Did you create the floppy with this

@echo off
if exist oldbios.bin goto old
awdflash.exe newbios.bin oldbios.bin /py /sy /cc /cp /cd /sb /r
goto end
:old
awdflash.exe oldbios.bin /py /sn /cc /cp /cd /sb /r
:end

and add the autoexec.bat to it

ok, sorry im sure im being dense here, i have so far created a boot disk, added flash program and my .bin
after your last post i opened note pad and put in

@echo off
if exist oldbios.bin goto old
awdflash.exe newbios.bin oldbios.bin /py /sy /cc /cp /cd /sb /r
goto end
:old
awdflash.exe oldbios.bin /py /sn /cc /cp /cd /sb /r
:end

saved that as autoexec.bat to the floppy

not sure how to create a floppy w/ the above code, and then add an auto exec to it

just so we're clear here...you know this is a last ditch effort and it is quite likely that your cmos chip is bad.

http://www.thecomput...otforsteely.iso

You need to burn this image to a CD and boot your computer with it--this is different than burning a file to a CD. If you do not know how to burn an ISO image, then download the following program to a Windows XP machine, install it.

make certain you download the proper installation for your version of windows (service pack 1 or sp2)

http://isorecorder.a...isorecorder.htm

After installation, right click the bootforsteely.iso file you downloaded above and choose COPY IMAGE TO CD.

Then reboot your broken PC with the CD in the CD-ROM drive--make sure that the PC is set to boot to cd rom first in the bios boot order

This is a DOS boot cd with your flash bios update on it

It is not automated

PLEASE -- ANYONE ELSE LOOKING TO UPDATE THEIR BIOS DO NOT USE THIS__IT WAS CREATED SPECIFICALLY FOR THIS MACHINE AND ANY USE OF IT WILL KILL YOUR PC

Set the PC to boot to CD first

After the machine boots, it will look just like a windows 98 bootdisk starting from a floppy

Choose START COMPUTER WITH CD ROM SUPPORT

The boot setup will complain that it cannot find a fat32 drive if your pc is set up with ntfs--that's ok--we do not need to access the drive

at the a:\ prompt, type

look up a couple lines and you will see the drive letter assigned to the cd-rom

Drive X = DRIVER MSCD001 unit 1

whatever x is, type

X:
<enter>

now type
FLASH802a.exe VDC49.Bin
<enter>

Follow prompts to flash bios

gerryf thanks for the reply, indeed i was afraid the cmos chip is bad
as for making a boot iso, no burner on the pc im using, and the bad pc will allow nothing but inserting a floppy, cant get to the bios to change boot sequence
the closest ive come to some kind of resolution was finding the award flashing program that was actually named awdflash.exe, and putting it on a boot floppy w/ my .bin file the flash program starts and the .bin file is put into the blank where it says program w/ but since the keyboard allows not input i cant press enter
im still mucking around w/ different autoexec.bat's and think if i can find the right commands for the autoexec file it might be possible to fix, funny all thats stoping the flash of bios from happening is a simple press of an enter key....ah well such is life
i really am appreciative of all the help thus far

ok



download the attached file, extract

insert a floppy disk and run

drdflash.exe



follow prompts to create a bootdisk

when complete, copy flash80a.exe and vdc49.bin to the floppy



insert in bad machine

boot bad machine



at a:\ prompt, type

flash802a.exe vdc49.bin

<enter>



do not use any other flash programs. Use the one intended for this machine, which is the one in the archive that is attached.

Well then, I apologize. It seems you have an automatic bios recovery issue here, not a poorly made disk

OK, let's try this.

Get a blank, formatted floppy and place ONLY the BIN file on it.

Unplug your case, open it up and disconnect the cable from all drives except the floppy drive

Reboot...when your screen comes up, quickly press ALT+F2

see if it can find the BIN file on the floppy

When you pulled the battery out did you unplug the computer from the wall socket (or the connection to the power supply unit)? If you didn't then it is as if you did nothing. Disconnect and pull the battery out for about 20 minutes.

When the battery is out use a voltmeter to check the it's potential. It should read not less then 3 volts.

Try replacing the battery with a new one. The battery is probably dead.
