Overview

1.3.4 Expansion Slots
The board has three ISA and four PCI expansion slots. The ISA expansion
slots are the black parallel bars on the system board. The PCI slots are those
with white color and are shorter than the ISA slots. There are rows of golden
pins inside each slot that serve as a clutch to secure the contacts of the
expansion board. For information on how to install the expansion boards, see
Chapter 2.
1.3.5 DRAM Sockets
The system board has two 168-pin DRAM sockets that expand system memory
to a maximum of 128
B. These sockets accept single- and double-density
dual in-line memory modules (DIMMs) that support 3.3V Synchronous or 3.3V
Fast Page Mode (FPM)/Extended Data Out (EDO)-type DRAMs. Chapter 2
discusses the different memory configurations available.
1.3.6 Second-level Cache
The AP5V motherboard comes with either a 256-KB or a 512-KB pipeline-burst
second-level cache. This pipeline-burst cache improves system performance
by shortening the DRAM read prefetch time resulting to a faster data transfer
rate.
1.3.7 Two-channel PCI Mode 4 Enhanced IDE Interface
The AP5V board integrates a two-channel PCI mode 4 enhanced integrated
drive electronics (E-IDE) interface that allows the system to support four
E-IDE devices (including hard disks with more than 528-MB capacity) via two
onboard IDE connectors (see section 1.1 for the location of the connectors).
This feature offers users increased data storage capacity.
