[gPXE-devel] [PATCH]: Making gPXE silent when CONSOLE_DIRECT_VGA is unset

[Erwan Velu]

Hey folks,

I'm running gPXE is an industrial environment where all the bios
message must be hidden. We do have a tweak bios that do this job.

Since I added gPXE instead of my original ROM, I disabled the VGA
screen by using CONSOLE_DIRECT_VGA and enabled the serial line for
debugging purposes.

That works nicely except a last message is remaning "gpxe (pciid) -
starting exec".

While looking at the code I saw this message is printed
uncondtionnaly. I wrote a stupid patch that ifdef that section.

If this patch make sense for you too, can it be pulled upstream ?

Sincerly,
Erwan Velu

The patch looks like :
