cdrom doesnt work.

[vhg119]

i cant get my cdrom working. it cannot mount.
i tried linking /dev/cdrom to /dev/hde but it does not work.

specs: Redhat 7.1
comp: sony vaio pcg-z505he
sony pccard cdrom - pcga-cd51.

my line in fstab: /dev/cdrom /mnt/cdrom iso9660 noauto, user 0 0

but when i try to mount it, it keeps saying "/dev/cdrom is not a valid block device"

what the heck is going on?

i've read some sites online and it says that the cdrom is on /dev/hde.

possible culprit:

i just upgraded my "stock" kernel to 2.4.12 but with the same settings except some changed to get my memory stick support.:

CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y

CONFIG_USB_STORAGE=y

and the memory stick is on /dev/sda1

I searched Google for this and it looks like the cdrom isn't automatically detected. This is for a laptop, right? Some things to try are :

Typing 'linux ide2=0x180,0x386' at the boot prompt
Turning off APCI in the BIOS
Turning off PNP in the BIOS

Is there any way of loading those options as modules instead of recompiling the kernel? I have a sony Vaio with the memory stick drive and all of its components within the case... but it seems that what you did would solve my problems instantaneously. but recomplining the kernel has never worked well for me... i guess i'm hoping for a way around that :)

thanks
