Two CDROM drives and module compilation of CDROM Support

Two CDROM drives and module compilation of CDROM Support

[Little Djo]

Hi,

if I build CDROM support as module, then work only first CDROM (hdc):
[root]# modprobe ide-cd
[root]# dmesg | tail -3
ide-cd: ignoring drive hdd
hdc: ATAPI 52X CD-ROM CD-R/RW drive, 2048kB Cache, UDMA(33)
Uniform CD-ROM driver Revision: 3.12

if i compile CDROM support in kernel, all two drives work!

this feature present in kernel 2.6.0 (-test## also), 2.6.1, 2.6.1-mm1,
but don't present in kernel 2.4.x

Most likely you have an entry in /etc/modules.conf ala

options ide-cd ignore=hdd

so ide-cd discards hdd (maybe you used to drive it with ide-scsi?)
