I wasn't as lucky as Doug with my ASUS P4C800-E Deluxe board, both with
the ICH5R and Promise RAID controller.

1) With the Promise controller, after simulating a disk problem
(shutdown - disk disconnection - reboot - shutdown - disk reconnection -
reboot), I wasn't able to rebuild the array at all, either with
"atacontrol rebuild ar0" or from the bios. I suspect a spare disk is
necessary for a complete rebuild.

2) With the ICH5R controller, installation went fine too. If I
disconnect a disk, the system still boots, but when I plug the disk back
(computer shut down), no boot is possible anymore. At boot, a kernel
panic says: "softdep_setup_inomapdep". No array rebuild is possible from
the bios, so I'm stuck.

I use freebsd 6.1 RELEASE, with the latest BIOS for the motherboard, and
2 SATA 1.0 Western Digital 160GB disks. I'm trying to configure RAID 1.

I'm surprised I have so many problems. Am I doing anything wrong? With
INTEL hardware controllers for SCSI disks, I never had any problems
until now. Does anyone successfully use another ASUS board, and is able
to rebuild the array, without rebooting?

Thanks for your time,
