DESCRIPTION
This library provides initialization routines to configure VGA in 3+
alphanumeric mode.
The functions addressed here include:
\ms
\m -
Initialization of the VGA specific register set.
\me
USER INTERFACE
\cs
STATUS vgaInit
(
VOID
)
\ce
This routine will initialize the VGA specific register set to bring a VGA
card in VGA 3+ mode and loads the font in plane 2.
