Question Missing CD-ROM

I'm using Mandrake 9.1, pentium II 450, BX motherboard. I have my drives (IDE all) setup like so:

Primary Master ==> Hard driver
Primary Slave ==> CD ROM
Secondary Master ==> CD Burner

I have recently upgraded from Mandrake 8.0, where everything worked fine. However, after upgrading to 9.1 and "devfs", my CD ROM does not work.

They used to be listed in /dev as

/dev/cdrom ==> CD ROM
/dev/cdrom2 ==> CD Burner

And the "fstab" entries still reflect this, they should be ok. However, my dev entries are now like so:

/dev/cdrom ==> /dev/cdroms/cdrom0 ==> /dev/scsi/host0/bus0/target0/lun0/cd

That's for the burner, and it is working fine.

/dev/hda ==> /dev/ide/host0/bus0/target0/lun0/disc

Which is also fine, it is working perfectly... Now if I understand this correctly, a CD ROM residing on the primary slave under devfs, should have an entry here:


However, it's not there... what I do have is an entry like so:


But I am guessing that is the burner...(as accoring to the path this is the secondary master)

When I open hard drake it reports both a CD Burner and a CD ROM, however, it states the correct "devfs" entry for the burner, and says the CD ROM is here:


Which of course it isn't because that entry doesn't exist. Harddrake also says that it's old /dev entry should be /dev/hdb. From what I know about "devfs" this entry should be maintained as a link to the above for compatibility, however, it is not there either. The only other "hd?" entry I have is "hdd" which is a link to:


Which again I'm guessing is the burner.

I believe what I need to do is get the "/dev/ide/host0/bus0/target1/lun0/cd" entry created for the CD ROM and then link /dev/cdrom2 to it. At that point "fstab" should properly mount everything (in reverse of what I had before but who cares...).

The thing is I have no idea on how to create this entry in "devfs" for my CD ROM.

Try mount /dev/hdb /mnt/cdrom. If it mount your cdrom, then change /dev/cdrom /dev/hdb. You could also make a symlink from /dev/cdrom to /dev/hdb.
