SYSTEM MOTHERBOARD
This chapter describes the features of the system
motherboard, setting jumpers and other relevant
information.
Microprocessor
This motherboard supports 233 MHz and 266 MHz Intel
Pentium
II processors with MMX
technology and 256
KB or 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 (DRAM)
The motherboard supports up to 256 MB of DRAM.
DRAM is implemented through four 72-pin SIMM sockets.
The motherboard contains four SIMM sockets. To add
memory to the motherboard, see Chapter 3. For the
motherboard’s main memory map, see Chapter 5.
Memory error checking and correction is supported with
parity or ECC SIMMs. Parity or ECC SIMMs are
automatically detected.
However, the user must enter Setup to configure SIMMs 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.
