Novell DOS 7 - EMM386.EXE - MULTITASKING API - DPMI SERVICES

AX = 2780h
CL = 06h
CH = function
00h "F_InitDPMI" used for internal initialization
01h "F_DescAllocLDT" allocate LDT descriptor
02h "F_DescFreeLDT" free LDT descriptor
03h "F_DescGetLDT" get details on LDT descriptor
04h "F_DescSetLDT" set up LDT descriptor
05h "F_DescAllocInt21" allocate descriptor for PM INT 21
06h "F_WhereIsDPMI" get address of DPMI global data

Return:
???

Notes: Called by DPMS.EXE and EMM386.EXE. The handler for this function may be set by one of the subfunctions of AX=2780h/CL=01h; the default handler returns AX=BX=FFFFh and CX=0001h (see #02739). This API is only available if AX=12FFh/BX=0EDCh returns successfully; because the request is handled on the initial trap to the memory manager caused by INT instructions, this API must be invoked with an actual INT 2F instruction instead of some simulation such as a far call to the address in the interrupt vector table
