Must VGA BIOS go first ?

[Kees]

Hi there!

I am wondering why the VGA BIOS is shown first and then the POST of
the BIOS starts.
There could be some time saved when it could be skipped, but HOW??
Anyone who can help me on this one??

Thanks very much !

Yes the VGA Bios has to be initialized first, it's a so called extension
Bios.
Before real testing starts the System has to know about it exists and
the initialization loads (replaces) INT 10H vectors.
That in turn is needed to show the Bios POST screen.

It's probably coded in the MB BIOS. But doesn't the video bios have to
be initialized first, so that the rest of the POST will be shown on the
screen?
