SCSI Jumper

The SCSI interface's autoboot option should be turned off if there are no bootable devices or any devices at all attached to the SCSI bus. This prevents a 30 second delay while the system attempts to detect bootable SCSI devices. It is possible to upgrade this card to an 060 with an appropriate voltage regulator.
