thank's for your reply. About the pg, i did it according to result of search i made on google. however this confus me, because in the doc, it is said that ipg is related to parallel port. I haven't anything on the parallel port. All my devices are on the true scsi chain and are true scsi devices. So what about pg here? Regard's Vincent
