Hi all,

First I went through few interesting posts in this forum by doing search as well as other interesting websites. I learned alot, but unfortunatily after the disaster happened

What happened?
I downloaded a newer flash version into a bootable floppy with (Autoexec.bat) command and (awdflash.exe) update exe file. However i did the upgrade wrongly be executing (awdflash.exe) directly which is WRONG. I should execute (autoexec.bat) file which has the right command plus the necessary switches like the following:

Code:
awdflash mbx0202.bin /py /cc /cd /sn /cp
During the update, it reached up to 30000 bytes and then it stopped with a flashing error message that said (BIOS upgrade fail !!) .. so I tried all keystrocks possible but with no results. YES, I rebooted the machine and duhhh ... the screen is blank and dead!!

sooo .. I rushed to the internet looking how to recover this horrible mistake. My pc & motherboard specs is as following:

Micron Client Pro CS, PII 500Mhz, 128MB
Motherboard: DR737, Award BIOS V4.51PG, Micron BIOS 2.71, BIOS Version (7/23/1999-i440BX-W977TF-2A69KB3FC-00). Motherboard silkscreened part number (MBD001111-01)
Reason to update BIOS: to support my new 80GB western digital hard drive.

Actually, before upgrading BIOS, I tried to install the overlay tiny program which should solve the problem. However it did not, and everytime it boots to hard drive the utility start loading and asks me to press (C) to start setup from CD-ROM, but it does not even Windows 200 CD is loaded and I pressed C several times. So I decided to solve it deeply and update my BIOS.

Back to BIOS problem. Now I learned that there are several ways to recover a failed BIOS flash, including the following:

1- Hot plug of BIOS by buying a new chip
2- changing CMOS recovery jumber. Actually I have this jumber in my motherboard but I don't have the manual for mobo since MICRON did not provided one.
3- booting with a newer floppy with a backup of old BIOS. For my good luck I made a backup of my old BIOS into a floppy before flashing, and now I have a new floppy with the correct (autoexec.bat); my old BIOS, and (awdflash.exe) exe file. I learned that I can force the PC to load from floppy by pressing control+home keys? ... ?!?!
4- by changing the motherboard. which is not worth it since the PC now won't worth more than 100 US$ as a used old PC.

I'm very interesting to do the 3rd solution, which is restoring my old BIOS. I have the floppy and all necessary files, but I just need to force the PC to start and load the floppy. I found a site which explains how the mobo loads and start reading from FDD and how it make beeps for loading the BIOS and long beep for a successful update. I wish I can do it, but my PC won't give any indication it can start to load anything!! it seems the CPU can't load or do anything.

I found this quote in a previous post in this forum
As mentioned, the standard boot block contains startup code which is often, but not always, left unflashed during an update. This startup code is IBM PC code, so expects to be on a system with ISA MDA video and will let you boot from the floppy drive. So if this is intact, and the m/board has an ISA slot, you may be able to fit an ISA video card and attempt to re-flash. If the system attempts to boot, but there is no ISA onboard, or the video doesn't display, you may be able to re-flash blind. That is, once DOS loads, type the flashing commands, run the flashing program from the autoexec.bat file or if your BIOS flashes with a key combination, you have to just know when it needs to be pressed without seeing the on-screen prompt.

Just to be contrary, if you manage to re-flash and the results are the same, or if the system will not boot at all, it may be because the boot block did need to be flashed too, but wasn't. This can be due to recent versions of awdflsh.exe, which default to not flashing the boot block, it can be worth using the AMI flash utility to avoid this problem. If this is the cause of the bad flash, and the system simply will not boot, other recovery techniques will be needed, like the EPROM programmer already mentioned, or a hot swap.

By the way, if the system won't start up at all, don't overlook the CMOS reset jumper - after the flash, the CMOS memory may be corrupted and setting a parameter that won't let the CPU run properly.
Please help me and tell me how can I force my mobo to load the floppy ?
