And that's all it writes. The test gpxe was build using:<br>
<br>
<a href="http://rom-o-matic.net/gpxe/gpxe-git/gpxe.git/contrib/rom-o-matic/" moz-do-not-send="true">http://rom-o-matic.net/gpxe/gpxe-git/gpxe.git/contrib/rom-o-matic/</a><br>
<br>
(3:37:09 PM) stefanha: Select: .kkpxe, undionly, skip the PCI ID, and
click "Get Image"<br>
<br>
If I build a gpxe with the same settings but using serial console with
COMPRESERVE I am<br>
able to see the gpxe boot info even though the bios console redirection
is unchanged<br>
from the original test case.<br>
<br>
System is a supermicro motherboard.<br>

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.<br>
<br>
It might be useful to use a gPXE script and some 'echo' commands to
send some output.<br>
