4-10 System Board
The FLASH ROM allows the system and video BIOS to be upgraded with the BIOS Update
Utility, without having to physically remove the ROM (see Section 2 for further information on
the BIOS Update Utility). The FLASH ROM supports the reprogramming of the system BIOS
and the video BIOS.
System Memory
The system comes with between 64 MB and 512 MB of RDRAM installed in two RIMM
sockets on the system board.
The RIMM sockets accept 184-pin, 64-, 128-, and 256-MB RIMMs. See the “Sample RIMM
Memory Upgrade Paths” earlier in this section for a list of supported RIMMs.
Plug and Play
The system comes with a plug and play BIOS in support of plug and play technology. Plug and
play simplifies setup procedures for installing plug and play expansion boards. With plug and
play, adding a plug and play expansion board is done by turning off the system, installing the
board, and turning on the system. There are no jumpers to set and no system resource conflicts
to resolve. Plug and play automatically configures the board. (Some plug and play devices might
need to be jumpered if used in a system running the Windows NT operating system.
PCI/IDE Ports
The system board has two high-performance PCI/IDE ports: a primary port and a secondary
port. The primary PCI/IDE port has an enhanced IDE interface that supports PIO Mode 4
devices with 66 MB per second maximum burst rate data transfers on the high-performance
Ultra DMA bus. The primary port supports Ultra DMA/66.
The installed hard drive is connected as a master device on the primary PCI/IDE port. The
installed CD-ROM drive or DVD-ROM drive is connected to the secondary PCI/IDE port as a
master device. The hard drive is connected to the primary port with a three-connector Ultra
DMA/66 40-pin, 80-conductor cable. The CD-ROM or DVD-ROM is connected to the
secondary port with a standard three-connector IDE cable.
Parallel Interface
The system has a 25-pin bidirectional parallel port on the system board. Port specifications
conform to the IBM-PC standards. The port supports Enhanced Capabilities Port (ECP) and
Enhanced Parallel Port (EPP) modes for devices that require ECP or EPP protocols. The
protocols allow high-speed bi-directional transfer over a parallel port and increase parallel port
functionality by supporting more devices.
The BIOS has automatic ISA printer port sensing that works with most devices. If the BIOS
detects an ISA printer port mapped to the same address, the built-in printer port is disabled.
(Verify in the BIOS Setup that printer ports mapped to the same address are enabled or disabled
appropriately.) The BIOS also sets the first parallel interface port it finds as LPT1 and the
second port it finds as LPT2. The interrupt is set at IRQ7 via the BIOS Setup Utility. Software-
selectable base addresses are 378h, 278h, and 3BCh.
Sets of I/O addresses for the parallel port are given in the following table (see Section 2,
“System Configuration,” for interrupt levels). This is a list of all possible configurations; the
parallel port uses only one set.
