Bios Mods -The Best BIOS Update and Modification Source

hi every1
i have this MB gigabyte 8ik1100 rev 1(one)

surprise is that it has 8knxp rev2 bios fj version. i even did upgrade to fk.
and it works.

i thought bios upgrade can enable "lan boot rom" to boot by PXE .
but failed.

this MB cant boot over PXE.

any help please?

version EZ.
unexcpectable for me. manuals do not says about that.

bios was disassembled . some roms were released and ipxe rom added
now this MB works with PXE.
tools:
cbrom, ipxe.org
