Yes, I know someone last week asked a similar question (Problem with ASUS P5VD2-X X SATA II) but the only answer I saw on that thread was the equivalent of "I've heard it's bad so I won't do it." Unfortunately, that doesn't help me much. The BIOS does indeed recognise my two SATA hard drives, and I've got the BIOS set to "IDE" (which disables "hardware" RAID but not the SATA but itself). The install routine for Centos, however, does not seem to recognise that the drives are there (or even that the VIA bridge exists via auto search); if I try to manually select it I'm told it found a VIA VT86c100A Rhine-II PCI (via-rhine). Setting to AHCI does not seem to have an effect. I was hoping to use software RAID, and so didn't want to enable RAID on the motherboard. Does anyone have any suggestions as to how to either nudge the installation, or configure the hardware, to find the SATA drives so I can configure RAID? This is a NEW install on new drives, so it's not as if I've got an existing configuration I'm trying to augment. Thanks in advance, -Don
