; Data structure describing mouse device Flags, IO Base, IRQ number,
;  Mouse type, Mouse port number, mini driver reference, DevNode handle,
;  IRQ handle, interrupt routine, reset routine and disable routine.
; The mini mouse driver receives this data structure, does its detection
;  and sets appropriate flags and then fills in the HW int, reset and
;  disable routine addresses(zero address means NULL routine). The
;  reference data can be used in any way the mini driver wishes.

; The DevNode for a Mouse device looks like follows:
;
; * Hardware section *
;
; [HLM\Enum\root\*PNPXXXX]
; DeviceDesc=MouseType
; Class=MOUSE
; Driver=Pointer to driver (software section) (Mouse\xxxx).
; BootConfig=..... (Base and IO ranges allocated to the mouse).
; MouseDriver= Optional (handles specific hardware and or software).
;
; * Software section *
;
; [HLM\System\CurrentControlSet\Services\Class\Mouse\xxxx]
; DriverDesc=description of driver
; DevLoader=*VMOUSE
; MouseType=type of mouse (Serial,PS2,Inport,Bus etc.)
;
;
; Till Device_Init, VMOUSE returns all New_DevNode calls with
; CR_DEVLOADER_NOT_READY.
;
; After the Device_Init:
;
; When VMOUSE gets a new devnode call for such a node,
; If MouseDriver entry doesn't exist (of the form mousedriver=xyz.vxd) then
;  look at the MouseType and call the appropriate routine to detect the mouse
;  and configure the mouse support.
; else
;  load the VxD. Then call the SYS_DYNAMIC_DEVICE_INIT proc for the VxD
;  with EBX = VM handle and ECX -> Mouse_Instance structure. The VxD
;  returns with the Mouse_Instance struct initialized. If a mouse is found
;  by the xyz.vxd, then it should call VMD_Set_Mouse_Data to let it know 
;  VMOUSE about the mouse. 
;
; If by the start of the Init_Complete process, VMOUSE doesn't detect a mouse,
;  it searches for all mice it can handle and configures the first mouse.
;  Now it remembers the type of the mouse found AND uses this information
;  at the start of the next boot (after it has gone through the above
;  process of handling devnodes) to reduce the boot time.
