Re: Desperate after upgrading OBP from 3.11 to 3.31

["A. Eijkhoudt" <penguin@dhcp.net>]

Hi Ben,

Thanks for responding. I have, but to no avail. I've tried running SILO 
with multiple exotic combinations such as -f and -u to force it to 
rewrite the bootblock for my Ultra. What I don't understand is how the 
boot sector could get corrupted in the first place. I've also tried 
putting the first partition back at 'Start = 0' now; no deal.

Kind regards,

Arnim
