Hello,

Do you compile the kernel with the current filesystem? I have on the second partition minixfs.

Greetings
Ulrich Radig

P.S: If you have 15ns RAM you can edit the waitstates in the Bootloader. The speed is very low (0.81 BogoMips)

Hi Ulrich
Thanx for your reply,
Can you tell me the BCFG registers settings in the bootloader?
