System Board
The system board contains the Intel Celeron or Pentium III processor mounted in a Slot 370
socket, system DIMM memory mounted in up to two sockets, and an Intel 810E chipset. The
chipset incorporates the 82810E Graphics Memory Controller Hub (GMCH), 82801 I/O
Controller Hub (ICH), integrated Audio-Codec 97 Controller, 82802 Firmware Hub (FWH), and
Dynamic Video Memory Technology (DVMT).
External connectors on the system board include one serial connector, a parallel connector, two
USB ports, keyboard port, mouse port, LAN port, and external audio connectors.
The system board supports the standard 1.44-MB diskette drive, the standard IDE hard drive,
and a CD-ROM drive or DVD-ROM drive.
For further information on the system board, see Section 4, “System Boards.”
System Memory
The system supports up to 512 MB of high-speed memory in two DIMM sockets on the system
board. Supported are 168-pin, 100-MHz SDRAM modules in 64-, 128-, and 256-MB unbuffered
configurations.
The memory modules can be installed in one or two sockets, can vary in size between sockets,
and can be single- and double-sided DIMMs.
