If have any disks connected to the 810, then the system loads kernel off the first disk on the 810 change and everything else off of the first disk on the 875 chain. I suspect that the MBR is off of the 875, but I'm not positive. How does the BIOS choose which MBR to use? How does the MBR choose which kernel to use? How does the kernel choose which ncr is ncr0 and which is ncr1? In my case, it seems to be: BMR: 810 kernel: 810 ncr0: 875 Thanks, -Dave
