etherboot card for TLAN

I'm setting up a test LTSP server, and I have a Compaq Deskpro
4000 to use as a client. The Deskpro has an embedded Netelligent
NIC, the chip on which I'm led to believe is a Texas Instruments
TLAN. I went to www.rom-o-matic.net and tried to get an
etherboot image for this NIC, but it isn't listed. Has anyone
worked on this problem?

Thanks, Scott
