This is the only alpha I have.  I can't build a kernel until I can boot
it.  I've tried booting the install disks, exiting the installer, and
mounting wd0, but I still can't build the kernel sources using the
limited single user environment the install disks present me with.
There used to be a GENERIC.fs floppy built with the release that could
be used for this purpose, however it's not available any longer,
presumably due to overflowing the size limitations of a floppy.  It
seems to me one shouldn't need a kernel on the actual floppy if the
second stage bootloader was smart enough to recognize wd0 as a boot
