1 Motherboard Features
This chapter describes the features of the DK440LX motherboard. The remaining chapters explain
how to:
• Add or upgrade components like processors or memory
• Use the BIOS Setup program and the SCSISelect†utility to modify the motherboard’s
configuration
• Upgrade the BIOS
Figure 1 shows the location of components on the motherboard and Figure 2 shows the details of
the back panel connectors.
Microprocessor
The DK440LX motherboard supports 233 MHz, 266 MHz, and 300 MHz Pentium®II processors.
The motherboard is designed to operate with one or two processors. Processors are not included
with the DK440LX motherboard and must be purchased separately.
Each processor is packaged in a Single Edge Contact (S.E.C.) cartridge. The S.E.C. cartridges
mount in a dual-processor retention mechanism which is provided with Intel boxed motherboards.
Microprocessor Upgrades
If your motherboard has one processor, you can upgrade the computer by replacing this processor
with a faster processor or by installing a second processor. If your motherboard has two
processors, you can upgrade the computer by installing two faster processors.
Computers with two processors must have an operating system (such as Windows†NT†or UNIX†)
that supports multiple processors.
If you are installing two processors, the following values must be identical for both processors:
• L2 cache size and type (ECC or non-ECC)
• Operating voltages
• Maximum bus and core frequencies
The core stepping value may differ by one step, such as C0 to C1. These values can be determined
by checking the parameters of the s-spec number. The s-spec number is a five-character code, for
example, SL28R, printed on the top edge of the S.E.C.
For information about s-spec parameters, refer to the Pentium II processor quick reference guide at
the Intel developer’s web site.
CAUTION
If the operating voltages do not match, the computer will not boot.

Motherboard Features

Main Memory
The motherboard has four sockets for installing dual in-line memory modules (DIMMs). The
motherboard supports both extended data out (EDO) DRAM and synchronous DRAM (SDRAM).
The motherboard can operate with a minimum of 16 megabytes (MB) of memory. Maximum
memory size is 512 MB with SDRAM and 1 GB with EDO DRAM. To install memory, see
Chapter 2.
Second-level Cache Memory
The second-level cache is located on the substrate of the S.E.C. cartridge. The ECC cache includes
burst pipelined synchronous static RAM (BSRAM) and tag RAM. There are four BSRAM
components totaling 512 KB in size. Only up to 512 MB of system memory is cacheable.
PCI Enhanced IDE Interface
The PCI enhanced IDE interface handles the exchange of information between the processor and
peripheral devices like hard disks and add-in cards inside the computer. The interface supports:
• Up to four IDE devices such as hard drives
• ATAPI devices
• PIO mode 3 and PIO mode 4 devices
• Up to four PCI cards or up to two ISA cards and three PCI cards
• Logical block addressing (LBA) of hard drives larger than 528 MB and extended cylinder head
sector (ECHS) translation modes
LS-120 Diskette Support
The motherboard supports LS-120 diskette technology through its IDE interface. LS-120 diskette
technology enables users to store 120 MB of data on a single, 3.5-inch removable diskette. LS-120
technology is backward (both read and write) compatible with 1.44 MB and 720 KB DOS-
formatted diskettes and is supported by Windows 95 and Windows NT operating systems.
The motherboard allows connection of an LS-120 compatible drive and a standard 3.5-inch diskette
drive. If an LS-120 drive is connected to an IDE connector and configured as the A drive and a
standard 3.5-inch diskette drive is configured as the B drive, the standard diskette drive must be
connected to the diskette drive cable's "A" connector (the connector at the end of the cable). The
LS-120 drive can be configured as a boot device in the BIOS Setup program.
