I have an old Dell Optiplex GXL 5133 computer.

I would like to do an AMD K6 400 powerleap upgrade on it but the DELL Award BIOS has a check that prevents the computer from booting with a non-Intel CPU.

I remember seeing someone on the boards here that had experience modifiying their PC BIOS (I think it might have been Petr).

Anyway, this seems like it should be a simple modification. I don't know if the check is done using CPUID or using the CPU string.

Here's a link to the BIOS file...

Inside the zip file is the EXE bios installer.

When I looked into this several years ago, I believe the BIOS installer was compressed with an exe compressor. I don't remember which one but I'm pretty sure I managed to un-compress it. However, I must have deleted the fruits of my labor because I can't seem to find it anymore.

Any help with this endeavor will be greatly appreciated.

Thanks.

I managed to get the unpacked. Here's the unpacked BIOS installer...

For the curious, I used UN-PACK 2.2 to figure out what it was packed

with (LZEXE) and I used X-TRACT v1.51 to unpack it.

Hi Krick,

I'm sorry, I have no experience with this. Long time ago we had Intel Zappa boards with this limitation and we've solved it by buying Mr.BIOS replacement BIOS - see http://www.mrbios.com/ .

From the little I know, DELL motherboards usually are just "normal" OEM motherboards, maybe you can find the original BIOS on the actual manufacturer site.

Or you might want to have a look here:

Cannot say if it will help, though..
