CPU
Supports AMD® Socket 462 series CPU with 200MHz and 266MHz EV6 Bus designed for Socket 462 technology.
Athlon: 600MHz~1.4GHz
Duron: 600MHz~1.2GHz
AthlonXP: 1500+(1.33GHz)~2800+(2.25GHz)
Chipset
The VIA Apollo KM266 consists of the KM266 V-Link DDR Host system controller and the VT8235 (or VT8233A SB for MK77M)
highly integrated V-Link Client PCI/LPC controller. The Host system controller provides superior performance between the CPU,
SDRAM, AGP bus, and V-Link interface with pipelined, burst, and concurrent operation. The VT8235 (or VT8233A for MK77M)
V-Link Client controller is a highly integrated PCI/LPC controller. Its internal bus structure is based on 66MHz PCI bus that
provides 2x bandwidth compare to previous generation PCI/ISA bridge chips. The VT8235 (or VT8233A for MK77M) integrated
Client V-Link controller with 200/266MB/s bandwidth between Host/Client V-Link interface, provides a V-Link-PCI and
V-Link-LPC controller. Of three PCI slots provided, MK77M / MK77M II supports all three master PCI slots with arbitration and
decoding for all integrated functions and LPC bus.

MMKK7777MM // MMKK7777MM IIII OOnnlliinnee MMaannuuaall
Ultra DMA 66/100/133 Bus Master IDE
Comes with an on-board PCI Bus Master IDE controller with two connectors that supports four IDE devices in two channels,
supports
Ultra DMA
66/100/133, PIO Modes 3 and 4 and Bus Master IDE DMA Mode 4, and supports Enhanced IDE devices.
Expansion Slots
Including three 32-bit/33MHz PCI and one AGP 4X slots. The PCI local bus throughput can be up to 132MB/s. The Accelerated
Graphics Port (AGP) specification provides a new level of video display sophistication and speed. The AGP video cards support
data transfer rate up to 1056MB/s. As MK77M / MK77M II includes one AGP expansion slot for a bus mastering AGP graphic
card, For AD and SBA signaling, MK77M / MK77M II can support 133MHz 2X/4X mode.
Memory
With VIA Apollo KM266 chipset, the MK77M / MK77M II can support Double-Data-Rate (DDR) RAM. The DDR RAM interface

This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards,
and other components. Always observe the following precautions before you install a system
component.
1. Do not remove a component from its protective packaging until you are ready to install it.
2. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a
component. If a wrist strap is not available, maintain contact with the system unit throughout
any procedures requiring ESD protection.

You can clear CMOS to restore system default setting. To clear the CMOS, follow the procedures below.
1. Turn off the system and unplug the AC power.
2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pin 1 & pin 2.
5. Connect ATX power cable back to connector PWR2.

This motherboard supports AMD® Athlon and Duron Socket 462 series CPU. Be careful of CPU orientation when you plug it into
CPU socket.
1. Pull up the CPU socket lever and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut edge on the
CPU upper interface. Match Pin 1 and cut edge, then insert the CPU into
the socket.

This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, if you are not overclockers, we
recommend you to set it to the default setting. Additionally, this motherboard also provides “1MHz Stepping Adjustment”
feature for overclockers to adjust CPU FSB frequency via BIOS setup program. Based on the CPU type, the adjustment range
has two levels: 100~132 (FSB=100, such as Athlon 800), 133~166 (FSB=133, such as Athlon 1000) MHz for your choosing. You
may also choose a specific FSB frequency ranging from 100~117 (say, 105, 110, 115 for example) and 120~156 with reference
to a frequency table in BIOS setup program. If you fix the CPU FSB frequency by JP21, the “1MHz Stepping Adjustment” range
will be changed and following your JP21 setting.
Warning: High CPU
