It appears that I'm not the only one struggling with the RAID1 using Intel's ICH6R. (My mobo is a Tyan S5150 with two identical 80GB WD SATA drives.) Using either 5.4-RELEASE or 6.0-CURRENT-SNAP004 the OS seems to load from the release CD but fails to boot from the RAID array. (5.4 drops into boot loader and 6.0 can't find the OS.) Both operating systems boot fine without a RAID1 array and both disks come up. I even tried building the mirror then disabling one drive using the firmware setup. The firmware says then to have the OS rebuild the mirror. OK,... The OS then boots fine to ad4 and can see ad6. I can dd if=/dev/ad4 of=/dev/ad6 successfully, but I cannot get atacontrol to rebuild the mirror. Maybe this approach will work, and I'm doing something wrong... Now man ata(4) indicates that only up to ICH5 is supported in 5.4 while up to ICH6 is supported in 6.0, but the hardware archives indicate that sos's MK3 patches made it into 5.4-RELEASE, and 6.0 "fully" supports the ICH6R. However, I'm actually not sure the precise story here. Has anyone out there actually booted FreeBSD using mirrored SATA drives with an ICH6R? If so, how did you do it and what version did you use? I could really use some help! Thanks, -gayn
