING is using the same IRQ as USB controller related devices, you have an IRQ sharing problem you must fix.
See the latter part of response 3 in this:

If the soundcard is sharing an IRQ with another device, other than IRQ sharing or similar, try the card in a different PCI slot.

If that doesn't help...

Do you have another sound card you can try? If your mboard has ISA slots, it doesn't matter much whether the card is ISA or PCI.

Do you have other cards you could try removing??
I once tried a Lava PCI parallel port card on the Epox mboard - that disables my SB16 sound completely - apparently Lava knows about the problem yet had never fixed what causes it.

I was trying to connect a Quick Cam as well as my parallel connected printer. I found that the only EPP/ECP capable card with a parallel port that worked properly with that original Quick Cam (greyscale; connects to a parallel port) was an ISA Multi I/O card, with the other stuff I didn't need disabled by jumpers.
My brother tried a parallel port switch box to do the same thing with the same Quick Cam model, but you had to reboot the computer when you needed to use the port for the other device.

i think the sound card is exactly in THAT pci slot you mentioned. i'll try a different one, yes i have ISA soundcards around here as well. again, this board has nothing integrated, so onboard video need not be mentioned. i will try a sb ISA card, and remove the NIC while testing sounds. what really boggles my mind is, i've set up a luckytech p5mvp3 a while back, with a 32mb rage fury agp card and an ISA sound card, and that system ran flawlessly under xp, movies and sound were never an issue. however, i was using a mobile 500mhz amd k6-2+, which is a superior cpu. i'll post back on this after i mess with my own pc now, gonna try your advice on my ati ccc.

I always say it's best to doublecheck.

okay here it goes..

i took out the agp card completely and put in a pci vga card with 2mb of ram. guess what, no more shaky sound. i repeat, i had tried over 10 different agp cards. so now what the hell can this mean? i really would hate to leave this pc with a pci vga card !

is this about that ratio thing with the sdram clock jumpers? see, the last system i built using chump parts like this, was a luckytech p5mvp3 mobo with a 500mhz cpu. but although that board looked so similar to this AzzA, it had instead of this sdram clock jumper, a jumper that locked the agp clock to 66. this azza board, on the chart about the fsb jumpers, also has a column with agp values. so for each fsb, the agp clock is affected aswell. example: fsb100 makes agp run at 66. fsb 95 = 63 agp. 83fsb = 66agp. I don't know where to start :)

I always say it's best to doublecheck.

You problem has got nothing to do with the speed the AGP or PCI bus is running at!

Look in the bios when the video card is installed. The setting Initialze video first, or Primary Video, or similar should be set to the AGP slot or similar when an AGP card is installed, or to PCI slot or similar when a PCI video card is installed - often, on these older mboards, the bios does NOT do that automatically.
The AGP card cannot actually run in AGP mode in Windows unless that setting is right for it - if that's wrong, in 2000 or XP, it still works but it's in PCI mode - in Win 98 and 98SE, and probably ME, you often get no video at all (blackness) once Windows starts to load if that's wrong!

If that doesn't help, I think we've covered everything else - I'm assuming you have made sure the sound card is NOT sharing an IRQ with anything else other than what I said is okay - did you try a different sound card?

The only thing I can think of is someone damaged the AGP slot circuits at some time in the past. You may have noticed the contacts on the AGP card (and in the AGP slot) are in two rows vertically and staggered a half space - all it takes is as little as for someone to have plugged in or unplugged an AGP card ONCE when there when the power supply still had live AC to it and it was connected to the mboard to cause damage to the video card or the AGP slot circuits or both.

Similar can easily happen with a PCI-E video card - you may have noted the contacts are very close together - the slightest mis-alignment of the card when plugging it in or un-plugging it when the power supply is still getting AC can damage the card or the slot circuits or both.

actually, without making any changes at all, i took out the pci card and put in an nvidia tnt2/pro, a 32mb card. and it just works fine, no adjustments made. i'm stopping at that, and am glad it finally got settled.

I always say it's best to doublecheck.

Ok, so you have achieved a solution - that's good news.

Make sure the AGP card is set to AGP in those settings in the bios Setup for the best video performance.

Come to think of it I think I have set up mboards with CMI sound built into them (Hsing Tech /PCChips mboards often have renamed sound chips that are actually CMI chips), but I have not tried any CMI chipset cards. I you didn't try other sound cards maybe it's a CMI chipset sound card only problem.

Did you check the IRQ settings?

yes all irq's were fine no conflicts. i'm actually facing a much worse issue on my own system, maybe u can have al ook under my windows xp topic?

I always say it's best to doublecheck.
