AX = 7A20h BX = 0000h
Return:
AX = 0000h on success (installed) ES:BX -> far call address for DOS Requester (see #02859)
Notes: The DOS Requester replaces the NetWare Shell (ANETx, NETx) on NetWare LAN's as of the release of Advanced NetWare 4.0 (1993). It is backward compatible with NetWare 2.1x through 3.11 servers as well. Note that there was a NetWare 4.0 in the early 1980's, which can cause confusion.. This call is used as the installation check by VLM.EXE, which is the loader for all the modules of the DOS Requester. .VLMs are standard old .EXE format executables whose normal entry point merely terminates to prevent loading from the command line (Novell's VLMs all return errorlevel 6). The real entry point is found by looking at the VLM header at the beginning of the load image (see #02862)
