Hi !
I have patched 2.4.34 with the following patch to allow the use of SATA
drive on an ICH8 motherboard :

This works fine for the disk but this does not work for the CDROM. Here

I suppose the problem is "dev 1 not supported". From source, I see that
it is because, no DMA support was available.
With a 2.6.18, I get :
Jun 11 07:44:27 debian kernel: ata1.00: ATA-7, max UDMA/133, 156250000 sectors: LBA48 NCQ (depth 0/32)

Jun 11 07:44:27 debian kernel: ata_piix 0000:00:1f.5: MAP [ P0 -- P1 -- ]
Of course, I have compiled CDROM support :
CONFIG_BLK_DEV_SR=y
# CONFIG_BLK_DEV_SR_VENDOR is not set
If I try AHCI driver instead (and add PCI ID into ahci.c), I get an oops
(libata-compat.h, line 141).
Now, back with ata_piix, it seems that because of PIO error,
all capabilities are set to 0. In 2.6, PIO error seems to be handled
differently.
Any hint on how to fix this ?
Thanks.
