Terminology usage
Attention: The term
Use of reserved areas can cause compatibility problems, loss of data, or permanent damage to the
hardware. When the contents of a register are changed, the state of the reserved bits must be preserved.
When possible, read the register first and change only the bits that must be changed.
reserved
describes certain signals, bits, and registers that should not be changed.
PC 300PL User
In this manual, some signals are represented in a small, all-capital-letter format (-ACK). A minus sign in
front of the signal indicates that the signal is active low. No sign in front of the signal indicates that the
signal is active high.
The use of the term

hex
indicates a hexadecimal number.
When numerical modifiers such as K, M, and G are used, they typically indicate powers of 2, not powers
of 10. For example, 1 KB equals 1024 bytes (210), 1 MB equals 1048576 bytes (220), and 1 GB equals
1 073 741 824 bytes (230).
When expressing storage capacity, MB equals 1 000 KB (1024000). The value is determined by counting
the number of sectors and assuming that every two sectors equals 1 KB.
Note: Depending on the operating system and other system requirements, the storage capacity available
to the user might vary.

modem. The menu for setting the Wake on Ring feature is in the Configuration/Setup Utility program.
Two options control this feature:
Serial Ring Detect: Use this option if the computer has an external modem connected to the serial
port.
Modem Ring Detect: Use this option if the computer has an internal modem.

The Pentium III microprocessor provides 256 KB L2 cache. The L2 cache ECC function is automatically
enabled if ECC memory is installed. If non-ECC memory is installed, the L2 cache ECC is disabled. (For
information on overriding the ECC memory settings, see the chapter about the Configuration/Setup Utility
program, in
http://www.intel.com on the World Wide Web.

Chapter 2. System board features
System memory
The system memory interface is controlled by the Intel 820 chip set. Rambus dynamic random access
memory (RDRAM) is standard.
The maximum amount of addressable system memory is 1 GB. For memory expansion, the system board
provides two Rambus inline memory module (RIMM) connectors. The system board also supports PC700
memory and PC800 memory RIMMs in sizes of 64 MB, 128 MB, 256 MB, and 512 MB. The amount of
memory that is preinstalled varies by model.
The following information applies to system memory:
ECC or non-ECC RDRAM is standard.
The maximum height of memory modules is 6.35 cm (2.5 in.).
Each memory connector supports a maximum of 512 MB of memory, when available.
Install only ECC RIMMS to enable ECC. If you use ECC and non-ECC memory together, all installed
memory will function as non-ECC memory.
RIMM connectors do not support dual inline memory modules (DIMMs).
Any connector that does not have a RIMM installed must have a
continuity RIMM
(C-RIMM), a module
that looks like a RIMM but has no memory on it. A continuity RIMM is used to continue the
connection on a RIMM connector that does not have memory installed in it.
Use PC700 or PC800 RIMMs only.
Maximum system memory can be auto-detected and auto-configured using serial presence detect and
configuration interface (BIOS specific).
The following table shows the possible configuration of RIMMs and continuity RIMMs that can be used in
the PC 300PL Personal Computer.

Chapter 2. System board features
PCI bus
The fully synchronous 33 MHz PCI bus originates in the chip set. Features of the PCI bus are:
Integrated arbiter with multitransaction PCI arbitration acceleration hooks
Zero-wait-state, microprocessor-to-PCI write interface for high-performance graphics
Built-in PCI bus arbiter with support for up to five masters
Microprocessor-to-PCI memory write posting with 5-Dword-deep buffers
Conversion of back-to-back sequential microprocessor-to-PCI memory write to PCI burst write
PCI-to-DRAM posting 18 Dwords
PCI-to-DRAM up to 100+ MB/sec bandwidth
Multitransaction timer to support multiple short PCI transactions within one PCI ARB cycle
PCI 2.2 compliant
Delayed transaction
PCI parity checking and generation support
IDE bus master interface
The system board incorporates a PCI-to-IDE interface that complies with the
Extensions
The bus master for the IDE interface is integrated into the I/O hub of the Intel 820 chip set. The chip set
is PCI 2.2 compliant. It connects directly to the PCI bus and is designed to allow concurrent operations on
the PCI bus and IDE bus. The chip set is capable of supporting PIO mode 0–4 devices and IDE DMA
mode 0–3 devices, ATA 66 transfers up to 66 megabytes per second (MBps).
.
AT Attachment Interface with
The IDE devices receive their power through a four-position power cable containing +5, +12, and ground
voltage. When devices are added to the IDE interface, one device is designated as the master device and
another is designated as the slave or subordinate device. These designations are determined by switches
or jumpers on each device. There are two IDE ports, one designated Primary and the other Secondary,
allowing for up to four devices to be attached. The total number of physical IDE devices is determined by
the mechanical package.
For the IDE interface, no resource assignments are given in the system memory or the direct memory
access (DMA) channels. For information on the resource assignments, see “Input/output address map” on
page 36 and Figure 38 on page 40 (for IRQ assignments).
Two connectors are provided on the riser card for the IDE interface. For information on the connector pin
assignments, see “IDE connectors” on page 30.
USB interface
Universal Serial Bus (USB) technology is a standard feature of the computer. The system board provides
the USB interface with two connectors integrated into the ICH1 (I/O hub) in the chip set. A USB-enabled
device can attach to a connector, and if that device is a hub, multiple peripheral devices can attach to the
hub and be used by the system. The USB connectors use Plug and Play technology for installed devices.
The speed of the USB is up to 12 MB/sec with a maximum of 127 peripheral devices. The USB is
compliant with Universal Host Controller Interface Guide 1.0.

Chapter 2. System board features
The video subsystem supports all video graphics array (VGA) modes and is compliant with super video
graphics array (SVGA) modes and Video Electronics Standards Association (VESA) 1.2. Some enhanced
features include:
Video subsystem on a chip, including 2D, 3D, and a video port
66 MHz AGP system bus interface with 2X or 4X mode
Sideband signaling (some models only)

64-bit, 125 MHz SDRAM or 166 MHz SGRAM interface
Plug and Play support
Advanced Power Management support
Color space conversion
Hardware scaling
The integrated graphics memory controller subsystem supports the VESA Display Data Channel (DDC)
standard 1.1 and uses DDC1 and DDC2B to determine optimal values during automatic monitor detection.
The video subsystem has the following resource assignments:
Figure 2. Video subsystem resources
Resource Assignment
ROM Hex C0000–C7FFF (32KB)
RAM Hex A0000–BFFFF
I/O (hex) VGA registers: Attributes 0–14, CRT controller 0–18/22/24/26, CRTC Extension 0-6, DACSTAT, FEAT, GCTL
0-8, INSTS0-1, MISC, Sequencer 0-4, DAC
IRQ PCI interrupt 1 (automatically assigned to IRQ 0BH by POST or can be disabled in the Configuration/Setup
Utility)
DMA None
For further information on resource assignments, see Appendix B, “System address maps” on page 36
and Appendix C, “IRQ and DMA channel assignments” on page 40.
The PC 300PL Personal Computer supports the following video subsystem modes:
