INT 2F - INTERLNK - INSTALLATION CHECK AX = 5600h DX = magic value FFFFh BL = instance number (00h = any, 01h = first loaded, etc.) (BH = 00h and CX = 0000h, see note) Return: AL = FFh if installed BL = instance number CX = version number (CL = major, CH = minor) DX = resident CS of driver, DX:0000h -> header (see #02845) Notes: INTERLNK was derived from Sewell Development Corporation's FASTLYNX. Some Microsoft software explicitly clears the BH and CX registers before calling this function. BUG: reportedly, the MS-DOS INTERSRV program (though not INTERLNK) causes serious FAT corruption and data loss when run under Novell DOS 7. INTERSRV apparently checks for DR-DOS by testing the "OS" environment variable for the value "DRDOS", which is no longer correct for PalmDOS, Novell DOS, or OpenDOS. A workaround may be to explicitly set the OS variable to "DRDOS". SeeAlso: AX=5601h,AX=5602h,INT 60/AX=0000h
