functions:
• Basic 10/100 Ethernet LAN connectivity
• Support for RJ-45 connector with status indicator LEDs
• Programmable transit threshold
• Configurable EEPROM that contains the MAC address

On (brighter and pulsing) The computer is communicating with another computer on
the LAN.
Enhanced IDE Interface
The ICH4’s IDE interface handles the exchange of information between the processor and
peripheral devices like hard disks, CD-ROM drives, and Iomega Zip* drives inside the computer.
The interface supports:
• Up to four IDE devices (such as hard drives)
• ATAPI devices (such as CD-ROM drives)
• Older PIO Mode devices
• Ultra DMA-33 and ATA-66/100 protocols
• Laser Servo (LS-120) drives
Expansion Slots
Desktop Board D845GVFN has three PCI bus add-in card connectors.
