Yes - but kiss off any of the "popular" distributions, like Fedora,
Mandrake, or SuSE. Slackware or Debian are likely alternatives,
and sunsite has a large number of other distributions that might be
compatible. Try http://ibiblio.org/pub/Linux/distributions/

My firewall is running on a 386SX-16 with 8 Megs of RAM and a 213 Meg
hard drive. Are you _sure_ that the current drives are that small?
My first genuine IBM PC-AT came with a 30 Meg drive in 1985, and I don't
even think anyone was making 20 Meg drives when the 386SX came out in
1988. If that really is a 20 Meg drive, you probably also need a new
disk controller, because that's almost certainly a ST506 MFM dog, and
that won't work with any modern disk (or even a lot of obsolete ones
either).

With a 20 Meg drive - not likely (though there are distributions that
will fit on one or two floppies - they just don't do much). Trying to
run anything in 4 Megs of RAM is also going to be very iffy. You're
talking about a server, so that means you don't need a GUI - that will
reduce the requirements by a large extent, but you may need to be using
an older kernel because of bloat (2.0.x or even 2.2.x kernels are a lot
smaller than 2.4.x or 2.6.x. From kernel.org:

See above.
