SYSTEM MOTHERBOARD
This chapter describes the features of the system
motherboard, setting jumpers and other relevant
information.
Microprocessor
This motherboard supports 233 MHz, 266 MHz and 300
MHz Intel Pentium
II processors with MMX
technology
and 512 KB secondary (L2) cache.
The Pentium II processor is packaged in a Single Edge
Contact (S.E.C.) cartridge that mounts in the Slot 1
processor connector on the motherboard.
Main Memory (SDRAM)
The motherboard supports up to 384MB of SDRAM.
SDRAM is implemented through three 168-pin DIMM
sockets. The motherboard contains three DIMM sockets. To
add memory to the motherboard, see Chapter 4. For the
motherboard’s main memory map, see the ‘Motherboard
Resources’ section later in this chapter.
Memory error checking and correction is supported with
parity or ECC DIMMs. Parity or ECC DIMMs are
automatically detected. However, For ECC operation to be
available, all installed memory must be ECC and the user
must enter Setup to configure DIMMs for either parity or
ECC operation. Parity memory will detect single-bit errors.
ECC memory will detect multi-bit errors and correct single-
bit errors.
Errors may be generated by a defective memory module,
mixing different speed memory modules, or by DMA or
memory conflicts.
