flush bios

Point value changed by question poster.

Hi,

There are a couple of things you can try.

The biggest problem you'll have is getting your PC to read from the floppy drive again. Thats bad - and uncommon too.

Often when the BIOS is bad, the machine will still attempt to boot from the floppy drive. This is the failsafe to get back from a stuffed BIOS upgrade.

Firstly, clear out the CMOS. You can do this by either locating the jumper on the motherboard and moving to the clear position, waiting 30 seconds and moving it back (you manual will show you where it is...) or by removing the battery and waiting a while.

Once you get the PC to try to read from the floppy when you turn it on, you're on the road to recovery...

There are several options after that (including burning a new EPROM) and they're very well described at the following site...

Click on support. Then bios. Then halfway down the article is a link "How to recover a corrupt BIOS"

Take a look at that. It'll show you what todo next. Take a look at this article even if you dont manage to get the floppy to work as it has solutions without it.

Good Luck,
Tim.

It is true that if you used the wrong upgrade ( Flash ) that your system would need a new bios chip, this could be received by the Bios manufactor. You can reprogram a bios chip using eprom. I had one once on an old acer system, And I took the ClearCmos jumper off the system board and this worked. Hope this helps.

Giving the Bios in system would have been a help
For Award BIOS
Make a bootable floppy disk
Copy the Award flash and correct Bios file to floppy
Create an AUTOEXEC.BAT with bios file name *.bin the content
Boot system with floppy
Reflash the biso and reboot
If this does not work you can check www.badflash.com for bios chip at approx.$20

When a BIOS becomes corrupt, there's not a whole lot that can be done. You most likely have only a couple of options:

Option one: (if it's a particular award BIOS):

Boot block: Some Award chips may have a boot-block on them, a segment of information not rewritten during a flash. Supposedly it will be able to execute an AUTOEXEC.BAT file on a floppy disc (and nothing else) so it may be possible to resurrect the BIOS by putting system files, the flash program, a source file and an appropriately-written AUTOEXEC.BAT file on a floppy before reboot.

Option 2:

Hot-swap: It is possible to resurrect the bad BIOS by using another, working motherboard. It is best to take the bad chip to the site with the good board because it exposes the known good BIOS chip to the least number of insertions and extractions (and subsequent risk of pin damage).

Hot-swap process:

Step 1: Prepare a resurrection disk.

Prepare a clean floppy with:

System files. To perform any BIOS programming, the machine must be booted in DOS mode only without any drivers loaded. Use the Windows format utility (in the right-click menu) and select the option "Copy system files."
An updated version of AWDFLASH.EXE or the appropriate BIOS flash program.
A correct version of the BIOS source file.

Step 2: Reboot to DOS mode.
Shut down the computer and lay it on its side.
Remove all cards and other hardware over the motherboard except the video card. If it is a PCI video card, move it to the slot closest to the AGP slot. Insert the resurrection disk.
Power up and allow to load all the way to the A:> prompt.

Step 3: Pull the good BIOS chip.
Ground yourself if necessary.
Use a PROM or IC puller to carefully remove the chip without bending any pins. Brace your arms against the case and pull upward as directly as possible. Make an effort to ensure that both ends of the chip are pulled equally hard. The ch
