Has anyone had any luck getting 1 MB of L2 cache working in a Shuttle HOT-433 ver 1-3?
I seem to be striking out. When 1024 KB cache is in stalled With the latest AMI BIOS, I cannot POST.
With AWARD BIOS, I can POST, diskette boot, and it even pass a 4 hr test with Memtest, however CTCM shows weird stuff. Under the L2 cache section, CTCM says "not found or not active or more than 8 times associative." CTCM7 claims "Discrepancy in cache measurement" and lists the L2 cache amount as "2048 KByte, associativity not determinable." Under the Cacheable Area L2, it lists "127 MByte, Cache Area." Cachechk correctly shows a different speed for the the 16KB-1024KB section of memory.
Unfortunately, the AWARD BIOS may have some issues with bus mastering because I cannot boot with the SCSI harddrive/controller into Win98/NT4 -- it goes all wonky at boot and gets hung up on the SCSI DVD-ROM.
With 512KB double banked cache, AMI BIOS works fine with a Cyrix 5x86-120 and Intel DX4-120, and with the AWARD (or AMI) BIOS, 512 KB shows correctly in CTCM. I can run Win98SE without issue. Still can't SCSI boot from the AWARD BIOS though.
I've tried all different cache timings, different RAM timings, swapped EDO and FPM RAM, tested different CPUs, removed all but the video card, tryed 512K and 256K TAGs, write-back, write-through, 7+1 Bits and 8+0 Bits for Alt Bit in Tag SRAM, etc. The 1 MB cache modules works fine in 512 KB single banked mode, so I do not think the cache is at fault. I wonder if the HOT-433 manual has the incorrect jumpers specified for 1 MB cache?
I can still set the 512 KB L2 cache to Write-thru mode and cache up to 128 MB of RAM, but I was hoping for write-back mode.
Also, the HOT-433 AWARD BIOS doesn't seem to work well with my AMD X5-133 -- cannot POST.
Any other ideas on what to test to get 1 MB cache working? Has anyone been successful with this?
