 MS-6570E ATX Mainboard
Hard Disk Connectors: IDE1 & IDE2
The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 33/66/100/133
controller that provides 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, 120MB Floppy
(reserved for future BIOS) and other devices.
IDE1 (Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can connect a Master
and a Slave drive. You must configure second hard drive to Slave mode by setting the
jumper accordingly.
IDE2 (Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.IDE1 IDE2
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.

Hardware Setup
The motherboard provides the following jumpers 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 auto-
matically 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 instruc-
tions below to clear the data:
Jumpers
MSI 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.JBAT1

PCI 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:
AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert the AGP graphics card.  AGP is an interface
specification 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.
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
necessary hardware or software settings for the expansion card, such as jumpers,
switches or BIOS configuration.
The orange PCI slot (PCI5) also works as a communication slot, which
allows you to insert the communication card.The mainboard provides one AGP slot and five 32-bit PCI bus slots.

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: W7005MS V2.0 091096
where:
1st digit refers to BIOS maker as A=AMI(R); W=AWARD(R)
2nd - 5th digit refers to the model number.
6th - 7th digit refers to the customer, MS=all standard customers.
V2.0 refers to the BIOS version.
091096 refers to the date this BIOS is released.
