sata cd-rom not being recognised???

atom · 01-27-2005, 03:32 AM

Ok, here's the thing.

I installed gentoo with SATA being in legacy mode, so that way, /dev/hda,b,c and /dev/cdrom worked NP.

I recently switched from legacy mode to real sata mode, got my kernel to boot of /dev/sda5 and changed all the required disks. The problem is, i can't find my cd-rom. It's not /dev/cdrom, and a /dev/scd entry does not exist.

help?

p.s.: kernel recompiles are no big deal, i might have excluded the drivers. I have almost everything under scsi included in, but i will check again using xconfig.

From my experience with SATA, your cdrom is probably listed as /dev/sd? or something similar. I know that on a regular system, my cdrom is listed as /dev/hdc with a link pointing to it from /dev/cdrom

dude, i have this listed on /dev:

sda
sdb
sdc

and they are all HD's. My cdrom isn't even there. It isn't even in the scsi folder (it contains host0 host2 and host3). The cdrom is the primary slave (meaning it's supposed to be host0 but it doesn't show up. It works normally under windows (dualboot))

I'm sorry but your solution would be nice if the cdrom got recognised in the 1st place...

Thank you anyway, i appreciate it.

in order for ATAPI over SATA to work in linux, you need to use kernel 2.6.10 (or newer, i guess) and change the line in include/linux/libata.h

#undef ATA_ENABLE_ATAPI

to

#define ATA_ENABLE_ATAPI

then rebuild the kernel, and it should work.

(it then shows up as sr0 on my system. not sure why!)
