Do you think it is possible to also install SCO-Unix in a third boot |> partition and swith all OS e.g. by a boot-switch program like os-bs ? 1) Setup for the real geometry of the disk. 2) Modify asboot to look at where you will be putting your 386BSD partition (it currently believes it should be the first one). 3) Make a new dist.fs disk (from an old dist.fs disk): strip 386bsd # My new kernel mount /dev/fd0a /mnt rm /mnt/386bsd cp 386bsd /mnt sync umount /mnt 4) Install DOS on the front of the disk. 5) Install 386BSD with your new dist.fs. WARNING: This is not for the faint of heart, as it involves installing 386BSD twice, the first time on the whole disk simply to build a kernel for the second installation. Note: Modification of asboot to look at the driver partition table is to be forthcoming, but don't bug me for it; I'll post a patch here and a dist.fs to agate when I'm done.
