SCSI emulated drives back to IDE
Hello
I would like to return my ide drives (dvd and dvdram drives) back to atapi.
The first thing that I did was to remove devfs=mount hdc=ide-scsi
hdd=ide-scsi from lilo.conf. After booting, Mandrake 10.0 cannot assign any
device to the drives.
Then I did:
a) I've checked Mandrake control center for dvd drivers. What follows is what
MCC shows:
Model: DVD-ROM ATAPIModel DVD-106S 012
Vendor: Pioneer
Bus: ide
Channel: secondary
New devfs device: /dev/ide/host0/bus1/target0/lun0/cd
Old device file: /dev/hdc
Media class: cdrom
us: ide
Channel: secondary
New devfs device: /dev/ide/host0/bus1/target1/lun0/cd
Old device file: /dev/hdd
Media class: cdrom
Of course the drivers don´t work. So I did (I have to mkdir bus1/target ....)
cd /dev/ide/host0/bus1/target0/lun0/
mknod -m 660 cd b 22 0
cd /dev/ide/host0/bus1/target1/lun0/
mknod -m 660 cd b 22 64
cd /dev
ln -s /dev/ide/host0/bus1/target0/lun0/cd hdc
ln -s /dev/ide/host0/bus1/target1/lun0/cd hdd
ln -s hdc cdrom
ln -s hdd cdrom1
It didn´t work either
dmesg shows me
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hdc: Pioneer DVD-ROM ATAPIModel DVD-106S 012, ATAPI CD/DVD-ROM drive
hdd: HL-DT-ST DVDRAM GSA-4120B, ATAPI CD/DVD-ROM drive
and
ide-cd: Unknown parameter `hdd''
ide-cd: Unknown parameter `hdd''
ide-cd: Unknown parameter `hdd''
ide-cd: Unknown parameter `hdd''
ide-cd: Unknown parameter `hdd''
ide-cd: Unknown parameter `hdd''
ide-cd: Unknown parameter `hdd''
ide-cd: Unknown parameter `hdd''
when I try eject any of the above devides, the system returns:
eject /dev/cdrom
eject: unable to open `/dev/ide/host0/bus1/target0/lun0/cd'
As for /dev/sr1 and /dev/sr0, this is message
ject /dev/sr0
eject: unable to find or open device for: `/dev/sr0'
What did I do wrong?
Many thanks
Ed
