Re: Flashed the bios with wrong version PC is unusable

When you flashed the bios, it should have asked you if you wanted to back-up the original bios file. Hopefully you did. If the system wont boot from a floppy so you can reverse the flash, then your only options are a new mobo or contact the board manufacturer for a new bios. The bios plugs in and is replaceable. Sometimes though it cost as much for the bios as it would for a new mobo.

Re: Flashed the bios with wrong version PC is unusable

Hi, I dont like your chances a lot. Next to the cmos battery you will find a set of jumper pins [3 pins] move the jumper from where it is set onto the next pin and leave it there for at least 10 seconds then replace it back in its orriginal position. This will reset all the orriginal bios settings. If the update flash you have done doe's not allow this to reset, get onto the ASUS web site and ask for tech help, the response may be slow but this is your only option other than another mobo.

Bios was flashed will not post to bios. Will new cmos battery reset bios?

hi no this board is now u/s any problems flashing a bios will make the board unusable, due to the fact is, it requires the bios for start up if that is corrupt you have no choice but to get another board, changing the battery will only put the bios back to default if it was ok, it will not do it if it is corrupt, sorry but thats the way it is

This motherboard has been working flawlessly for months. Suddenly all entries in device manager starting with "system management bus" have the yellow Bang! symbol. The all say they need the driver...

This motherboard may need to have the firmware in the bios re-flashed with the latest version.
All functions in the motherboard need the bios. If the bios is corrupted, you will have problems similar to what you have stated.
Look up the bios on the Internet for the version of motherboard and the bios.
Re-flashing with the wrong version will ruin the motherboard's bios. Be sure you have the correct version and re-flash the bios.
Then try the board.

Asus P3B-F Motherboard

Download a manual from the ASUSTEK website, I have read many forums related to issue's with ram and from what I have learned with the ASUS boards is that dependind on the bios and the model, each slot, for some unknown reason can only recoqnize a maximum of 128MB per DIMM slot? My board has 4. For example, no matter what I install for Ram the motherboard will only read 512, some of the forums on ASUSTEK reccomend reflashing the bios with an updated one, but now, with the age of these computers i find it difficult to find a Bios upgrade. It is ridiculas, the Bios should come from the manufacturer ready to handle the maximum Ram of 1GB, which is my case with the ASUS P3B-F Pentium 3 with a 850MHZ processor.?????????

Can't boot after upgrade bios f6

If you flashed the BIOS and it stopped for whatever reason or you flashed the wrong BIOS version, there is nothing that you can do except to replace the BIOS IC.
  • If the system has a boot block to restore the original BIOS, use it. Refer to your motherboard documentation.

  • If not, you will need to contact the system or motherboard manufacturer for a replacement.

Hi Moin,
Is there a reason you need to know what those numbers are for?
Asus still has the driver software, manual & bios files for the P2B-F MB you listed above.

For the Asus P2B-F MB click here:
Here's a picture of the P2B-F MB.
Neither of those numbers you listed above are chipset numbers.
If this is not what you need. Than rephrase your question.

No video etc.

on the motherboard will be a JBAT1 terminal with the jumper across pins 1-2, so put jumper on pins 2-3, then back to pins 1-2. If not JBAT1, then it may be a 2 pin terminal called CLRCMOS, of which you put a jumper across the two pins for seconds then remove. Although, i can't think of a way to update the bios without seeing whats on the screen.
