I'm reasonably certain that it's not possible using the serial link:
The main serial link is used as the console.  According to my reading
of the kernel config file, the second link is "reserved for low-level
IO" (though I haven't tried using it).

It's just painful over Ethernet: The Multia SRM is broken in ways that
are incompatible with netboot: The SRM is old enough to require the
MAC address hard-coded into netboot (reasonably simple given a binary
editor and a 64-bit hex calculator), but does not meet netboot's
associated definition of `broken_firmware'.  This basically means that
you either need a _good_ binary editor (capable of patching constants
buried in the code), or you need to re-compile netboot.  The
3.2-RELEASE (and earlier) netboots also abuse DHCP (this is fixed back
to BOOTP in the later versions).

The easiest way is probably to DD the 2.88MB boot image onto a SCSI
disk.  This can be the same disk you're installing to (though you'll
get a warning about partition size mismatches, which can be safely
ignored).
