Can anyone please explain how to have normal CD-Rom & DVD as well as the scsi emulation.
I have a section in devfsd.conf for cdrom0 and cdrom1 also sections for sg0 and sg1. In Xcdroast the DVD Drive and Plextor Drives show up ok, but I now cannot play audio cds with KsCD. and wouldn't be able to play DVDs either. I put DVD as sg1 in scsi part so that I would be able to copy cd's if required. In /dev/cdroms nothing shows, and in /ide/host0/bus1/target1/lun/0/ -----no cd.

Make sure you have SCSI CD-ROM support compiled into the kernel or as a module and loaded.
To check if scsi cdrom support is enabled:
| Code: | cat /proc/devices
Character devices:
.....
Block devices:
2 fd
3 ide0
11 sr
22 ide1
|
Make sure sr appears there.
Otherwise,
Do you have both scsi emulation and atapi cd compiled into the kernel ?
If so you need to telll the kernel to treat the cd/dvd devices as scsi.
here's my grub line:
| Code: | | kernel /boot/bzImage root=/dev/hdb1 hdc=scsi vga=0x305 |

think you mean hdc=ide-scsi (well that's what I use). You can still use /mnt/cdrom (mine routes to /scsi/host0....) to mount your cds, cdrecord requires the scsi-emulation (/dev/sg0 /dev/sr0) to write disks.
cat /proc/devices:
| Quote: |
char
21 sg
block
11 sr
|
Have you checked the /etc/devfsd.conf file? Well probably something to do with the cd player ksCD (I don't have this).
Sry can't help, lX

Possible. I think both'll work (at least here).

This is the result for cat /proc/devices:
Character devices:
1 mem
2 pty/m%d
3 pty/s%d
4 tts/%d
5 cua/%d
6 lp
7 vcs
10 misc
13 input
14 sound
21 sg
81 video_capture
108 ppp
128 ptm
136 pts/%d
162 raw
180 usb
Block devices:
2 fd
3 ide0
22 ide1

No 11 sr.
The scsi part is not the problem though. Although I haven't actually tried to burn anything with Xcdroast - the program is reading from both Plextor CDRW drive and the DVD drive. When I try to open KsCD -(CD Player) it says "no matching freedb entry found"
I was able to use this program previously, before I recompiled to allow for scsi emulation, and I booted with an old kernel and it was working with it.
I'm going to have to recompile again anyway to try and get alsa working and a couple of other things, so I'll see what happens.
If I try to /mnt/crom0 - it says /dev/cdrom is not a block device, same for /dev/dvd & cdrom1

Well I recompiled and changed a few things, so I don't know which did the trick, but I now can access my CD-Rom for audio again.
