5-1 INTRODUCTION TO ULTRA-SCSI
Your new SYD6IBA high-performance Motherboard is equipped with the onboard Adaptec® AIC-7880 Ultra SCSI host adapter for your high bandwidth applications, providing data transfer rates of up to 40 Mbytes per second. The Ultra-wide SCSI is an input/output bus interface that provides a powerful multitasking interface between your computer’ s PCI bus and your SCSI devices.
With SCSI, you can connect a variety of devices on your computer (Hard/Floppy Disk Drives, CD-ROM Drives, Scanners, Tape Drives, Removable Media Drives, etc.) in a daisy-chain topology to a common host adapter. Daisy-chaining SCSI devices allows them to communicate with each other by sending commands and data via the SCSI bus.
The AIC-7880 Ultra SCSI provides maximum data transfer rates of 20 Mbytes/sec in the narrow 8-bit mode (Fast SCSI) and 40 Mbytes/sec in the wide 16-bit mode (Ultra-Wide SCSI).
