Dunno where else > it could be put 8) On one line of the boot prompt it say hd(1,a), and another line says wd(0,a). There is a potential confliciting message there. Someone who knows that FreeBSD refers to disks as either wd or sd, hd(1,a) could easily be interpreted as meaning you should type sd(1,a) or wd(1,a) to boot from the second disk, be it SCSI or ide. Personally, I've always been puzzled by the first line in the boot prompt. Again, I think it would be really nifty to move some of this boot configuration stuff into userconfig where there is a bit more room to provide a usable interface. > There's a #define for /sys/i386/boot/biosboot/boot.c - BOOT_HD that > builds a bootblock that boots from the _second_ bios disk, but passes > in a minor number of 0 to the kernel.

Looks like my course in 80x86 assembly may finally be of some use... -john == jfieber@indiana.edu =========================================== == http://fieber-john.campusview.indiana.edu/~jfieber ============
