MSI K8mm3v Manual

							2-15 Hardware SetupHard Disk Connectors: IDE1 & IDE2
The mainboard provides a 32-bit Enhanced PCI IDE and Ultra DMA 33/66/100/133
controller that supports PIO mode 0 ~ 4, Bus Master, and Ultra DMA 33/66/100/133
function. You can connect up to four hard disk drives, CD-ROM drives, 120MB floppy
disk drive (reserved for future BIOS), and other devices.
IDE2 IDE1MSI Reminds You...
If you install two hard disks on cable, you must configure the second
drive to Slave mode by setting its jumper. Refer to the hard disk
documentation supplied by hard disk vendors for jumper setting
instructions.
Serial Port Header: JCOM1 (Optional)
The mainboard offers one 9-pin header as serial port. The port is a 16550A high
speed communication port that sends/receives 16 bytes FIFOs. You can attach a
serial mouse or other serial device directly to it.

							2-22MS-7181 Micro-ATX MainboardSlots
PCI (Peripheral Component Interconnect) Slots
The PCI slots allow you to insert the expansion cards to meet your needs. When
adding or removing expansion cards, make sure that you unplug the power supply
first. Meanwhile, read the documentation for the expansion card to make any neces-
sary hardware or software settings for the expansion card, such as jumpers,
switches or BIOS configuration.AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert the AGP graphics card. AGP is an interface speci-
fication designed for the throughput demands of 3D graphics. It introduces a 66MHz,
32-bit channel for the graphics controller to directly access main memory. The slot
supports 8x/4x AGP card. The motherboard provides one AGP slot and three 32-bit PCI bus slots.PCI Interrupt Request Routing
The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines
over which devices can send interrupt signals to the microprocessor.  The PCI IRQ
pins are typically connected to the PCI bus INT A# ~ INT D# pins as follows:
Order 1Order 2Order 3Order 4
PCI Slot 1INT A#INT B#INT C#INT D#
PCI Slot 2INT B#INT C#INT D#INT A#
PCI Slot 3INT C#INT D#INT A#INT B# 
						

							3-1 BIOS SetupChapter 3. BIOS SetupBIOS SetupThis chapter provides information on the BIOS Setup program
and allows you to configure  the system for optimum use.
You may need to run the Setup program when:
² An error message appears on the screen during system boot up, and
requests you to run SETUP.
² You want to change the default settings for customized features.MSI Reminds You...
1. The items under each BIOS category described in this chapter are
under continuous update for better system performance.
Therefore, the description may be slightly different from the latest
BIOS and should be held for reference only.
2. While booting up, the BIOS version is shown in the 1st line ap-
pearing after the memory count. It is usually in the format:
example: W7181VMS V2.0 010306
where:
1st digit refers to BIOS maker as A=AMI(R); W=AWARD(R)
2nd - 5th digit refers to the model number.
6th digit refers to VIA chipset.
7th - 8th digit refers to the customer, MS = all standard customers.
V2.0 refers to the BIOS version.
010306 refers to the date this BIOS is released. 
						

							3-2MS-7181 Micro-ATX MainboardEntering Setup
Power on the computer and the system will start POST (Power On Self Test) process.
When the message below appears on the screen, press  key to enter Setup.
Press DEL to enter SETUP
If the message disappears before you respond and you still wish to enter Setup,
restart the system by turning it OFF and On or pressing the RESET button. You may
also restart the system by simultaneously pressing , , and  keys.
Selecting the First Boot Device
You are allowed to select the 1st boot device without entering the BIOS setup utility
by pressing . When the same message as listed above appears on the screen,
press  to trigger the boot menu.
The POST messages might pass by too quickly for you to respond in time. If so, restart
the system and press  after around 2 or 3 seconds to activate the boot menu
similar to the following.
The boot menu will list all the bootable devices. Select the one you want to boot from
by using arrow keys, then press . The system will boot from the selected
device.  The selection will not make changes to the settings in the BIOS setup utility,
so next time when you power on the system, it will still use the original first boot
device to boot up.Select First Boot Device
