Leave the BIOS in there, and use uIP stack.
It works on a C64, which is 1MHz, so 4.77 should be a breeze.
I don't know the URL offhand, but Cameron probably does.

Subject: Re: CP/M TCP/IP (was Re: CP/M coding question)
I'm starting to have some second thoughts about
how I'm going to do this.
I'm considering an external 'black box' that will connect to a PPP server
on one end and have a RS-232 connection on the other that will provide
Not realy the same thing, but related...
I've considered pulling the BIOS ROMs from an old XT or AT system
(preferably IBM as I have the schematics...) and replacing them with some
kind of TCP/IP stack. Stick an ISA ethernet card in one of the slots (or
a serial card and use SLIP or PPP) and fill up the other slots with
whatever I/O cards would be appropriate to connect to the CP/M box or
whatever. Without the IBM BIOS getting in the way, the 8088 should have
enough power for this, and without the BIOS there'd be no reason to have
a video card or keyboard (or disk drives).
Has anyone ever tried this, or anything like it? I really don't feel like
writing all the code from scratch...
