Do you or anyone have experience with boot proms on Apple Ethertalk cards?
This is commonly done on PCs (eg, 3Com to boot from their XNS 3Share server,
as well as Suns (seems to be no standard boot protocol in the IP world)).
Probably the 3Com people who designed the Ethertalk card for Apple have
done it, but the support for it in the MacOS seems to be a hot issue (read,
sensitive until the recall issue is behind them).  Anyone care to speak up?
