MS Windows - GET DEVICE API ENTRY POINT

AX = 1684h
BX = virtual device (VxD) ID (see #02642)
ES:DI = 0000h:0000h

Return:
ES:DI -> VxD API entry point, or 0:0 if the VxD does not support an API

Note: Some Windows enhanced-mode virtual devices provide services that applications can access. For example, the Virtual Display Device (VDD) provides an API used in turn by WINOLDAP.

Notes: The high bit of the VxD ID is reserved for future use. Originally, the next 10 bits were the OEM number which was assigned by Microsoft, and the low 5 bits were the device number. Currently, Microsoft assigns VxD IDs individually for each driver; send blank email to vxdid@microsoft.com for more information.. "CallOut"=Y indicates that the VxD uses the INT 2F/AX=1607h/BX=VxDID device callout interface; "PM" and "V86" indicate whether the VxD provides an API entry point in protected mode and Virtual-86 mode (e.g. DOS boxes)
