I have my IBM 5155 Portable PC booting now, with an EtherLink II nic that has room for an 8KB ROM in it.

Some candidates for what to put in the ROM:

ftp://ftp.dunfield.com/embedpc.zip
Files for "embedded" PC's, includes a boot disk maker, a DOS compatible file system, windowing functions and more

MON88
http://www.ht-lab.com/freeutils/mon88/mon88.htm
Debug Monitor and Tiny Bios for the 8088/8086 Processor (would need to be trimmed down to 8KB)

This is a plugin for the OshonSoft Z80 Simulator IDE

It emulates a VT100 terminal, which is connected to the Z80 via a serial IO controller that uses port 40h for the status register, and port 41h for the data register.

I put this together while working on a little Z80 monitor which (once there's enough room in the house to let me unpack things) I plan to burn into some EPROMs and use to revive some old z80 based luggable PCs (namely, an Osborne 1 and a  Bondwell 14)

Here's a screenshot of the rom monitor running in the simulator:
