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
