Hello,
I've got a Coppermine Celeron (566MHz) FCPGA processor in a PCChips M767V board using a Slot 1 to Socket 370 converter (slocket). Yes, I know - shame on me for using a PCChips motherboard It's the only available motherboard I have at the moment.
The board boots up fine (recognizing the chip as a "Pentium III 600MHz") and boots into Windows fine. Except, the L2 cache is disabled for some strange reason! (only the 32KB L1 cache is "reported")
I thought this might be because it's a slightly older board, so I found the latest BIOS for it (dated 04/02/99) and flashed it - no difference. Apparently the "great" fellows at PCChips didn't bother to add Cu-mine support in the BIOS
Is there anything I can do here, other than finding a different motherboard? I've looked through the CMOS setup menu just in case and have not found a "L2 Cache Disable" setting There were no problems with an older 400MHz P2 Celeron processor.
Help!
Cu-mine Celeron 566 in PCChips M767V -> L2 cache disabled
This calls for checkup5:

In the case of AMI BIOSes, there's no other alternative.

Thanks for the link. Let me see if I understand it right: I have to use the utility checkup5.exe to upgrade the CPU errata microcode stored in the BIOS. All I have to do to perform this is run checkup5.exe in a clean DOS enviroment?

Are you sure I need to use that file? I glanced at the readme for checkup5.exe and it said the external database was no longer required because the latest version is included in the executable.

Checkup5 ran fine and applied a revision update, but it didn't help my problem. 32KB is still the reported size of my cache.
Maybe my motherboard just doesn't like CuMine processors?

A thought: Is it possible that the L2 cache is actually being used, but just not reported? The computer seems to run fast enough (not much HD swapfile activity w/ 192MB of RAM). If the L2 cache was *really* disabled, how noticeable would the slowdown be?

Try CPU-Z and/or AIDA32
They might show L2-Cach enabled or disabled
I have a small old DOS-program checking memory activity and it will give out a graph .
You should see a drop at 32K and at 128K if L1/L2 are anabled and only at 32K if L2 is disabled

Denniss - I have that program...cachegraf. The graphing is pretty cool.
You can also use cachechk or maybe ctcm, etc...
