Int 2D

AMIS v3.6 - GET DEVICE-DRIVER INFORMATION

AL = 06h
AH = multiplex number for program

Return:
AL = number of device driver headers supplied by prog.
AH = device-driver flags (see #02576)
DX:BX -> first device driver header (see #01646)

Program: AMIS is the Alternate Multiplex Interrupt Specification promulgated by Ralf Brown

Notes: If AL=00h, AH,BX,DX are meaningless and may be destroyed. This function is not valid unless a program is installed on the specified multiplex number; use INT 2D/AL=00h to check. Programs which provide device drivers are required to support this function to be considered fully compliant with v3.6+ of the specification

Bitfields for AMIS device-driver information flags:

Bit(s)  Description     (Table 02576)
0      program loaded from CONFIG.SYS, and thus can not be removed from memory.
(leave clear if unable to determine)
1      device driver headers have not been linked into DOS device chain
2      reentrant device driver(s)
