It looks fine now:
ata0-slave: pio=PIO4 wdma=WDMA2 
udma=UDMA133 cable=80 wire
ata0-master: pio=PIO4 wdma=WDMA2 udma=UDMA100 
cable=80 wire
ata1-master: pio=PIO4 wdma=WDMA2 udma=UDMA66 cable=80 wire
ata3-
master: pio=PIO4 wdma=WDMA2 udma=UDMA133 cable=40 wire
ata4-master: pio=PIO4 
wdma=WDMA2 udma=UDMA133 cable=40 wire


Thanks!
