I find that rather difficult to believe. By default, there will be some
symbolic links (/dev/cdrom, /dev/cdrecorder, /dev/dvd, /dev/dvdwriter
and so on) against the raw devices. Assuming the raw devices are IDE,
then the devices are:
/dev/hda First IDE, primary drive
/dev/hdb First IDE, secondary drive
/dev/hdc Second IDE, primary drive
/dev/hdd Second IDE, secondary drive
Note that most of this is handled via udev and not a kernel probe as it
was in V2.4 kernels and may not show up in dmesg.
Another place to look is in /proc. You should see entries in /proc/ide
in there for them. For example:
[root@(protected) ide]# ls /proc/ide
ali drivers hda hdc ide0 ide1
[root@(protected) ide]# cat /proc/ide/hdc/model
TOSHIBA DVD-ROM SD-R6012
So, I have a Toshiba DVD-ROM (actually a DVD+-RW) as /dev/hdc.
