PCI/ISA System Board

vIntroduction
The G586OPC system board offers several advanced
features integrated into the system board. Its design is
based on the new Peripheral Component Interconnect
(PCI) local bus and Industry Standard Architecture
(ISA) standards.
The G586OPC provides a 321-pin Zero Insertion Force
(ZIF) CPU socket for PentiumTM processors running at
75MHz, 90MHz, 100MHz, 120MHz, 133MHz or
150MHz frequency. This ZIF socket allows users to
easily upgrade their CPUs. It also provides a VRM
(Voltage Regulation Module) header allowing you to
upgrade to future low-voltage CPUs.
The G586OPC is equipped with three PCI slots, three
ISA slots and one shared PCI/ISA slot.
The G586OPC board has two bus master PCI IDE
connectors. Bus mastering reduces CPU use during disk
transfer. The system board is also equipped with two
NS16C550A-compatible serial ports, an SPP/EPP/ECP
parallel port, a floppy disk drive controller, one PS/2
mouse port and one PS/2 keyboard connector.
The G586OPC can support 2MB to 128MB of memory
using 256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36 and
8Mx36 72-pin SIM modules.
