Hi again !!
I've received some SIMM modules and 486 CPUs yesterday. Now I can answer my previous questions (and not speculate as we have done here, until now):
1- The mainboard supports modules SIMMs greater of 16 MBs. At this moment the board for testing purpose has
SIMM 0: 32 MB
SIMM 1: 32 MB
SIMM 2: 16 MB
SIMM 3: empty
and it's working properly.
2.- I've tested 4 diferents 486 CPUs: DX-33, SX-25, DX2-50 and DX2-66. The BIOS detects right, without any problems. I read the manual again and the manual does not make references to support SX2 CPUs: only SX, DX, DX2 and DX4 CPUs. This statement is wrong:
I would almost bet that the Bios was intentionally set up to defraud people by selling them a 486 as a Pentium.
basically, I suspect that the CPU type will always be shown as a P54CM regardless of what CPU is actually used.
I understand that board BIOS doesn't support for SX2 CPUs, but they are working properly if you configure like SX CPU
3. The cache is fake. I've tested with phil's DOS benchmarks
4.- Perfomance: I've read in some posts here that the perfmance of this board is poor if you compare with others: MSI...I've got a MSI board (Some questions about MS-4144). I haven't got much free time but, I've pass all test availabel in phil's DOS benchmarks. (the same configuration: identical CPU, identical VGA (matrox millennium II 8 MB - PCI, identical memory modules, and identical HD (Compact flash) ). Well, I'm very surpraise. The PCChips with fake cache outperforms my MSI-4144 in all phil tests. I understand that are very simple tests, but....It's very curious
