05h program video mode

ES:BP -> video mode table (see #00028)

06h get mode table

AL = video mode

Return: ES:BP -> table suitable for mode AL

(and subfunc BL=05h) (see #00028)

BP = FFFFh on error

SI = 0000h (ATI Mach32)

Note: the ATI Mouse driver (MOUSE.COM/MOUSE.SYS) uses subfunction 06h to get

the mode table for mode 03h, and then looks for a signature string

beginning within 32 bytes of the offset specified by the word at

ES:000Ch
