I. Introduction
The Santafe-KM mATX motherboard offers a time-to-market consumer desktop solution featuring the AMD
SocketA processor with the 200MHz front side bus and VIA KM133 chipset. The Santafe-KM motherboard was
designed to have highly minimized system cost, so it is a good solution for a value PC system. Integrated AGP
graphics controller core and PCI audio solution with AC97 Codec make the expensive graphic and audio add-in
cards unnecessary. After all, the Santafe-KM motherboard is a good solution for the PC users with an affordable
price.

2. Upgradeability
2-1. Processor
Santafe-KM motherboard provides the 462pin SocketA which supports Athlon & Duron and is not backward
compatible with ZIF socket-7 processors. The voltage regulator on the motherboard is programmed to output
the required voltage by the processor itself through the processor’s VID pin.
q Suppported AMD SocketA Processors : Athlon, Duron
2-2. Memory
Santafe-KM motherboard has two, dual inline memory module (DIMM), minimum 16MB to maximum 256MB
memory size. The BIOS detects the memory type, size, and speed through SMBUS interface between the core
chipset and DIMM module automatically.
The motherboard supports the following memory features
• 3.3V and unbuffered 168-pin DIMM
Voltage detection
3.3V Version 5V Version
Unbuffered detection
Unbuffered Buffered
• DRAM interface synchronous with host CPU (200 MHz)
Supports SDRAM memory types
•
• Different DRAM types may be used in mixed combinations
• Different DRAM timing for each bank

2-3 BIOS
q Flash memory organization
The motherboard uses a Phoenix BIOS, which is stored in the flash memory and can be upgraded using a disk-
based program. An old version of the BIOS can be updated to the newer version using the Flash Memory
Update utility in a floppy diskette.
Address (Hex) Size Functional description
FFFFC000 – FFFFFFFF 16KB Main BIOS block#1
FFFFA000 – FFFFBFFF 8KB ESCD
FFFC0000 – FFF9FFFF 232KB Main BIOS block#2
<Simplified flash memory address map>
q On-board device management
The BIOS enables or disables the devices on the motherboard with reference to the values of the contents in
CMOS setup menu. User can also disable the CMOS setup by setting the corresponding jumper (described in
III-1 Motherboard Jumper Setting section).

VIA VT82C694Z supports up to five REQ and GNT signals.
2-5. Advanced Configuration and Power Interface (ACPI)
The motherboard and system BIOS support the ACPI that requires an ACPI-aware operating system such as
Windows-NT 5.0 or Windows 98/ME. ACPI feature include
• Plug and play functionality normally contained in the BIOS
• A soft-off feature that enables operating system to power off the computer
• Indication LED for normal mode (Green) and suspend mode (Blinking Green) but this function is
dependent on the LED logic or BIOS control.
• Support multiple wakeup events
