btx/pxeboot problem

[Danny Braniss]

latest pxeboot (7.1):
	mother-board	NIC/LOM	CPU
	-------------   ------- ---
	Intel SWV25	 em	xeon	works fine
	SUN X2200	 bge	amd	works fine
	DELL PE 2950 	 bce	xeon	failes 95% of the times
					hangs or goes into btx dump regs. mode :-)
	Intel SE7320VP21 msk	xeon	failes 50% of the times - hangs

pxeboot with btx.S 1.45 2008/02/27 23:35:39, works fine.

so it seems that changes since 1.45 have fixed it for some, but it
brakes for others :-). I can help testing, but btx is way out of
my league.
