2.6 Network
The GL8"5E supports an optional "0/"00 Ethernet controller based around the controller integrated
within the chipset and an Intel GD82562ET transceiver. An RJ45 connector located on the rear
panel integrates two LED indicators to provide link status information. The list below describes the
features provided.
• IEEE 802.3 "0Base-T and "00Base-TX compatible
• 32-bit bus-mastering PCI device
• Jumper-less configuration
• RJ45 with two integral LEDs showing line activity, link integrity and line speed
The operation of the two indicators is described in the table below.
LED color LED state Indicates
Off "0Mbps link speedGreen
On "00Mbps link speed
Off No link is established
Steady on Link is established but there is no communication activity
Yellow
Blinking Link is established and communication activity is detected
2.7 IDE Drives
Two independent bus-mastering IDE interfaces are provided, each supporting ATA modes up to
UltraATA/"00. The following drive types are supported.
• ATA hard disks up to UltraATA/"00 speeds
• ATAPI devices such as CD-ROMs
• LS"20 drives
The BIOS supports logical block addressing (LBA) and extended CHS translation modes for hard
disks. When booting from LS"20 drives, the correct mode (floppy or hard disk) must be chosen in
Setup. The BIOS supports both automatic and manual determination of ATA cable type (80 - or 40-
pin) to support UltraATA/66 or ATA/"00 drives.
2.8 Diskette Drives
The diskette drive interface supports a maximum of two drives. The drives should be 2- or 3-mode
3.5-inch devices supporting 720kB, ".2MB or ".44MB formats. The controller is located at I/O
addresses 3F0-3F7h and uses IRQ6.
2.9 Standard PC I/O
The standard PC I/O functions serial ports, parallel ports, keyboard and mouse ports and diskette
drive controller are provided via a National Semiconductor PC87366 Super I/O (SIO) device
attached to the low pin count (LPC) bus from the chipset ICH2. In addition, this device provides
system monitoring and fan control functions and general-purpose I/O lines.
