AX = 7F00h
Return:
AL <> 7Fh if not supported AL = 7Fh if supported AH = status 00h successful ES:DI -> info structure (see #00201) 01h failed
Program: The SOLLEX (Smos videO controLLer EXtensions) SuperVGA functions are an extension to the VESA SuperVGA BIOS Extensions (see AX=4F00h) by Seiko Epson Corporation intended to provided a standardized interface to SuperVGA functionality not addressed by the VESA standard
