Mylex DAC 960

[Dusan Kozic]

Hi,

I installed FreeBSD 4.8 on IBM PC server 520. When I'm booting FreeBSD
on this machine, I see this:

- Disk error 0x1 (lba=0x263e080)
No /boot/loader
>>FreeBSD/i386 BOOT
Default: 0:ad(0,a)/kernel
boot:
WARNING: loader(8) metadata is missing

And dmesg:

I must on each machine startup manually enter the path to my Mylex RAID.
If I disable Adaptec SCSI on this machine, there is same error. So I
don't know how can I fix this...
There is no IDE disk in this machine, so I don't know what mean this:
Default: 0:ad(0,a)/kernel
