Hello everyone!

I've got this dual slot1/socket370 board and it works really well with both a katmai p3 (450mhz) on the slot1 and both a celeron 433 and later p3 800eb. except... when i chanche the fsb on the bios from 66mhz to anything above. for some reason, everything works except the usb ports. even at 100mhz and not 133. also. the vga looked a bit weird the first days but now it seems ok.

i'm thinking for some reason the usb controller is tied to pci so maybe it's set to be half of the front side bus so 66/2 but when i raise it to 100 or 133 it doesn't work because it's clocked too high. but this is just speculation. i've tried to load ths bios in the ami bios editor to search a clock adjusting setting but i haven't found it yet.

the ram is 133mhz as well but i should have some slower sticks.

i've also got available a post card, a soundblaster live and a s3 trio64v2dx, which all work on this board.

maybe it's something silly i'm missing but this is the oldest board i've got and it's a few years older than myself so please forgive my ignorance.

thanks in advance!
