Using the latest version of syslinux/pxelinux..

When cold pxe booting a HP DL585 G2 (Broadcom NIC), if the pxemenu item is 
LOCALBOOT 0 and is selected, then a red screen with the following error 
occurs:

      Illegal OpCode 

EAX=000E09AC  EBX=00000000  ECX=00000000  EDX=00000000
EBP=00004408  ESI=0000F000  EDI=000045E9
DS=F000       ES=0000       FS=0000       GS=0003
CS:EIP=1000:00000240        SS:ESP=0030:0000FBE6
EFLAGS=00000047

This is all pre-operating system.


Oddly enough, if I bypass the pxeboot process, the machine boots fine 
locally, and on subsequent reboots, pxelinux properly localboots the 
machine.  This only occurs on a "localboot 0" situatation when the machine 
is booted from a powered off state.

It only happens on this particular hardware as well (it's firmware is 
fully up to date).  I will take this up with HP, but I just wanted to make 
sure there was nothing obvious. 

Thanks,
