Int 11  - Bios - Get Equipment List                                        [B]


Return: (E)AX = BIOS equipment list word (see #0158,#2886 at INT 4B"Tandy")

Note:  since older BIOSes do not know of the existence of EAX, the high word
     of EAX should be cleared before this call if any of the high bits
     will be tested
