Hello there. My system specs are:
Shuttle HOT 649A DUAL SLot 1 BX
2 x Celeron 333A's (step code 665, mb0)
1 x PC133 Micron Cas 2 ram.
1 x Inno3d GeForce 2 GTS 64mb DDR
Running Win XP rev 2600
This requires a lengthy explanation.
#1 I am an electrical engineer, and have no problem with technical fixes.
The problem is:
I bought 2 x P3 1000EB (Step Code SLC48 686 08)'s
to use in my system. The main board only supports up to early pentium 3 katmai's. I personally updated the Bios Stepcode information so it now supposedly supports Coppermines, and Tualatins. I bought 2 x PL-iP3/T's from Powerleap. These are socket 370 to slot 1 converter cards. Powerleap sent me 2x Celeron 2 1.2Ghz by accident (they didn't bill me [yet].)
1 Celeron 2 will work perfectly (the mod for dual Celeron 2s haven't been figured out yet.) HOWEVER, when I add either 1 or 2 of the coppermine Pentium 3's my system crashes at startup, or in safe mode, it hangs at AGP440.sys. It should be noted that by booting from the WIN XP CD, I can get to the repair console.
The things I have tried but didn't work:

1) Formatting the harddrive and re-installing Win Xp. The system would crash during the Re-install, every single time.
2) under clocking theprocessors to 100MHz FSB.
I even tried 66MHz FSB, it still had the same hang up.
3) Swapping my AGP video card for a PCI one, then renaming AGP440.SYS.
The system would crash while loading a different driver at startup.
4) Running the system with ONLY a harddrive and the video card.
5) Switching to MPS Ver 1.1 & at 1.4, neither fixed it.

Win 95 boot disks work properly. This may be a Win XP problem, not a hardware problem. Intel's CPU ID boot disk utility correctly identifies the processors.

Occaisionally I get some errors, I've seen IRQ_NOT_LESS_THAN_OR_EQUAL_TO
BAD_SYSTEM_CONFIG_INFO
and a few others, the windows STOP site offers NO HELP.

It should be noted that the system WORKS PERFECTLY FINE with either the celeron 333a's or the Celeron Tualatin's. I updated the BIOS with AWDFLASH 7.53 to add the extra CPU micro codes from intel's own PEP.DAT file, which contains the micro code for ALL P2-CEL1, P3-CEL2, P3/T, CEL/T. If ANYONE out there uses a P3 Coppermine CPU, please tell me what Reg Keys you have set for AGP440.SYS, I'd love to compare them to mine.

Ok you have a problem with the cocntroller, you need dowload the proper driver for you videocard, if you are use the windows xp you need download the driver for your videocard on format to windows xp

Since I posted, I went out and bought a new motherboard, and ECS D6VAA Dual Socket 370 board. unfortunately , one of my CPUs has been broken all along. AC Micro refuses to replace my one dead CPU, and I'm furious. The CPU would POST, and get up to win xp then crash, every single time, in 2 differnet motherboards, and in multiple configurations of hardware. THE ONLY REASON MY COMPUTER WORKED IN DOS, WAS BECAUSE THE BAD CPU WAS IN SOCKET 2, AND WASN'T BEING ACCESSED. The motherboard recognizes that there is a CPU on boot up, but it's up to the operating system to actually send it numbers to crunch. AC Micro's return policy is 30 days for OEM CPUs, I took 72. I told them that I had to test the CPU on 2 motherboards, because I couldn't figure out what was wrong.

The guys @ Powerleap thought it was great that I was editing the BIOS and trying EVERYTHING to get the CPUs to work in my Dual BX board, and they EVEN EXTENDED my already late warranty. The tech there just said: Keep on trying, when you run out of ideas, then you can return the adapters for a refund. Those guys are very professional in my mind. AC Micro on the other hand needs to ease up on their RMA policies. I bought a DEAD CPU. I paid for a working one. Where's the DAMN LEMON LAWS FOR CPUS?! So now I'm out $300.
You may ask, why did you wait so long? Well, AC Micro has a 20% restocking fee for all returned parts that are working. If i wanted my money back, and it turned out that the CPUs were ok, i'd have to pay a 40% restocking fee. that's 120$ US. There's no way i'm going to fork over that much money because I didn't properly test the CPUs. I spent 1 month testing each motherboard + hardware, + various drivers.

bottom line, I feel I got screwed big time.
I will NEVER BUY FROM AC MICRO AGAIN.
