"secondary master" means that it's the master device on the second IDE chain. on your average pc these days you have two IDE controllers, each allowing for a master and slave device, giving you a total of four IDE devices. usually iirc the master is hda and hdc and the slaves are
hdb and hdd for the respective ide chains 1 and 2. I guess it's moot
now, but if you find yourself in that situation again, take a look
to see if the cdrom drives still exist as hd[a-d]. if you don't know
which is which, put an iso cd in the drive in question and do
file -s /dev/hda[a-d]
and something should show up about an iso filesystem, or at least 'data'
on the drive with the cd in it. actually, trying this out myself now,
if i put the cd in the tray and leave the tray out, and do the command,
it will actually pull the cd in to read it when i file -s it.
