I have a Slocket 8. I'm trying to get it working in a 440EX board with an OEM branded Award 4.51PG BIOS. The board is known good, working fully with a Deschutes P2. When I put the PPro + slocket in there, it boots up but the system hangs right before it prints the CPU ID string. I'm assuming the problem is indeed lack of BIOS support, since if the chipset itself was incompatible it wouldn't even boot or display anything. I've also verified the VRM on the board supports 3.3v.

Anyone up for helping me hack the BIOS to add microcode support? I can dump it with AWDFLASH and post it here if anyone is interested.

Hi, I came across this forum, it could help finding what you are looking for https://www.bios-mods.com/forum/

One thread caught my eye: https://www.bios-mods.com/forum/archive/index … ad-32206-1.html

Also interested to learn more about BIOS modicfication required for PPro cpus, for mobos with 440BX chipset - any suggestions where to start, tools needed? 😀

I was able to successfully add the PPro microcodes to the BIOS months ago, but sadly it didn't solve the issue of the BIOS freezing up just before printing the CPU ID text

Start reading at "experimental part".
It is somewhat processor register related. But obviously not impossible to fix, if someone is able to edit BIOS code.

My Tualatin Celeron shows up as a Pentium Pro in Dell's BIOS for my 440BX board. This is being accomplished through a Lin-Lin and Slotket adapter. I'd think it implies that the Pentium Pro microcode is in there. In my experience with BIOS hacking, many of them have microcodes for a range of processors you wouldn't expect to be there. The manufacturer BIOS for my Abit socket 478 board has microcode for several slot 1 processors, for example.

Sure they're slot 1? IIRC there was PIII mobiles in a 479 pin package that you could hack into certain 478 boards.

I know I've done weird crap though, like sticking PII microcode into a socket 7 board to see if a P-MMX gained any features.

There is a vogon member who would appear to have solved the BIOS problem, but he is keeping the secret and only releasing BIOS mods for those who purchase his reproduction slockets 😐

As he has absolutely EVERY right to do so.

Yea it would be nice to have everything done for free, but as I understand it, it take a bit of work to mod the bios correctly.

Yes and I have EVERY right to resent him for it

Keeping secrets is lame as fuck, it's not like I'm asking him to give the slockets away for free

Its his shit and expertise. He should be rewarded for it. It is just that simple.

No. I intend to modify some BIOSes myself and release them for free

More power to you. I'd be happy to help test on different boards, but thats as much as I can offer. I have no aptitude modifying bios'es
