I have now set it to active, and upon rebooting, it didn't work (didn't boot). I checked the configuration, and it was still set as active (on PARTITION 1). How do we know which PARTITION to make active? (When I setup the disk I only made one partition with FreeBSD taking up the whole thing) The second disk is also marked as active, and if I unplug the first disk, it will try to boot using the 'second' disk, however it doesn't succeed, as there is not /kernel (THATS OK!) I've tried disconnecting the second drive since it may have been causing a problem, and the same error "Missing Operating System" occurs (I need that first disk to be the boot disk as the other disk is faster) This indicates that maybe something is wrong with the MBR on the first disk, so I did fdisk -b da0 again it didn't work. For some strange reason the CTRL-A doesn't bring up adaptec's SCSI configuration menu, (its in a PII 233). I've never tried to access CRTL-A on this particular machine before. Oh if I boot using the fixit disk, and set the boot drive as 0:da(0,a)/kernel all works ok, just that particular disk won't boot:( Anything else I could try?? > (or whatever is the disk you installed FreeBSD on) to see the layout > of partitions.
