Hi Michael,

I tried the patch you supplied but this time no iPXE message is displayed and
the card still doesn't appear as a bootable device in the BIOS.  As soon as I
flash the default Intel pxe ROM back onto the card I see POST message from the
card and it's again available as a boot device.

Any other ideas?  Or should I just give up on the HP machine?
