Need to find a BIOS update for a mystery mobo

The board is stamped KL97-XV. According to the web searches I've done, it's an OEM board made by Asus for HP.

It's a Slot 1 LX board with on-board ATI video. It's supposed to have a full range of bus speeds up to 83MHz, but I'm not sure of the jumper settings; can't find anything on Asus' site.

I'd like to stick a PPGA Celeron 533A into a slotket and kick it up to 8x75 or so; it's a fast, stable system with only a Celeron 266, but it suuuuure cracks SETI slow. 😉
 
Ah....ASUS OEM motherboards.

You see, the problem with these boards is that ASUS ONLY provides support for their retail boards, and refuse to talk to you if you have an OEM motherboard. No support in any form is offered for OEM boards, so you won't be able to find a BIOS for it from ASUS.

You will have to check back with the system manufacturer that the board came out of in order to get a new BIOS.
 
Ah, ok. It came out of a Pavilion 8250. Looking on HP's site now . . .

A PPGA Celeron 533 should work even without BIOS support, right? Isn't BIOS support usually so the speed displays properly at boot up? If the multiplier is hard locked, it should just be plug and play . . .or am I wrong?
 
A PPGA Celeron 533 will work as long as there is BIOS support for the PPGA 300A, since they are the same stepping (CPUID:0665).

BIOS support for steppings is needed so that that BIOS can identify the processor, and load the necessary microcode: performance enhancing settings, switches and bug patches.

You are correct in that simply plugging in the processor would work, as the multiplier is locked, and ASUS BIOSes have always been smart enough to display speeds correctly.
 
Andy,

Yeah, the new BIOS I found added Celeron support. Before it told me that the CPU was a P2 266. Now it says Celeron 266. I know 533 is the highest I can go because the 566 and up are FC-PGA and don't work on the newest stuff. Also the computer properly recognizes my HD and CD-ROM now, which is kinda handy. 😉
 
There are 3 Celeron steppings: the Covington (Deschutes core without L2 cache, 065x), the original Mendocino Slot 1 stepping (0660) and the PPGA Celeron Mendocino (0665).

Even if "Celeron support" was added, it may not support the 066x steppings.

An FC-PGA Celeron exists at 533, known as the 533A.
 
According to the E-mail I got from HP tech support, the board will work with PPGA processors up to 533 (he said only slot processors, but a slotket would do the trick) but not FC-PGA.
