Re: [PLUG] CDROM making me crazy
|
Did you set the CDROM back to the Master? Sometimes - when an IDE drive is
the only device on a bus - it doesn't even want to be jumpered as Master -
so I remove the jumper all together (or jumper it across the top pins of
master & slave).
Are you sure the cdrom modules are loading? lsmod results.
That is all I can think of right now.
