Hello everyone!
So I've revived my first ever own PC which was Lucky Star 6LX2 with chipset i440LX-ITE-2A69JL1DC-00 which uses Award Bios 4.51PG.
Before updating BIOS with 9JD8-0A.bin I've patched it with 4.23 patch and updated bios with AWDFLASH55, from which it looks like it had patched it properly, but for some reasone I cannot use Windows XP when installing P3 CPU like Katmai &
Coppermine (P3 800 MHZ) in Slot 1. Like, it just hangs black screen or BSOD appears. OS installation won't boot after HDD check, even if I use empty hard drive. Some boot CD are working, like Acronis Disk Director, and FreeDos (which I used to patch & update bios). I've heard that you can install P3 CPU in that motherboard. Also, there is the message in POST which is being ignored: UNKNOWN CPU ID, MISSING MICRO CODE. I've tried to use P23MICRO.COD file (from rom.ru) while patching bios image, but still I've have same problem. When installing previous P2 CPU like Deschutes - it boot WinXP without any issues, but when I'am installing Pentium III 550 MHz Slot1 SL3F7 or Intel Pentium III 800 MHz Slot1 SL4BX - it wont boot OS.

Can some one help me identify what exactly I've messed up? That motherboard is pretty old, but stiil works fine with 320 RAM, still I wanted to use CPU with more instructions.

Or maybe after I've patched bios rom with 4.23 I should flash my Award bios to 4.23 version? It shows that it is using 4.51 version, still - bios were updated, but I still can see Model of Bios as 4.51PG ELITE BIOS
Or is it I just were that much dumb & incompetent with trying install P3 CPU which is not actually is supported by my motherboard?

Well, first of all, the board uses the 440LX chipset which - unlike the 440BX - does not support FSB speeds > 66 MHz.
To max out the board CPU-wise, you would probably have to go with Celeron CPUs (433 MHz Mendocino core for Slot 1, 733 MHz Coppermine-128 core if you use a slotket, preferably with adjustable VCore).
All Pentium III CPUs are either 100 or 133 MHz FSB, so if you get them to run at all, they won't run at full speed. If running anything newer than Katmai, you might also run into VCore problems because the board might not support other voltages than 2.0V.

Edit: Had a look at the manual, the BIOS seems to support raising (overclocking) the FSB to 75 MHz. Still, not full speed for any of the P3s or other FSB100 CPUs.

It is a known limitation of LX chipset: when installing a Coppermine CPU (doesn't matter whether it is PIII or Celeron) it gives BSOD with both XP and Windows 2000.

Many 3Dfx and Pentium III-S stuff.

Thank you! You were right, I've tried to install Pentium III E800 since thought it is Slot 1 & saw somewhere that I can try to run it with patched bios. It runs only as 500E Mhz if i set multiplyer to 8, and actually it is detected properly, without any UNKNOWN CPU ID error. Well, Bios works on all of CPU's I've tried so far, WinXP doesn't but - fair enough 😀
Slot 1 CPU are a wild thing to me. I probably should lower my expectations of turning my P2 into P3. I think i have slotket with socket 370, but dunno if it has adjustable Vcore. Well, this time I will be buying CPU for slotket and will try it out. Thanks again!

Thanks a lot! I didn't knew about that, thought I should try to reinstall OS in such case, but now it makes sense why installation of WinXP via CD even didn't started, but worked with FreeDOS & Acronis Disk Director boot CD without any issues. Maybe some Linux distro will works on it - I've managed to install Q4OS on Mitac-6133 last year, and that one runs really well for laptop with 192 MB of RAM, maybe I should try Puppy Linux or something.
