ATAPI-SCSI emulation

Erik-joix · #1 7th May 2004, 03:37 AM

Does someone know how to enable that for a CD/DVD burner?
I tried this in grub.conf but it didnt work.

Code:

kernel /vmlinuz-2.6.5-1.351 ro root=LABEL=/ hdd=ide-scsi rhgb quiet

Also "ls -l /dev/cdrom" returns this.
lrwxrwxrwx 1 root root 8 Apr 30 01:00 /dev/cdrom -> /dev/hdd

Edit:
I tried the search function but it didn't return anything.
Edit #2:
I tried to manually load modules. When i tried cdrom and ide_scsi did i get following.

Code:

[root@localhost root]# modprobe cdrom
FATAL: Module cdrom not found.

and

Code:

[root@localhost root]# modprobe ide-scsi
FATAL: Module ide_scsi not found.

lsmod returns this

Code:

I believe the ide-scsi driver was removed from 2.6 becuse Linus never liked it and thought it was "hacky and inelegant." I seem to remember there was quite a row over this between the kernel hackers and the cdrecord project...

Erik-joix · #3 7th May 2004, 04:46 AM

So could this mean i wouldn't be able to burn DVD's since K3B and/or X-CD-Roast require this emulation or is there something else?

Darkmage · #4 7th May 2004, 05:09 AM

what is the output of

Code:

ls -la /dev/cd*

Erik-joix · #5 7th May 2004, 05:59 AM

Code:

Darkmage · #6 7th May 2004, 06:35 AM

Code:

kernel /vmlinuz-2.6.5-1.351 ro root=LABEL=/ hdd=ide-scsi rhgb quiet

remove hdd=ide-scsi from grub.conf and reboot
At a shell what is the output of

Code:

cdrecord -scanbus

Trying to see if it is any different from the one you posted before.

kai_t · #7 7th May 2004, 10:24 PM

Use cdrecord dev=ATAPI: -scanbus to list all ATAPI devices.

You should be able to specify the device using e.g. dev=ATAPI:0,0,0 or dev=/dev/hdd.

cdrdao supports non-SCSI-emulated ATAPI devices as of version 1.1.8.

Erik-joix · #8 8th May 2004, 05:08 AM

I removed hdd=ide-scsi from grub.conf and rebooted. The output of "cdrecord -scanbus" is now this.

To burn DVD's?

Darkmage · #10 8th May 2004, 09:49 AM

To burn a DVD I use K3b in kde but, I am not sure about gnome

trufflesdad · #11 8th May 2004, 09:59 AM

I had exactly this problem and after a lot of editing I find I have to enter into grub
as so after the kernel call...root=LABEL=/ ide-scsi rhgb quiet

This rips a cd ok but as yet not tried a burn....

Ted

Can you burn DVD's this way and are you sure that line is correct?

trufflesdad · #14 8th May 2004, 05:42 PM

Before I edited the line I had the same results as you but after the edit 2 cd icons
showed up on the toolbar and I was able to rip a cd and play a cd...I would only take a minute for you to edit menu.lst reboot and find out what happens...

I'm not quite getting why i should do this.
Where's this "menu.lst" file and what's it for?
