[A]      PS/2 Keyboard / Mouse Connectors

PS/2 device, likes some PS/2 keyboard and mouse, are all have a standard 6-pin round shape
connector. The benefit of PS/2 device is one of the serial port may be free for other serial device such
as writing table. On this motherboard, there are two on-board PS/2 connectors, one for keyboard and
one for mouse, which saves your money to buy any optional PS/2 connector module. If you are using a
PS/2 mouse or keyboard, you can simply plug into the corresponding connector without any jumper
setting.

[B]      USB Connectors

Universal Serial Bus (USB) is new interface standard for any I/O device “Outside the Box”. USB
makes your peripherals have a real plug and play (PnP) capabilities with up to 12Mb/sec data speed In
the coming soon, any external device connected to your computer will be standardized into USB
standard which are all have a special 4-pin rectangle shape connector. Therefore, with the Intel
chipset, this motherboard builds two USB connectors on-board for you future investment.

[C]      External I/O Connectors

Based on the ATX standard, two 9-pin serial ports and one 25-pin parallel port are now built on the
motherboard back panel, too! This design makes your motherboard’s installation more easily. The
parallel port can be BIOS configured into standard (SPP) mode, Enhanced Parallel Port (EPP) mode,
and a high speed Extended Capabilities Port (ECP) compatible mode.  EPP Mode requires a driver
provided by the peripheral manufacturer in order to operate correctly.

[D]      PENTIUM II

®

 CPU CARD Slot

The CPU card slot, slot 1, is a 242-pin slot design for PENTIUM II

, single edge contact cartridge,

along with a programmable voltage regulator for the CPU core. It provides users with a performance
upgrade path to PENTIUM II

®

 OverDrive technology. The motherboard built-in a switching voltage

regulator which supports from 2.1V to 3.5V PENTIUM II

 processors. The regulator makes use of the

VID capabilities to automatically adjust its voltage output to match that of the installed processor,
which eliminated the traditional jumper settings.

PENTIUM II

 

PROCESSOR CARD

The PENTIUM II

 processor integrates second level cache and cache controller that

was previously implemented on the motherboard.  The internal non-blocking L2 cache
on the processors card is 512k KB cache.

The PENTIUM II

®

 processor card maintains full backward compatibility with the

8086, 80286, Intel386

TM

, Intel486

TM

 and Pentium

®

 processors. It also has a numeric

coprocessor that significantly increases the speed of floating point operations, while
maintaining backward compatibility with the i486DX math coprocessor and complying
with ANSI/IEEE standard 754-1985.

[E]      Accelerated Graphic Port (AGP)

The AGP is compatible with the Accelerated graphics port specification. The AGP offers a much
higher throughput over the PCI bus does. PCI currently only supports 33Mhz can transport 133MB/s
at peak rates over its 32bit data bus. AGP is clocked with 66Mhz, which enables a peak rate of 266
MB/s at the classic so called ‘X1’ mode. If using the ‘X2’ mode, it can transport up to 532MB/s at
peak rate.
