[Linux] no video bios message before POST

[Aaron Wolfe]

Have you considered that maybe the new monitor just takes longer to display=
 a picture than the old one?  I have seen monitors that took so long to kic=
k on that you couldn't even catch the normal bios screen.  Monitors that at=
tempt to be green by turning off whenever there is no video signal seem to =
vary greatly in how quickly they decide to turn off and how reluctant they =
are to turn on again.

Is the only "problem" that you don't see the initial video card message?  I=
f the system works fine otherwise, I wouldn't spend any time worrying about=
 it.
