I have a DEC Alpha running current and I have an ultra disk
on an adaptec2940uw that is configured as a fast drive (10mhz)

I changed the line in ahc_pci.c that says:
ahc->type &= ~AHC_ULTRA;
to:
;

compiled a new kernel and booted... everything seemed find and
the disk appeard to be config'd to 20mhz...

anyway a few days later (today) the system just rebooted... (nothing in the
logs)
so anyway I will wait and see if it happens again, but was it just plain
stupid to try that little hack?

Thanks,
Nick Maniscalco
