Re: Machine Check when booting dqa0?

Hi guys,
        All my drive problems went away when I used a different IDE cable.
Unfortunately, I only have one spare, non-pin-blocked IDE cable around, so
I'm running just the hard drive for now. FreeBSD booted just fine from the
IDE drive, though. When I round up another non-pin-blocked IDE cable I'm
certain the CD-ROM and second hard drive will show up without problem.
        The IDE performance on this PC164 leaves much to be desired. I'm
going to have to toss a SCSI card in this thing and just go SCSI.

Thanks,
Josh
