This chapter shows you how to do the hardware setup of this
mainboard .Besides the proper procedures listed below, this section
also discusses how to set the jumper switch settings and connectors on
the board. Go to Chapter 3 for BIOS setup after completing the above
procedures.
2.1 Memory Configuration
This mainboard uses three 168-pin 3.3V unbuffered type DIMMs of
8MB/16MB/32MB/64MB/128/256MB to form a memory size between
8MB and 768MB, and also, this mainboard supports Fast Page Mode
(FPM), Extended Data Output (EDO/3.3V), and Synchronous Dynamic
Random Access Memory (SDRAM) DIMMs.
