Hi,

if your BIOS doesn't support the disk you're trying to boot from,
and you're trying to use boot.com to boot, you probably have to
stuff a copy of netbsd in the MS-DOS file system and boot from
that instead.  boot.com accepts an MS-DOS file name in addition
to the normal syntax of the boot code.  (If I'm not much
mistaken, boot.com accepts the (default) file name to boot from
as a command line argument.)

I saw a complaint that boot.com could only load smaller kernels.
I'll try to investigate this further and hopefully return with
more information later.
