Chapter 3 ardware Description
3.4 BIOS
The B OS on the M 7VGA motherboard provides the standard B OS
functions plus the following additional features:
1. ISA Plug and Play (PnP) Extension
Unlike PC cards that are Plug and Play, SA cards require setting
jumpers to resolve hardware conflicts. To make a computer system
PnP, an SA PnP standard is established and supported by new
operating systems, such as Windows 95. Under Windows 95, the
motherboard B OS must have an SA PnP extension to support new
SA PnP cards.
2. Power Management
The power management feature provides power savings by slowing
down the CPU clock, turning off the monitor screen and stopping
the HDD spindle motor. The B OS fully conforms to ACP
(Advanced Configuration and Power nterface) specification.
3.5 Onboard AGP Slot
The AGP (Accelerated Graphics Port) slot supports AGP compliant
VGA cards to achieve rich 3D and video graphics display. AGP is a
platform bus specification that enables 3D graphics capabilities
including support for z-buffering, alpha blending and faster texture
mapping.
3.6 Hardware Monitoring
The V A VT82C686A chip has a built-in hardware status monitoring
function that monitor several hardware parameters including power
supply voltages, fan speeds, and temperatures, which are very
important for a high-end computer system to work stable and properly.
This function is used together with the optional ntel LANDesk Client
Manager utility.
3.7 Onboard Multi-I/O
The multi- /O function is built in the V A VT82C686A chip supports a
keyboard controller, two serial ports, one parallel port, one floppy
controller and one rDA port. The serial ports are 16550 UART
compatible. The parallel port features high-speed EPP/ECP mode. The
floppy controller supports up to 2.88MB format.

3.8 Interrupt Request (IRQ) Lines
There are a total of 15 RQ lines available on the motherboard.
Peripheral devices use an interrupt request to notify the CPU for the
service required. The following table shows the RQ lines used by the
devices on the motherboard:
Level Function
RQ0 System Timer Output
RQ1 Keyboard
RQ2 nterrupt Cascade
RQ8 Real Time Clock
RQ9 Software Redirected to nt 0Ah
RQ10 Reserved
RQ11 Reserved
RQ12 Reserved
RQ13 Co-Processor
RQ14 Primary DE
RQ15 Secondary DE
RQ3 NTERRUPT
RQ4 Serial Port #1
RQ5 NTERRUPT
RQ6 Floppy Disk Controller
RQ7 Parallel Port #1
3.9 Onboard P I-IDE
The V A VT82C686A chip built-in’s PC - DE controller supports P O
mode 3/4 and bus mastering Ultra DMA/66 / Ultra DMA/33. The peak
transfer rate of P O mode 3/4 can be as high as 17MB/sec. Using
HDDs that support Ultra DMA/66, the peak transfer rate can reach
66MB/sec. There are two DE connectors - primary DE and secondary
DE. With two devices per connector, up to four DE devices can be
supported.
3.10 DMA hannels
There are seven DMA channels available on the motherboard; only
DMA2 is used by the floppy controller. n the case that ECP mode on
the parallel port is utilized, DMA1 or DMA3 will be used.

Figure 2: Jumper Location on the MI7VGA
14 MI7VGA User’s Manual

Chapter 4 Configuring the Motherboard
4.1 PU Frequency Setting
The M 7VGA uses jumper-free technology in configuring the
processor on the motherboard. The system automatically detects the
CPU bus speed, 66MHz or 100MHz and sets the multiplier, or ratio, to
3X. However, the bus speed can also be configured through the B OS
if the processor supports this feature. The B OS (under CPU Features
Setup) allows users to change the CPU bus speed multiplier (3X, 3.5X,
4X, 4.5X, 5X, 5.5X, 6X, 6.5X, 7X, 7.5X, 8X) to set the correct or
desired CPU frequency. The CPU bus speed multiplier will remain
unchanged if the CPU installed supports a fixed (only one) bus speed
multiplier.
IMPORTANT NOTE: t is possible that the system will not
boot if the CPU has been changed. When this happens, turn
off the computer by pressing the power button and turn it on
again by pressing the Insert key and the power button
simultaneously. (Note to press the Insert key until an image
appears on the screen.) When the system is turned on, press
the Delete key to enter B OS Setup and configure the CPU
speed.
4.2 lear MOS Select: JP5
Use JP5, a 3-pin header, to clear the contents of the CMOS RAM.
Do not clear the CMOS RAM unless it is absolutely necessary.
You will lose your password, etc.
JP5 Jumper Setting Function

pin 2-3: short Clear CMOS
NOTE: To clear CMO , the power connector should be
disconnected from the motherboard.
MI7VGA User’s Manual 15

Chapter 4 Configuring the Motherboard
4.3 JP3: SDRAM lock Select
Use JP3 to set the SDRAM clock. f the SDRAM on board is PC-
66 compatible (instead of PC-100), while your CPU bus speed is
100MHz, you have to short JP3. Failing to do so could lead to an
unstable system.
JP3 Setting Function
Open Run CPU Clock
Short Run AGP Clock
4.4 PU Host Frequency Force Selector: JP4
The M 7VGA is able to detect the host frequency (66MHz or 100MHz)
of the installed CPU. The JP4 jumper, however, can be set to OPEN to
override the detection and force the host frequency to run at 100MHz.
JP4 Function JP4 Function
