According to the Tech Reference, BIOS routines are available to change
the active display page for alphanumeric mode (INT 10H, AH=5). Peter
NOrton's new book ("Programmer's Guide to the IBM PC") also describes
this service routine. These routines let one switch the page actually
being displayed, but I can find no way to set which page is being
written to by the BIOS routines. His book also hints at sub-codes
for the INT 10H ah=5, such as "set CPU display page register" (p.230).
Anybody know how to use this stuff?
I want to be able to prepare new
screens in the background while the user is reading the currently
displayed screen.
Any help is apreciated. Please reply via mail.
