AHA-2740 Series User's Manual The AHA-2740 Series supports only single-ended SCSI devices. Most of the SCSI drives on the market today are of this type. Like all EISA I/O cards, the AHA-2740 Series does not have jumpers to change various EISA configuration options. These options are changed via the EISA Configuration utility provided with every EISA system; however, the AHA-2742/2742T does have a single jumper (J4) that is used to enable or disable the on-board floppy controller.
