2.4 Memory Support
Up to 1GB of DDR 333 MHz SO-DIMM SDRAM is supported.
2.5 PCI Bus Interface Support
The GeodeLink PCI South Bridge (GLPCI_SB) provides a PCI interface for the Geode
CS5536 system chipset. The GLPCI_SB acts as a PCI master or PCI slave in providing
PCI transactions to and from the Geode CS5536 system chipset and the PCI bus. A
special serial interface to the Geode LX processor, the CPU Interface Serial (CIS) assists
in the transfer of information between the Geode CS5536 companion device and the
Geode LX processor.
PM-LX-800 CPU Card
The interface is compliant to PCI specification v2.2 and may operate at up to 66 MHz.
Within a PCI burst, zero wait state operation is achieved. The PCI interface supports
programmable IDSEL selection, and can handle inbound transactions immediately after
system reset.
2.6 Ethernet
The Realtek RTL8100C(L) is a single-chip Fast Ethernet controller. It is enhanced with an
ACPI (Advanced Configuration Power Interface) management function for PCI in order to
provide efficient power management for advanced operating systems with OSPM
(Operating System Directed Power Management). Realtek RTL8100C features are listed

Provides PCI clock run pin
Provides LED pins for network operation status indication
2.5/3.3V power supply with 5V tolerant I/Os
0.25µm CMOS process
2.7 Drive Interfaces
The PM-LX-800 can support the following drive interfaces:
1 x IDE connector supports two IDE devices
1 x Compact flash device
The PM-LX-800 is compliant to the ATA-6 specification. The IDE interface supports one
channel, that in turn supports two devices that can operate in PIO modes 0 to 4, MDMA
modes 0 to 2, or UDMA modes 0 to 5 (up to 100 MB/s).
2.8 Serial Ports
The PM-LX-800 CPU Board has three high-speed UART serial ports, configured as
COM1, COM2 and CN10. The serial ports have the following specifications.
16C550 UART with 16/32 byte selectable FIFO buffer
115.2Kbps transmission rate
2.9 Real Time Clock
256-byte battery backed CMOS RAM

2.10 System Monitoring
The PM-LX-800 motherboard is capable of self-monitoring various aspects of its operating
status including:
CPU, chipset, and battery voltage, +3.3V, +5V, and +12V
CPU and board temperatures (by the corresponding embedded sensors)
2.11 BIOS
The PM-LX-800 uses a licensed copy of Phoenix Award BIOS. The features of the flash
BIOS used are listed below:
SMIBIOS (DMI) compliant
PM-LX-800 CPU Card
Console redirection function support
PXE (Pre-Boot Execution Environment ) support
USB booting support
2.12 Operating Temperature and Temperature Control
The maximum and minimum operating temperatures for the PM-LX-800 motherboard are
listed below.
Minimum Operating Temperature: 0ºC (32°F)
Maximum Operating Temperature: 60°C (140°F)
A cooling heat sink is installed on the CPU. Thermal paste is smeared on the lower side of
the heat sink before it is mounted on the CPU.

2.14 PXE: Pre-Boot Execution Environment
PXE is an open industry standard developed by a number of software and hardware
vendors. IEI BIOS PXE feature allows a workstation to boot from a server on a network by
receiving a pre-OS agent prior to booting the operating system on the local hard drive.
