SCSI Controllers
The system board includes two
∙An
∙A
∙Data transfer rates of 133 MB/sec as PCI bus masters.
∙The connection of a maximum of seven
∙The connection of a mixture of up to fifteen
The system board also includes a narrow SCSI controller integrated as a PCI bus master. You can connect a maximum of seven narrow SCSI devices to this controller.
The SCSI controllers provide active negation outputs, controls for external differential transceivers, and a disk activity output. Active negation outputs reduce the chance of data errors by actively driving both polarities of the SCSI bus and avoiding indeterminate voltage levels and
48 milliampere (mA),
IDE Controller
The PIIX4 multifunction device on the system board acts as a
∙PIO and IDE DMA/bus master operations
∙Mode 4 timings
∙Transfer rates up to 32 MB/sec
∙Buffering for PCI/IDE burst transfers
∙Master/slave IDE mode
