DOS/32 Advanced DOS Extender - Programmer's Reference 4.01 - VGA function 1Bh - Read Functionality Information
In: | AH = 1Bh EBX = 0000h (implementation type) ES:EDI = pointer to 64 byte buffer
Out: | AL = 1Bh (if function supported by VGA BIOS) EBX = implementation type ES:EDI = pointer to buffer filled with VGA BIOS information
Notes: a) This call can be used to determine whether a VGA BIOS is supported by the Video BIOS in ROM. If function returns AL=1Bh, the machine is VGA compatible. To determine the presence of the VGA BIOS you can also call VGA BIOS functions AX=1A00h and AH=1Ch. Copyright © Supernar Systems, Ltd. 1996-2002 All Rights Reserved.
