; OPTION TYPE
; -----------
; This identifies the Option type we are dealing with.  The different
; possible types are:
;
; COMPUTER, DISPLAY, MOUSE, KEYBOARD, LAYOUT, SCSI, PRINTER, ...
;
;  Types specific to networking:
;
; NetAdapter,        a netcard / adapter combination or just a netcard
; NetDriver,         just a netcard driver
; NetTransport,      a complete NDIS-compliant TDI transport stack
; NetService,        an NT networking service
; NetWork,           a complete network ensemble.
; NetProvider        a complete network which supports NT MPR protocol
;-----------------------------------------------------------------------

    OptionType = NetService

;-----------------------------------------------------------------------
; OPTION LIST
; -----------
; This section lists the OEM Option key names.  These keys are locale
; independent and used to represent the option in a locale independent
; manner.
