If it's the same type of VAIO outboard CD drive that my old laptop has,
then no.  The obstacle is that its ATA interface must be addressed on a
non-standard I/O base address that doesn't usually get autoprobed
correctly.  So, you pass 


to the kernel, at boot time, to inform it of the correct I/O port.
