gPXE and Dell PE1950 - BCM5708

I'm having trouble getting gPXE to flash into a BCM5708 card installed in
a Dell Poweredge 1950.

The example: http://etherboot.org/wiki/romburning/tg3 didn't work becasue
the b57udiag application didn't see any broadcom cards.

I found that uxdiag worked in detecting the cards but I still can't get
the gPXE image to flash to the card.

Using:

uxdiag -c 1 -fmba c:/14E4164C.ROM  -t abcd

I get:

uxdiag -- Broadcom NetXtreme II diagnostics version 5.0.5

What can I do?
