Linux cannot access the optical drive on the Marquis C515
The stock Fedora Core and RHEL4/CentOS 4.x kernels do not recognize the onboard Marvell IDE controller.
In order to access the IDE controller, the following kernel parameter must be passed to the boot loader.
all-generic-ide=1
To make a permanent change, append the entry to /boot/grub.conf. Here is a sample content:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sda3
# initrd /initrd-version.img
#boot=/dev/sda

This option is not required if using the ASL kernel version 2.6.17-1.2157_FCXasl.3 or greater.
