scsi-emulation für ide-brenner, wofür!?
Hi, kann mir Jemand sagen wofür ich die scsi-emulation zum Betreiben eines IDE (ATAPI) - Brenners benötige oder wie bisher benötigt habe!? Dachte immer man kann nur so einen Brenner unter Linux ansteuern, hab nur jetzt festgestellt das es wohl auch mit den normalen IDE/ATAPI CDROM-Support geht! Im Beispiel habe ich so eine Audio-CD mit K3B gebrannt. Etwas stuzig macht mich allerdings das cdrecord -scanbus mir kein Device mehr anzeigt und ich mir nicht sicher bin ob das alles richtig funktionieren kann! Gruss Joerg _ Joerg Stadler Nettetal

Steve Doerr wrote I overlooked the SCSI cd support when I built my kernel. It's working perfectly now. I did almost the same thing on a system at work except I forgot the Generic SCSI support.

It complained that the device was missing /dev/sg0 cdrecord -scanbus told me to run cdrecord -scanbus, etc. I really felt stupid after discovering what I had done.

Steve Doerr [EMAIL PROTECTED] [2002-12-28 14:27:14 -0600]: I just installed and burned a cd per the cd writing howto, but now I can't find what to mount to read it. It's not at scd0 or scsi0 and I'm not sure how to find it. Run cdrecord -scanbus And post the output of that command. append=hdb=ide-scsi hdd=ide-scsi Since you had this in your lilo.conf it would seem to me that your cd would either be at /dev/scd1 or /dev/scd3 and could not be elsewhere. Since you tried /dev/scd1 try /dev/scd3 next. Does anyone know how to find it or see anything wrong with how I set this up? Here are my instructions for setting up a CD-RW drive on Debian. Perhaps they will help. This sets up a very particular configuration. You will have to adapt it for your installation. Bob Setting up a CD-RW drive I am going to assume that the CD-ROM is on a master IDE device and that the CD-RW is a slave IDE device on the same cable since that is a typical configuration. In order to use the CD writer it must appear as a SCSI device. In that case you might as well treat both of the devices as SCSI for consistency. First you need the kernel to load the ide-scsi module at boot time. Put the name of that driver in /etc/modules. In /etc/modules place the following: ide-scsi The ide-scsi module can only adapt an IDE device to a SCSI if it has not already been grabbed by the normal IDE layer. Therefore the kernel must be instructed to load the ide-scsi driver for these devices at boot time such that the ide-scsi driver will be loaded first. In /etc/lilo.conf place the following: append=hdc=ide-scsi hdd=ide-scsi The hdc device is your master device which I am assuming will be your CD-ROM device. The hdd device is your slave device which I am assuming will be your CD-RW device. Test your configuration using cdrecord -scanbus. It should be able to see your CD devices. cdrecord -scanbus At this point things are configured for the kernel to handle the devices correctly as SCSI devices. Now we set up the rest of the system to know about these. Typically on Linux systems the device is aliased as a symlink in /dev. Remove any previous aliases. Create new aliases for the new devices. rm -f /dev/cdrom ln -s /dev/scd0 /dev/cdrom rm -f /dev/cdrw ln -s /dev/scd1 /dev/cdrw Create mount points for these devices. These could go anywhere on your filesystem. Typically they will be mounted in / as /cdrom and /cdrw. However another common convention is to mount these under /mnt as /mnt/cdrom and /mnt/cdrw. For now I will go with the Debian default and show them in /cdrom and /cdrw. mkdir -p /cdrom /cdrw Configure those device nodes and mount points in your filesystem table so that they can be easily mounted. The configuration shown here allows any user to mount and unmount these devices as themself and root capability is not needed. In /etc/fstab place the following: /dev/cdrom /cdrom iso9660 ro,user,noauto 0 0 /dev/cdrw /cdrw iso9660 ro,user,noauto 0 0 All done! msg21317/pgp0.pgp Description: PGP signature

I assumed that if the ide-scsi was built as a module you would use options in the /etc/modutils setup to pass in the options when loading the module. I thought the append= line in lilo.conf was to pass in settings to compiled in code. Is that a wrong assumption? Another question: I have everything compiled into the kernel instead of as modules. I have two IDE drives and I'm *not* using the append line, yet the drives are still setup correctly as SCSI. Why don't I need the append= line? -- Bill Moseley [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
SCSI Emulation for IDE ???
Someone once mentioned to me that there was a package available that would configure an IDE device (i.e. CDROM) to appear as a SCSI device to the kernel - or at least any running applications If you know what this is, or where I can find more info on it, I would much appreciate it.

SCSI Emulation for IDE???
I too had faced this problem when I wanted to burn a cd on my ide cd-rw (hp7100i). One of the suggestions was to use a kernel later than 2.1.74. Since I could not compile the kernel 2.1.94 on my bo system, I compiled the 2.0.32 kernel with scsi emulation enabled. If you are planning to burn the cd's, you have to get cdrecord and apply the patch given therein.

Re: SCSI Emulation for IDE ???
One of the kernel options (for 2.0.33 at least) is SCSI-emulation support, and the help description sounds like it might be what you want. Look under Floppy, IDE, and other block devices when you generate your new kernel-configuration. I've not used it myself, so I can't really say how reliable it is...
