You must terminate the SCSI bus properly. The SCSI bus on each SCSI channel is an electrical transmission line and it must be terminated properly at both ends to minimize reflections and losses. You complete the SCSI bus by setting termination at both ends40 MegaRUM PCI Motherboard User’s Guide SCSI Termination PossibilitiesStep 11 Connect SCSI I/O, Continued Step 12 Install Drivers Review the following points before powering up 2 WINBIOS Setup Using a Mouse with WINBIOS Setup Using the Keyboard with WINBIOS SetupMain Windows The WINBIOS Setup main windows are Standard Setup Section 1 SetupSelect Type.
