Is it being probed as mcd0 or mcd1?  I seem to remember leaving the device
files for /dev/mcd1a off the boot floppy due to a critical inode shortage,
in which case you'll definitely want this to probe as mcd0 instead for the
install (for the actual *runtime* of the OS this wouldn't matter, but for
the installation the CD you're using it kinda has to be `cd0').

Fortunately, this is very easy.  Boot with -c again (remember to do all of
the following twice - once at floppy boot time, and again when it boots
off the hard disk) and do this:

config> irq mcd0 11
config> port mcd0 0x340
config> disable mcd1
config> quit

After this, you'll not need to do anything more.  Typing `mount /cdrom'
(as root) whenever you bring your system up will mount whichever CD
is in the drive.
