Just upgraded 2.4 to 2.6.12 kernel but my /dev folder doesn have entries for my CD or DVD drives:

Seems to be a hell of a lot thats missing. Ive tried playing around with psuedo filesystems and recompiling but no change it seems

Any ideas?

Is /etc/rc.d/rc.udev executable ?
Have you a /sys directory ?

Yes and Yes

Sys gives me:

block bus class devices firmware kernel module power

Maybe your CD is not being detected and that's why udev is not creating a device node for it.

is /etc/rc.d/rc.hotplug executable ?

Yes its excutable

what is the output of :

dmesg |grep CD

egag

hdc: SONY DVD-ROM DDU1612, ATAPI CD/DVD-ROM drive
hdd: CREATIVE CD-RW RW8435E, ATAPI CD/DVD-ROM drive

well... they are recognised by the kernel...?
could it be that you still have smth. in lilo.conf like :

append="hdd=ide-scsi"

and that causes trouble ?

egag

OK i solved it thanks for help - seems that compiling with IDE-CDROM in the kernel rather than as a module fixed it

For my part I have it as module (ide-cd) but I have to
explicitly indicate it in grub.conf, with hdc=ide-cd added
to the kernel line boot parameters

Thx will think about doing that
