SCSI Controller
A QLogic 12160 Ultra 160 SCSI chip provides two
Each channel is capable of operations using either 8- or
The QLA12160 has its own set of PCI configuration registers and SCSI I/O registers. As a
PCI 2.1 bus master, the controller supports burst data transfers on PCI up to the maximum rate of 132 MB/sec using
In the
No logic, termination, or resistor loads are required to connect devices to the SCSI controller other than termination in the device at the end of the cable. The SCSI bus is terminated on the
I/O carrier with active terminators.
IDE Controller
IDE is a
∙PIO and IDE DMA/bus master operations
∙Mode 4 timings
∙Transfer rates up to 22 MB/sec (33 MB/sec using ultra DMA transfers)
∙Buffering for PCI/IDE burst transfers
∙Master/slave IDE mode
Keyboard and Mouse
The PS/2 compatible keyboard and mouse connectors are mounted in a
The user can plug in the keyboard and mouse to either connector before powering up the system. BIOS detects these and configures the keyboard controller accordingly.
The keyboard controller is functionally compatible with the 8042A microcontroller. The system can be locked automatically if no keyboard or mouse activity occurs for a predefined length of time, if specified through the SSU (see security options in “ Security
