The ATAPI CD-ROM should appear on the '#H' device along with any ATA drives:

	% ls '#H'
	#H/atapi2disk
	#H/atapi3disk
	#H/hd0disk
	#H/hd0dos
	#H/hd0nvram
	#H/hd0partition
	% 

The naming is weird and i'm not convinced it was a good choice, sorry.
If the device is not on the primary ATA controller then a suitable line in
plan9.ini is required, e.g.

	ata1=irq=15

The 4 possible ATA controllers are at fixed addresses

	Ata0		= 0x1F0,
	Ata1		= 0x170,
	Ata2		= 0x1E8,
	Ata3		= 0x168,

so there's no need to add a 'port=' option. Ata0 is always probed and
doesn't require a plan9.ini line. The 4-disc install should have detected
the CD-ROM and added to plan9.ini if necessary.
