VGA BIOS Configuration
The system BIOS on the Super Voyager LPX motherboard
implements INT 15h function AX=448Eh. When issued, the INT
15h AX=448Eh function signals that the video BIOS is ready to
accept INT 10h option calls. When this interrupt is received, the
system BIOS performs any option selection required via INT 10h
Function 12h, as described on page 109. The video BIOS invokes
this INT 15h call before the initial mode set and displaying the sign
on message.
Before any mode set the video BIOS issues an INT 15h function
AX=F965h call. This is a signal to perform any clean up that must
be done before the mode is set, such as setting a montype for a non-
standard monitor.
