BX = page number (0000h-003Fh)
Return: AX = status (0000h,0001h,0007h,0008h) (see below)
Program: FGDRIVER is the external video driver for the shareware
Fastgraph/Light by Ted Gruber Software
Notes: For FGDRIVER v1.10, this function was "FG_GETMODE" (see AX=003Fh);
"FG_ALLOCATE" was AX=0042h
The amount of memory required by the virtual video page depends on the
current video mode
The installation check consists of testing for the signature "FG" ten
bytes beyond the start of the interrupt handler
