INT 7F - Non-dedicated NetWare 2.x File Server - ENTER CONSOLE MODE InstallCheck: test for the signature "Lynn" in the four bytes preceding the interrupt handler; if present, the current program is running as a DOS task on a non-dedicated NetWare 2.x file server. Note: Before placing the server into "console" mode, it is recommended that NetWare broadcast messages be disabled with INT 21/AH=DEh/DL=00h.

INT 7F - Alloy 386/MultiWare (MW386), Novell-Type Network Executive (NTNX) Notes: the words at C800h:0000h and C800h:0002h will both be 584Eh if the MW386 multitasking system is present (i.e. signature "NXNX") NTNX allows its API to be placed on a different interrupt than 7Fh at load time. To determine the actual vector used, open the device "SPOOLER" with INT 21/AX=3D02h, place it in RAW mode with INT 21/AX=4400h and INT 21/AX=4401h, then read one byte which will be the actual interrupt number being used; the other interrupts may be found with INT 7F/AH=09h/CL=03hTop
INT 7F - Alloy NetWare Support Kit (ANSK) v2.2+ - INSTALLATION CHECK Note: a program may determine that it is running on an ANSK Slave by checking the five bytes at F000h:0000h for the ASCIZ signature "ANSK"; this address is RAM, and should not be written. However, the above check will not work on Slaves with <1MB RAM or those using the SLIM.SYS device driverTop
