The computer in question is a 333 INTEL CELERON
with AMI bios , BXPRO chipset which is a relabeled SiS (600/5595) 100Mhz Chipset.
PC Chips Model: M747 V5.0 61-1210-000747-00101111-071595-M747-M747V5.0-H

I have these two URLs which seem to have a suitable bios upgrade :

but I'm not sure. The two versions have a different time stamp so I guess the latest one should be used.
What's most important for me to know is will an
upgrade of the bios will enable the computer to recognize a 10 GB disk, the purpose of this whole upgrade.

Shouldn't be a problem. The updates deal mostly with new microcode to support different cpu's such as P3 550mhz. If I remember correctly one of the bios updates for the M747 PCCHIPS Board dealt specifically with 32 gig HDD and larger support and this has been carried over into the most recent bios updates.

But as always you should check the HDD before you flash, you may already have the support.

Thanks for your insight.

Maybe you can help me further on this : I downloadsed the AMI flash program from :

extracted the contents to a floppy disk and added both ROM files. However, when I run the program F82741.exe in real DOS mode, I get a message saying : "error 3 - file does not exist". Any idea what file is missing, if any?
Also, in the help file there it's written :
and ther's no AMIFLASH.COM in the zip file.

Meanwhile I found this :

"Error messages such as 'File not found' or 'ERROR 2: File does not exist' indicates that you are either trying to flash your BIOS from a floppy diskette that may have bad sectors, or you are not typing the name of the BIOS file correctly (including the extension). If you receive this message make sure that you are attempting to update your BIOS from your hard drive and that you are typing the correct name of the BIOS file including the extension. "

I did try to run just the flash program w/o adding the bios file itself in the command line because I wanted to get the opening program screen where one can save the current bios. I'm afraid that if I wrote : AmiFlash.exe BIOS.rom than the procedure will start right away. Isn't that the case?

The program does indeed have to be run from pure DOS, AKA bootable floppy, SOP on this is amiF2m(or the name of the version you are using).exe (name of file.rom or the like) and you will have the option at the first menu screen to save your existing bios. The main reason for this is the parts have to match with the code for the program to run.

Better safe than sorry as it were, you should probably use the Flash utility provided by the mainboard manufacturer and not the AMI flash utility provided by AMI. Some board manufacturers alter their code in such a way as to allow for only their flash parts to be recognized. AMI makes their flash.exe to be used on any flash part, even Phoenix/Award flash ROMS and is stated as such in their disclaimer.
