Don't know for sure, but I think you could access disk number 5, but only after the kernel is up and running (and maybe only then with a custom kernel -- see if the LINT file has any hints). With Linux I've accessed disks that were disabled in the BIOS, and I'd be very suprised if FreeBSD were any different in regards to handling disks completely without regard of the BIOS (after booting). I suspect that the limit would be in IRQs for the disk controllers. IRQ 14 & 15 are usually used for the two on-MB controllers, but you can probably find several free ones. I'd be nice to have something like Linux's /proc/interrupts to examine, but I think you'll have to pore through your bootup messages to determine what's being used.
