Ok, so, about the hard disks: I tried again this morning with all three and it works

. I did as you saidl, changed the jumpers from cable select to their appropriate positions, but it still won't boot from the smallest one(1 gb) the message I get is: Invalid system disk. Replace the disk, and then press any key. Anyway, that isn't a problem any more since i have access to 12 gb to boot from

.
The issue with the memory still bothers me though. I don't know the 32mb modules' brand but i know that all of them work because if I leave one of the pairs on the board and remove the other one it will recognize them. Another thing to note is that if I switch the pairs' order meaning the 16mb modules on the first bank and the 32mb modules on the other then it won't recognize the 32mb modules instead of the 16mb ones. I also tried this on another motherboard (Jetway's j-656c) and I get the same results, even though the manual clearly states that it supports up to 128mb and one doesn't need to change any jumpers.
As a side note, I don't have the manual for the kaimei motherboard but I would be very interested in reading it if anyone has it.
