I too had problems when using Xcdroast , I solved them by makeing both my
regular CD and my Cd read-write scsi devices by using the ide-scsi driver.
one thing additional you got to do is , well realy two additional things ,
1. change the symbolic link in /dev for your regular cd and cd recorder
to the appropaite scsi device name , in my case it was /dev/scd0 and
/dev/scd1 for the two drives , and of course if your going to mount them at
boot time then change
2. /etc/fstab to reflect the new device's
that in addition to seting up modules.conf is all you need ,
From the doc's I read the lilo thing is optional , if you use modules it
has no effect , if you got ide compiled into the kernel then you need it to
tell the kernel not to grab the CD's, I just made an entry in modules.conf
fro both drives ...
now I can read from the regular CD and write the contents to the CD writter
with out having to copy anything onto my hard drive. Works great
Greg
