; Inputs: [dib_ptr] = Last DIB built (LONG)
; Acc = Unspecified
; Carry = Unspecified
; Y register = Unspecified
; X register = Unspecified
; P register = 0=M=X=e

; Outputs: Acc = DRVR_BUSY
; Carry = 1
; unless we have no more dibs then
; Acc = 0
; Carry = 0

; Y register = Unspecified
; X register = Unspecified
; P register = 0=M=X=e
