Could it be a "spurious interrupt" generated by the 8259 interrupt controller (PIC)? If an interrupt input to the PIC is not of sufficient duration, it specifies level 7 in response to an interrupt acknowledge from the processor. Since I don't know how the PIC is programmed under SYS V/AT, this is just a guess. richard hargrove ...!{ihnp4 | codas | cbosgd}!killer!richardh --------------------------------------------
