Paul Moody posted a good miniHOWTO to this list last year. I found the
following URL:
http://lwn.net/lwn/980430/miniHOWTO.html
As I recall, it doesn't go about using a ROM image, but a flash disk
(subtly different, I would say). The ideas should be the same.
There is also a a BootROM information at
http://www.charm.net/~john/bootrom.html
It's commercial, but pretty cheap. The page is also from 1995, so who
knows if its still viable.

As far as configuring a minimal system, check out tomsrtbt
(http://www.toms.net/rb) and muLinux
(http://www4.pisoft.it/~andreoli/mulinux.html). Both of these are single
floppy disk Linux. tomsrtbt is an excellent emergency boot disk and can
also be used for diskless machines (by leaving the floppy disk in the
drive) for mounting via NFS or SMB (I think). muLinux is a great way to
demo Linux or as a low-maintence network station. It has web browsers,
has sends and receives email, has small web server, can do sound, dial out
and use ppp, and with a second disk can do X Windows. Embedding one or
the other of these in ROM would be cool.
