These functions are defined by Seiko Epson as a generic interface for functions not covered by
the Video Electronics Standards Association or IBM's standard video BIOS. This specification is
soon to be outdated, as VESA is now in the process of developing Flat Panel, Power Manage-
ment and Display Data Channel specifications. With version 2.x of the SPC8104 BIOS, the Sollex
