Thank you. Of course I can use the BIOS to create the mirrored set. But 
after that, can I install FreeBSD with the standard installer?  I'm not 
sure if 'ataraid' is included in GENERIC. Will the installer notice the 
RAID-1 array as a new physical drive? Unfortunately, I do not have the 
hardware yet, so I cannot try this. A real SCSI RAID controller would be 
too expensive for me. If I cannot install the whole system on the 
mirrored set, then probably it is better to use gvinum, because it 
allows me to buy a cheaper motherboard and use different hard drives. 
However, gvinum also has disadvantages (cannot mirror the root fs, or it 
is too difficult and I'm not familiar with vinum...)

Thanks,
