VxDcall V86MMGR_Get_Xlat_Buff_State

Gets information about the current mapping buffer status. Uses EAX, ECX, EDX, Flags.

Returns with these values in these registers:

EAX	The V86 segment of the translation buffer; the high word is zero.
ECX	The number of bytes of the buffer not in use.
EDX	The total size of the buffer in bytes; the maximum size is 10000h.

VMHandle: Handle of the VM.

Always call this service to find the segment of the translation buffer. Because the buffer can move at any time, a virtual device should never make any assumptions about the size or location of the buffer.
