And that's all it writes. The test gpxe was build using:
http://rom-o-matic.net/gpxe/gpxe-git/gpxe.git/contrib/rom-o-matic/
(3:37:09 PM) stefanha: Select: .kkpxe, undionly, skip the PCI ID, and
click "Get Image"
If I build a gpxe with the same settings but using serial console with
COMPRESERVE I am
able to see the gpxe boot info even though the bios console
redirection is unchanged
from the original test case.
System is a supermicro motherboard.

Not sure that this is the case for you, but beware of double-redirection
efforts... If your BIOS provides console-over-serial, then there's no
need to compile gPXE with serial output; the BIOS will take care of it.
If you compile gPXE with both "normal" PCBIOS console output as well as
serial output and you have console-over-serial redirection enabled in
your BIOS, then gPXE will output to the console, which the BIOS will
redirect to the serial, but then gPXE will also output to the serial, so
you'll have the output on the serial twice, which typically resembles
garbage.
It might be useful to use a gPXE script and some 'echo' commands to send
some output.
