•
Intel 82562ET 10/100-Mb/s PHY
•
Serial ROM for storing the Ethernet address and the interface configuration
and control data
•
Integrated RJ-45/Magnetics module connector on the SBC's I/O bracket for
direct connection to the network. The connector requires a category 5
(CAT5) unshielded twisted-pair (UTP) 2-pair cable for a 100-Mb/s network
connection or a category3 (CAT3) or higher UTP 2-pair cable for a 10-Mb/s
network connection.
•
Link status and activity LEDs on the I/O bracket for status indication (See
Ethernet LEDs and Connectors later in this chapter.)
Software drivers are supplied for most popular operating systems.

NTERFACE
The 845GV chipset utilizes a dedicated hub interface connection between the 845GV
graphics and memory controller hub (GMCH) and the I/O controller hub (ICH4). The
purpose of the 845GV hub interface is to provide efficient, high-speed communication
between chipset components in order to support high-speed I/O applications. It is a
parity-protected, 266MB/s point-to-point hub interface and uses an 8-bit 66MHz base
clock running at 4x.

Dual high performance PCI Bus Master EIDE interfaces are capable of supporting two
IDE disk drives each in a master/slave configuration. The interfaces support Ultra
ATA/100 with synchronous ATA mode transfers up to 100MB per second. Ultra
ATA/100 cables must be used with Ultra ATA/100 drives.

The SBC supports two floppy disk drives. Drives can be 360K to 2.88MB, in any
combination.

NTERFACE
Two high-speed FIFO (16C550) serial ports with independently programmable baud
rates are supported. The IRQ for each serial port has BIOS selectable addressing.

ARALLEL
I
NTERFACE
The SBC provides a PC/AT compatible bidirectional parallel port and supports enhanced
parallel port (EPP) mode and extended capabilities port (ECP) mode. The ECP mode is
IEEE 1284 compliant. The IRQ for the parallel port has BIOS selectable addressing.

NTERFACE
The SBC is compatible with a PS/2-type mouse. The mouse connection can be made by
using either the PS/2 mouse header or the bracket mounted mouse/keyboard mini DIN
connector. The mouse may be connected directly to the mini DIN connector or to the
"mouse" side of the "Y" adapter. Mouse voltage is protected by a self-resetting fuse.

EYBOARD
I
NTERFACE
The SBC is compatible with an AT-type keyboard. The keyboard connection can be
made by using either the keyboard header or the "keyboard" side of the "Y" adapter
plugged into the bracket mounted mouse/keyboard mini DIN connector. Keyboard
voltage is protected by a self-resetting fuse.

IMER
The watchdog timer is a hardware timer which resets the SBC if the timer is not
refreshed by software periodically. The timer is typically used to restart a system in
which an application becomes hung on an external event. When the application is hung,
it no longer refreshes the timer. The watchdog timer then times out and resets the SBC.
