							2-15 Hardware SetupHard Disk Connector: IDE1
The mainboard has 32-bit Ultra DMA 66/100 IDE controllers integrated in  the
chips Intel ICH7/ ICH7R, which supports PIO & Bus Master operation modes and it can
connect two Ultra ATA drives.
IDE1
The IDE1 can connect a Master and a Slave drive. You must configure second hard
drive to Slave mode by setting the jumper accordingly.MSI 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.IDE1 (blue)

							2-21 Hardware SetupThe motherboard provides the following jumper for you to set the computer’s
function. This section will explain how to change your motherboard’s function through
the use of jumpers.
Clear CMOS Jumper: JBAT1
There is a CMOS RAM on board that has a power supply from external battery
to keep the system configuration data. With the CMOS RAM, the system can automati-
cally boot OS every time it is turned on. If you want to clear the system configuration,
use the JBAT1 (Clear CMOS) Jumper to clear data. Follow the instructions below to
clear the data:JumpersMSI Reminds You...
You can clear CMOS by shorting 2-3 pin while the system is off.
Then return to 1-2 pin position. Avoid clearing the CMOS while the
system is on; it will damage the mainboard.JBAT11Keep Data1 3

This jumper is used to lock or unlock the boot block area on BIOS.  When
unlocked, the BIOS boot block area can be updated. When locked, the BIOS boot
block area cannot be updated.BIOS_WP1Locked

							2-22MS-7210 Micro-ATX MainboardSlots
PCI Express Slots (optional)
The PCI Express slots,  as a high-bandwidth, low pin count, serial, intercon-
nect technology, support Intel highest performance desktop platforms utilizing the
Intel Pentium 4 processor with HT Technology.
PCI Express architecture provides a high performance I/O infrastructure for
Desktop Platforms with transfer rates starting at 2.5 Giga transfers per second over
a PCI Express x1 lane for Gigabit Ethernet, TV Tuners, 1394 controllers, and general
purpose I/O. Also, desktop platforms with PCI Express Architecture will be designed
to deliver highest performance in video, graphics, multimedia and other sophisticated
applications. Moreover, PCI Express architecture provides a high performance graphics
infrastructure for Desktop Platforms doubling the capability of existing AGP 8x de-
signs with transfer rates of 4.0 GB/s over a PCI Express x16 lane for graphics
controllers.
You can insert the expansion cards to meet your needs. When adding or
removing expansion cards, make sure that you unplug the power supply first.The mainboard provides a PCI Express x16 slot, a PCI Express x4 slot and
three 32-bit PCI bus slots.

							2-23 Hardware SetupPCI Interrupt Request Routing
The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hard-
ware 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 SlotsPCI (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
necessary hardware or software settings for the expansion card, such as jumpers,
switches or BIOS configuration. 
						

							3-1 BIOS SetupChapter 3. BIOS 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 the system boot-
ing up, and requests you to run SETUP.
² You want to change the default settings for customized features.BIOS SetupMSI 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. Upon boot-up, the 1st line appearing after the memory count is the
BIOS version. It is usually in the format:
A7210IMS V1.0 100805 where:
1st digit refers to BIOS maker as A = AMI, W= AWARD.
2nd - 5th digit refers to the model number.
6th refers to the Intel Chipset
7th - 8th digit refers to the customer as MS = all standard customers.
V1.0 refers to the BIOS version.
100805 refers to the date this BIOS was released.
