i'd bet that you need to have your cdrw on one ide cable and your
system disk on a different cable .. 

and you would need to set your cdrw to udma2 ( ata-33 )
	hdparm -d 1 -X 66 -m 16 -c 1 /dev/hdc

also be sure that your kernel supports the ide chipsset on the mb

and you might want to try using an ata-66 ( 80-conductor ) cable to see
if it helps any

-- note fastest supported dma speed
	-- all other drives on this ide cable should be udma2 ( ata-33 )
