CDRW on IBM T23 with Gentoo
Didn't notice until now that my CD-RW/DVD player wasn't loading properly – you can tell how much I use it, eh?
I'd already built the kernel with the correct SCSI modules (see references, below). I'd also already added
"hdc=ide-scsi" to my grub boot parameters.
What was left was the following:
# Give the cdrw group write permissions to /dev/sg0 # This is done to have non root user use the burner (scan the scsi bus) REGISTER ^scsi/host.*/bus.*/target.*/lun.*/generic PERMISSIONS root.cdrw 660
- commented out:
# Create /dev/cdrom for the first cdrom drive #LOOKUP ^cdrom$ CFUNCTION GLOBAL mksymlink cdroms/cdrom0 cdrom #REGISTER ^cdroms/cdrom0$ CFUNCTION GLOBAL mksymlink $devname cdrom #UNREGISTER ^cdroms/cdrom0$ CFUNCTION GLOBAL unlink cdrom
- uncommented the following:
# Create /dev/cdrw for the first cdrom on the scsi bus # (change ‘sr0' to suite your setup) LOOKUP ^cdrw$ CFUNCTION GLOBAL mksymlink sr0 cdrw REGISTER ^sr0$ CFUNCTION GLOBAL mksymlink $devname cdrw UNREGISTER ^sr0$ CFUNCTION GLOBAL unlink cdrw
