is this a sata or pata disk? if this is a sata disk, i believe this chipset is already supported in ahci mode. we have machines around here with the same south bridge. to enable ahci mode in bios, generally one needs to change the sata mode to enhanced and, for this particular chipset, i believe it's necessary to enable ahci mode. for the esb chipsets enabling ahci mode is not necessary. when you enable ahci, you should have a second device show up that starts 0x27cx. - erik
