Understand that there is NO GUARANTEE that this 
procedure will work with future releases of the drivers. It is 
known to work through version 3.0 ETH and ETH505 drivers

Procedure:
.lt

        1 - get the drivers entry point as follows:

            mov ax,3d02h
            mov dx,offset filename
            int 21h

            mov bx,ax
            mov ah,40h
            mov dx,offset data
            mov cx,1
            int 21h

        filename:   db  "MINDSETH",0
        data:       db  01,00
        offset:     dw  0
        segment:    dw  0
.el

After executing this program, the segment and offset of the 
MINDSETH driver entry point will be in "segment" and "offset".
Now execute a string search routine from the following addresses.

    segment:0 to segment:offset

where segment and offset are values returned by the previously 
described program. Search for the string "LASSWELL" (all caps). 
This string only occurs in the ETH505 driver.
