; Prints Hard Disk configuration for drive handled by our BIOS.
; Cursor is set to configuration header string position.

; BootMenuPrintCfg_ForOurDrive
;	Parameters:
;		DS:DI:		Pointer to DPT
;	Returns:
;		Nothing
;	Corrupts registers:
;		AX, BX, CX, DX

; PushAddressingMode
;	Parameters:
;		DS:DI:	Ptr to DPT
;		CS:BX:	Ptr to IDEVARS
;	Returns:

	;;
	;; This multiply both shifts the addressing mode bits down to low order bits, and
	;; at the same time multiplies by the size of the string displacement.  The result is in AH,
	;; with AL clear, and so we exchange AL and AH after the multiply for the final result.
