Bios; Usb/Ide Controller; Network Controller - NEC Express5800 320La User Manual

BIOS

The BIOS and Setup Utility are located in the Flash EPROM on the CPU board and
include support for system setup and legacy device configuration. A number of security,
reliability, and management features also have been incorporated to meet vital server
needs.

USB/IDE Controller

The ServerWorks ROSB chip supports the USB and IDE controllers. The I/O panel
board provides the connector interface for two USB ports that support the keyboard and
mouse.
The system includes a single channel enhanced IDE 32 bit interface. The IDE controller
provides support for the internally mounted CD-ROM and super floppy disk drive.
The device controls:
PIO and DMA transfer modes
!
Mode 4 timings
!
Transfer rates up to 33 MB/s
!
Buffering for PCI/IDE burst transfers.
!

Network Controller

Each PCI CRU includes a 10BASE-T/100BASE-TX network controller based on the
Intel 82559 Fast Ethernet Network Interface ASIC. As a PCI bus master, the controller
can burst data at up to 132 MB/sec. The controller contains two receive and transmit
FIFO buffers that prevent data overruns or underruns while waiting for access to the
PCI bus. The controller has the following:
32-bit PCI bus master interface (direct drive of bus), compatible with PCI Bus
!
Specification, Revision 2.1
Chained memory structure with improved dynamic transmit chaining for
!
enhanced performance
Programmable transmit threshold for improved bus utilization
!
Early receive interrupt for concurrent processing of receive data
!
On-chip counters for network management
!
Autodetect and autoswitching for 10 or 100 Mbps network speeds
!
Support for both 10 Mbps and 100 Mbps networks, capable of full or half
!
duplex, with back-to-back transmit at 100 Mbps
Support for Wake On LAN.
