You may want to try using the Adaptec drivers from Adaptec, and not the
native freebsd drivers.

Edit /boot/loader.conf, and that may be it.

I've found great success with them.

Hi all,

I'm having some problems installing FreeBSD 6.3 on my machine equipped with

Single channel Adaptec? AIC-7901 controller for Ultra320 SCSI
Host RAID 0, 1, 10 support

I have 4 disks which are configured in 2 Raid1,

the problem is when I try to install FreeBSd from the installer cd, it shows
only the separated disks.

I've added also ahd_load="YES" into /boot/loader.conf on the installation
also on the boot prompt
load ahd
load ahd.ko
and then boot

but again with no success .
It were recognized only the 4 disks as separated.

How can I make it recognize the raid ?

Thanks in advance.
