I've tried two different Western Digitals and a Fujitsu. If I make the hard drive the primary master it shows up as dqa0, but the CDROM doesn't show up (set to primary slave or secondary master). If the CDROm is primary master, it becomes dqa0. Basically, it only finds the primary master (dqa0) no matter what the device type is. Additionally, if I make the CDROM dqa0 and boot my Tru64 CD on it, it gets as far as jumping to the installer (video mode toggles to an ISO font) and the kernel panics. I don't recall if SRM interprets it as a machine check or not. This machine used to be an NT box with ARC and a non-SRM SCSI controller. It runs Linux fine (booted from the IDE HDD as dqa0) and once the Linux kernel boots, it finds the CDROM drive that should have been dqb0, but isn't. I booted from a Linux floppy (dva0) in order to do a CDROM install. I'm going to try a different Symbios SCSI card tonight and see if SRM likes it, because I'd rather do FreeBSD or Tru64 on it, and the CMD-whatever IDE controller basically sucks anyway. All this reminds me of an elderly Ultrix DECstation 3100 we had to take care of where the drives had to be spun up in just the right order to show up.. *sighs* -- Jameel Akari > > > > > > > Hi Andrew, > > > > I tried booting from IDE immediately after the power-on, but got > > > > the same result every time I tried. > > > > The exact machine error is a "660 Machine Check," which from my > > > > searching indicates a memory error.
