RFC on solution to Rejean's situation

[Rejean Proulx]

Thanks,  I've got garbage lying around that I can probably get 128M for.  It
might be overkill, but here it is.  One of the boxes is a 333MHZ so it
should be plenty.  Does it need a hard drive or can I just boot it off a
floppy for this sort of thing.  None of my garbage has hard drives anymore,
but I'm sure I could come up with a hard drive.
