On i386 (and maybe amd64?), NetBSD can be started from DOS with dosboot.com,
though that seems to no longer work beginning with NetBSD 5.0.2.
I still can't boot NetBSD 5.1 directly from wd0a ("Error Not a bootxx image")
and have been unable to fix that even with installboot. But I made a small
hard-disk or giant-floppy image with ffs file system, disklabeled and newfs'ed,
ran installboot and copied the desired kernels as well as the secondary boot
loader (/boot). I can boot that from FreeDOS with grub4dos, then interrupt the
boot process to input "boot netbsd -a", or other kernel, and choose wd0a for
the root. Question is whether I could also choose something other than a if I
had another NetBSD installation there.
Another possibility would be to put root partition on a USB stick and "mount
/dev/wd0f /usr" or something like that: only an idea on my part, I haven't
tried and don't plan to try on present old computer, dating to just before USB
2.0 became widely available on motherboards: not enough disk space, only 256 MB
RAM, and USB on motherboard is 1.1.
I don't think virtualization is a good bet on my present computer, believe
virtualization is much slower than running normally.
