kernel setup

The initial error was from xcdroast responds: "Failed to scan the SCSI-bus. Either no permission to access the generic scsi devices or no SCSI support enabled in the kernel. For ATAPI devices you have to install the SCSI-emulation first. See the CD-Writing-HOWTO how to do that."

kernel compilation:

• Y - SCSI emulation support (CONFIG_BLK_DEV_IDESCSI)
  
• Y - SCSI generic support (CONFIG_CHR_DEV_SG)
  
• Y - SCSI CD-ROM support (CONFIG_BLK_DEV_SR)
  
• SCSI support, SCSI CDROM support, Enable vendor-specific extensions, and SCSI generic support are all checked
• compiled new kernel and installed it in /boot

boot options

lilo.conf

• added to the new kernel's section append="hdc=ide-scsi" where /dev/hdc was the cdrom drive. I left the root device and HDDs as ide devices.

Under /dev/, the scd* entries refer to a scsi cdrom
sr does too
the major number is 11
256 SCSI cdroms are allowd

from that point on, cannot refer to it as /dev/hdc because now it's a scsi drive. For example, to mount you need to type sudo mount -t iso9660 /dev/scd0 /mnt/cdrom/ (don't need sudo if 'user' is in next to last column of /etc/fstab).

Problem once is that I made symlink from /dev/scd0 to /dev/hdc and that that won't work when the grub.conf is properly setup with the option

the cdrom was configured on reboot

title Red Hat Linux (2.4.18-14)
        root (hd0,4)
        kernel /boot/vmlinuz-2.4.18-14 ro root=LABEL=/ hdg=ide-scsi hdc=ide-scsi hdd=ide-scsi
        initrd /boot/initrd-2.4.18-14.img

so that the hdc is really ide-scsi. I need to replace that device file by making a new one.

burning

different programs, ways to burn:

1. entered xcdroast and saw my drive appear as scsi
2. did copying on the command line
3. burn an iso image as describe here.
4. cdrecord dev=0,0 cdimage.raw
   this will lead to permissions like root root r x r x r x
5. delete the iso cdimage from filesystem after verifying.

audio

went out and bought AUDIO cds which a nerd like myself, didn't have, i only had the data ones!

cdrecord -v speed=4 dev=0,1,0 -pad -audio -dummy *.wav

--> produced tracks with no sound, wrote "successfully".

2.6 kernel modifications

According to this link fedora and 2.6 can burn without loading the ide device as scsi
