MS7122A Form-Factor
The MS7122A is designed with ATX form factor - the new industry standard of
chassis. MicroATX form factor is essentially a Baby-AT baseboard rotated 90
degrees within the chassis enclosure and a new mounting configuration for the
power supply. With these changes the processor is relocated away from the
expansion slots, allowing them all to hold full length add-in cards. ATX defines a
double height aperture to the rear of the chassis which can be used to host a wide
range of onboard I/O. Only the size and position of this aperture is defined,
allowing PC manufacturers to add new I/O features (e.g.; TV input, TV output,
joystick, modem, LAN, etc.) to systems. This will help systems integrators
differentiate their products in the marketplace, and better meet your needs.
•By integrating more I/O down onto the board and better positioning the hard
drive and floppy connectors material cost of cables and add-in cards is
reduced.
•By reducing the number of cables and components in the system, manufac-
turing time and inventory holding costs are reduced and reliability will
increase.
•By using an optimized power supply, it's possible to reduce cooling costs and
lower acoustical noise. An ATX power supply, which has a side-mounted fan,
allows direct cooling of the processor and add-in cards making a secondary
fan or active heatsink unnecessary in most system applications.

Power-On/Off (Remote)
The MS7122A has a single 20-pin connector for ATX power supplies. For ATX
power supplies that support the Remote On/Off feature, this should be connected
to the systems front panel for system Power On/Off button. The systems power
On/Off button should be a momentary button that is normally open.
The MS7122A has been designed with “Soft Off" functions. You can turn Off the
system from one of two sources: The first is the front panel Power On/Off
button, and the other is the "Soft Off" function (coming from the MS7122A’s
onboard circuit controller) that can be controlled by the operating system. Win-
dows 95 will control this when the user clicks that they are ready to Shutdown the
system.

FEATURES
MS7122A Features:
•MS7122A is based on the Mendocino Processor operating at 300 ~
466MHz on PGA370. The board is configured by an ESSJ (Easy-Setting-
Single-Jumper) to match your CPU clock speed.
•Designed with VIA Apollo Pro PCIset.
•Supports up to 768MB of DRAM (minimum of 8 MB) on board (please
see Section 3-2).
•MS7122A will support Error Checking and Correcting (ECC) when using
parity SDRAM memory modules. This will detect multiple bit errors and
correct 1-bit memory errors.
•Supports (1) 16 bit ISA slots, (4) 32 bit PCI slots, (1) AGP slot, (1) AMR
slot and provides (2) independent high performance PCI IDE interfaces
capable of supporting PIO Mode 3/4 and Ultra DMA 33/66 devices.
The MS7122A supports (4) PCI Bus Master slots and a jumperless PCI
INT# control scheme which reduces configuration confusion when plugging
in PCI card(s).
•Supports ATAPI (e.g. CD-ROM) devices on both Primary and Secondary
IDE interfaces.
•Designed with on chip Multi I/O: (1) floppy port, (1) parallel port (EPP,
ECP), and (2) serial ports (16550 Fast UART).
Note: Japanese “Floppy 3 mode” is also supported
•Features Award Plug & Play BIOS. With Flash Memory you can always
upgrade to the current BIOS as they are released.
•MS7122A utilizes a Lithium battery which provides environmental protec
tion and longer battery life.
•Supports the (4) Universal Serial Bus (USB) Ports. The onboard
VT82C686A chip provides the means for connecting PC peripherals such
as; keyboards, joysticks, telephones, and modems.
