Specs: Windows XP, Intel P4 1.9
Happy New Year Everyone. My daughter's PC is giving me a bios error message, during POST. "unknown flash type" although i never flashed its bios. so i've decided i'm gonna flash it now. my first bios flash. I'm gonna paste the details from the document i made up using info from dr hardware

CPU - SL5WH

smbios= no info

PCI BUS

host bridge, pci-pci bridge, isa bridge, ide mass storage controller, usb serial bus, audio multimedia, these are all by VIA

VGA Video controler: nvidia fx5500 256mb ram


on the mainboard itself, it says P4VXAS, but low and behold, on the ecs AND the viaarena website, that mainboard is not mine. i did not find it, everytime i thought i finally located it, i'd download the manual, and didn't match, it would say it has 3 rows of simm and 2 of dimm, or that it supports AGP 8x. My Mainboard supports AGP 4x, or at least that's the highest option in my outdated bios. and I have 3 RAM slots, SDRAM the ones with two notches.

the jumper settings matched from the other manuals, and then when i finally installed dr hardware and it told me the northbridge chipset is the VIA Apollo P4X266, i finally found the manual, but then again, the manual says nothing about the writing on my board, P4VXAS.

This is why I'm here asking for a hand, I need to do the following:

1. back up my bios
2. update bios because it's outdated and it throws out a message "unknown flash type" during POST

I got a floppy installed, so i'm here and ready, but won't do it until one of you guys tell me how to back it up. i don't even have the bios flash utility, all i know is that need a floppy drive and some floppies.

I always say it's best to doublecheck.

If the computer has been running fine for years and just now started giving your that message I would not consider flashing the BIOS. First of all you are not sure of the exact motherboard model, let alone the version. Flashing with the wrong file will result in a dead motherboard.

I suggest you boot into the BIOS screens to see if the date and time are wrong. If so, change the silver coin shaped battery. That battery hold CMOS settings when there is NO power to the motherboard.

For the time being resetting the values in the BIOS screens MAY stop the message.

It is possible somthing happened to corrupt the BIOS, in which case it may be necessary to flash it. You don't want to do that at this time though.

If the date and time are correct then you can try clearing the CMOS and then resetting the values. There are two methods to clearing the CMOS. The preferred method is to use the jumper marked clrcmos. There are three pins in a row. The jumper is currently set in the run position. All you need to do is to remove that jumper and temporarily place in the other possible position momentarily. Then restore the jumper to the original run position. You must have the computer unplugged when doing this.

The second method is to remove the battery mentioned above for a period of time and then replace. Both require you to enter the BIos screens at the very next boot cycle to reset values as needed. You may need to set CPU values and memory settings. I suggest you preview these settings and write down values prior to clearing. There are many screens. The instructions on how to move around and make selections are on the screens.

Exercise proper static precautions when working inside the case. A static charge from you to the components can permanently damage them. If the power supply has an On/Off switch on it then DON'T unplug the computer. Instead switch it off at the PSU (power supply. That keeps the ground connection in place. Touch the metal case immediately before touching anything else in the case.

Hope this helps.

How about just trying a Bios reset before attempting a Flash. It might be only a CMOS corruption. It's extremely rare for a bios to become corrupted.

i could have sworn it was, then i downloaded the manual and found the p4vxad has agp8x and onboard lan. mine has agp4x (in the bios as the max option) and no lan onboard. it it would help, i can take a good photo of it right now it's opened, next to me on the desk.

i did about 5 cmos clear jumper moves.. guys i read the manual over and over and i'll tell you when this error began showing up. . i fiddled with overclocking on it. and it was fine, it was doing 2.3ghz with an added case fan. then i went and used atitool to oc the videocard which at the time was a weak ati radeon 9200se. that's when it happened, the system rebooted, and checksum error flashed on the screen, but with some different kind of series of beeps, not the ususal after clrcmos beep. i then cleared the cmos once more, and there it was, this post error message 'unknown flash type'. but the system WORKS, i boot into xp and i'm fine. however i'm afraid to oc the proc now. not until i know it's safe to . so along with you guys, i can ignore that error during post, and use your advice on oc-ing it if it's the better choice. i do NOT want to flash the bios. not unless it's absolutely necessary. but then again, i do want to stay on 2.2 or 2.3ghz with it, it now has an fx5500 radeon, much better v-data ram 133, and i know it can work better. the system is sluggish. it drags. at 2.3 it was great. but when my daughter went on to play online doll-dressup games it started acting up. i should have just bought the new video card then. instead, i tried oc-ing the 9200se. and something messed with my bios (i think). what else could it be ?

in reply to jam, that's exactly the mobo manual i keep finding. it's not it. my mobo supports 4x agp, not 8x, and it has no onboard lan.

You probably have an older or slightly different version of the model.

i finally found something coherent.. here it is http://www.via.com.tw/en/downloads/...

that explains the differences between the southbridge vt8233, vt8233c and vt8233a. i have the vt8233, the one without the integrated lan. i think it's the weakest, but nevermind all that. i'd love to find its manual for one thing. the mobo user guide not comparison white papers etc. and then back to my bios problem if i can.

wow a big THANKYOU is in order i finally have a proper place to start with this. as a matter of fact, i reset the cmos 30mins ago, and now i was in bios doing the setup. it's a 1.9ghz p4 in there, and with this mobo i want it at 2.2 or a little above. and i'm pretty weak with the bios settings so i got a bios optimization guide i found online, problem is, dude that wrote it talks about 32mb video cards like they're the new thing out. so it's an old guide. and like i need to know, what's better, getting the cpu clock up, or getting the multiplier up. the proc supports up to 19x it says on its specs. but i went up to 12x, with the clock at 107/71/36, and the cpu shows up as 2.03ghz but if i put the multiplier at 8x and try to raise the cpu clock to 110/then these values here are different and i'm lost./

"Socket 423 was a CPU socket used for the first Pentium 4 processors, based on the Willamette core. The socket was short-lived, as it became apparent that its electrical design proved inadequate for raising clock speed beyond 2.0 GHz. Intel produced chips using this socket for less than a year, from November 2000 to August 2001. It was replaced by Socket 478."

and you know what, that's proving to be entirely true. no matter what i do with the multiplier, it's obviously locked and that's that, because the cpu frequency does not change. the only time it changes is when i change the bus clock. and i can't get that over 110/73/37 even if i disable everything in my bios and add 0.1v to the core. even then, it's not steady. so i'm going to leave it at 107/71/36 and then hopefully i can run my ram at 133 instead of 100 and maybe use riva tuner for better graphics processing. would that be wise ? i'm already way off-topic here i've gone from bios issues to oc issues i'm sorry. i'm gonna try and attach screenshots (photos taken with my phone) maybe you guys can breathe some inspiration on me here.

it worked out for the best, 107/71/36 clock with the multiplier on 8x (not that it makes any difference) and upped the DRAM to 133 and lowered the vcore from +0.1 to +0.05 and it's stable thru benchmarks and stress. thank you all for input it's greatly appreciated.

i can't find the manual for the mobo still to this day. maybe someone here can help me. it's the P4VXAS - ECS Elitegroup with agp4x not 8x. please.

that's the closest anyone ever got :D but mine only has three ram slots. however, this last one you found is good enough thank you so much.

if you have the time, maybe you can look at my new topic about the axda2600 ?
