i was able to use xcdroast before with redhat v9 but now that i just installed fedora core 3 it's giving me this error:

No CD-Writer or CD-ROM device detected.
For ATAPI/IDE devices under Linux you have to enable
SCSI-Emulation in the kernel in order to activate them.

version info:
xcdroast: .98alpha15
kernel: 2.6.9-1.667

i've spent a few hours already on searching google & LQ for this, and will continue slogging my way throught the myriad of posts on the subject, however, if anyone knows the solution to this problem it would save me a lot of time and i would be greatly appreciative.

so far, i've tried setting the kernel option hdc=ide-scs to enable scsi emulation which makes the drive /dev/scd0 instead of /dev/hdc. i've tried to enter both into xcdroast setup (manually add device option), neither works.

i don't know if i have to do the insmods (from the faq)

/sbin/insmod ide-scsi; /sbin/insmod sg

i tried that and got:
nsmod: can't read 'ide-scsi': No such file or directory
insmod: can't read 'sg': No such file or directory

i did a locate on ide-scsi and got:
/lib/modules/2.6.9-1.667/kernel/drivers/scsi/ide-scsi.ko

there's also a sg.ko in that directory, but i don't know what this means. how can i tell if the scsi modules are loaded?

U tried to update to fc3 i686 681? thats what fixed it on mine but I do have a Virtual dual cpu, It says it should work on single cpu anyhow

MaChew,

i see there are updates 678 & 681 out there. i've never done a kernel update before, do i have to apply both or are they cumulative such that i can apply just 681? is your xcdroast working with ide or scsi emulation?

ok, i found the problem. there has to be a cd in the drive before it will detect it (the drive that is). this falls into the category of "never overlook the obvious", which i obviously did. however, in my defense i will say that since i was only testing to see if xcdroast was going to work after the upgrade (and had no intention of actually burning a cd) there didn't seem to be a need to put a cd in. i should also point out that it is not necessarily sensical that a blank cd should make the drive any more capable of making itself known to the application than it was without, but i digress...

in an effort to make this thread useful to anyone else that may have the same problem i did, let me say that adding the "hdc=ide-scs" to /etc/grub.conf was the solution to the original problem (i tried it again without that option, this time with a cd in the drive, and it was still not able to detect the drive). so the scsi emulation is necessary for xcdroast.

i also noticed upon inserting a blank cd that a window labeled "CD/DVD Creator" came up which appears to be a built-in method of burning cd's. i did a help on it to see what the program was but it appears to be part of nautilus. i may try to use it the next time i need to burn a cd and would be interested to know if anyone else has used it and what their experience was.
