How do I enable SCSI Emulation?

enigma Z · 09-08-2003, 10:15 AM

Hey, How do I enable SCSI emulation on an ordinary CD drive?? I have a burner that Mandrake automatically enables it on, but how do I do it with something that doesn't have it already?? I'd like to do this because Xcdroast, and Grip don't recognise my CD player as something to read from if it isn't SCSI emulated.

Easy - edit /etc/lilo.conf to look something like this -

label="linux"
root=/dev/hda1
initrd=/boot/initrd.img
append="quiet noapic devfs=mount hdc=ide-scsi hdd=ide-scsi acpi=off"
vga=788
read-only

This is for my default boot item.
The stuff in red tells the kernel to access my secondary master -hdc and sec slave -hdd as scsi devices. (hda=primary master hdb=pri slave). Just put the relevant line into your file, save it, and as root, type lilo in a console to activate the changes. After a reboot, type cdrecord -scanbus as root in a console and you should see both your drives.

Hey, thanks, but what about xcdroast??

No problems. xcdroast it just a GUI frontend for cdrecord.

Oh OK!! THanks SOOOOO Much!!!

Hey, I did what you said, but Xcdroast didn't detect my DVD/CD reader to copy cd's from

Did cdrecord --scanbus show both devices?

enigma Z · 09-10-2003, 09:37 AM

No, but one of them isn't a burner.

Did you type lilo in a console, as root, to activate the changes?
(cdrecord - scanbus doesn't just show burners, it shows all devices addressed as scsi devices).

No, was I supposed to??

(I'm new at this)

OK, I'll try that.

Yes, I refer you to my first answer -

Oops, sorry.

BTW, does anyone know what the other things after the Append= mean??

aaa · 09-11-2003, 12:01 PM

They're a few other kernel options. For example, "acpi=off' turns off acpi support.
