CPU
The CHIP4e+ incorporates an AMD®5x86 processor with a CPU clock that runs
quadrupled at 133 MHz with a 33 MHz external bus. The unified 16 Kbyte write-
back cache technology minimizes the time the CPU core spends waiting for data or
instructions, accelerating business and multimedia applications.
PCI Bus Interface
The FinALI chipset integrates a high-performance CPU-to-PCI interface capable of
accelerated data transfers. The interface allows 32-bit master and slave PCI devices.
SVGA Graphics Controller
The PCI bus SVGA graphics controller supports CRTs and flat-panel displays with 1
Mbyte video DRAM. It supports resolutions of 640x480 with 16M colors; 800x600
with 64K colors; and 1024x768 with 256 colors.
Fast IDE controller
The high-speed local bus IDE controller supports programmed I/O (PIO) modes 0-4.
It also provides 4x32-bit read-ahead buffer and 4x32-bit write-post buffer support to
enhance IDE performance.
Caution
The IDE controller supports enhanced PIO modes, which reduce the
cycle times for 16-bit data transfers to the hard drive. Check with your
drive manual to see if the drive you are using supports these modes. The
higher the PIO mode, the shorter the cycle time. As the IDE cable length
increases, this reduced cycle time can lead to erratic operation. As a
result, it is in your best interest to keep the IDE cable as short as
possible.
Select the PIO modes in the BIOS setup (refer to Chapter 3). The
autoconfigure classifies the drive connected if the drive supports the
auto ID command. If you experience problems, change the PIO to
standard.
Ethernet Controller
The CHIP4e+ contains a state-of-the-art 10BASE-T/100BASE-TX Ethernet
controller with a 32-bit PCI bus-mastering interface to support 100-Mbits per second
bus transfers. The controller serves as both a PCI master and slave. The Ethernet
connector (ETHER1) provides auto-sensing for 10BASE-T and 100BASE-TX
connections.

On-board Memory
DRAM
The CHIP4e+ has one 72-pin SIMM memory site, providing up to 64 Mbytes of
DRAM. Populate the memory site with standard fast page mode memory or extended
data out memory (EDO). EDO memory improves DRAM read performance.
Flash BIOS
The CHIP4e+ board provides a Flash BIOS location for system and video ROM.
Table 0-1 describes the Flash memory map.
Table 0-1. Flash Memory Map
Device Address Software System Address
60000-7FFFFh System BIOS E0000-FFFFFh (also FFFE0000-
FFFFFFFFh)
10000-5FFFFh Undefined
00000-0FFFFh Video BIOS C0000-CFFFFh
Non-Volatile SRAM or DOC2000 (optional)
Socket U25 is a 32-pin ROM site that provides an option for installing non-volatile
SRAM or DiskonChip 2000 modules. You must specify which option you are
installing on the BIOS Setup Advanced menu (refer to Chapter 3 for more
information on the BIOS Setup menus).
Note
You may only install SRAM or DOC2000 in socket U25; you cannot
install both.
Non-volatile SRAM contains a built-in battery and battery backup circuitry. Battery
life is approximately seven years in the absence of VCC. Socket U25 supports
32Kx8 and 128Kx8 memory sizes. BIOS defines the location of SRAM as CC000.
DiskOnChip 2000 (DOC2000) is a Flash memory module. It contains an expansion
BIOS that allows Flash memory to emulate a disk drive when the corresponding
option is enabled in the BIOS Setup Advanced menu. If the system already
incorporates a C: drive (IDE), DOC2000 becomes the D: drive. When installed, the
DOC2000 module occupies memory address CC000-CFFFFh.

Serial and Parallel Ports
PC/AT peripherals include two high-speed, RS-232C, 16550-compatible serial ports
and one bi-directional Centronics-compatible parallel port.
UART1 (COM1) accepts an RS-232 or a RS-485 connection (you can only use one
connection at a time). UART2 (COM2) can be used for one of the following three
options:
•RS-232 out the 25-pin DB connector
•Touch screen controller interface
•Infrared (IR) interface
Use the BIOS setup menus to configure the port as a serial or infrared port. You can
use this port as both a serial and IR interface by allowing software to control the
connection.
Note
You cannot use UART2 as a serial and IR port at the same time.
If the touch screen controller is jumpered to use UART2 as a serial device, the 25-
pin DB connector cannot be used to interface to a device. These lines are combined
internally.
Note
The BIOS setup menus for UART2 must be set to standard operation to
use the touch screen controller on UART2.
Keyboard Ports
The keyboard port is routed to two separate connectors. One is a PS/2 connector,
allowing the keyboard to be routed out the side of the unit; the other connector
allows the keyboard to be routed to the front of the unit.
A polyswitch protects the +5 V on the keyboard port. This device opens if the +5 V
is shorted to GND. Once you remove the shorting condition, the polyswitch allows
current flow to resume.
Note
You can only use one keyboard port at a time.

CHIP4e+ Manual
10
Mouse Port
The CHIP4e+ supports two mouse ports. The external mouse port is routed to the
PS/2 mouse connector; the internal mouse port is routed to the touch screen
controller. If touch screen drivers are loaded, the external mouse port is disabled.
Both the external port and the touch screen controller may be plugged in at the same
time. However, the driver loaded may impair the operation of one of the ports. If the
Microtouch mouse drivers are loaded, the external mouse port will use these drivers.
Note
When using the Xycom touchscreen controller (PIN 140554), the
CHIP4e+ will behave the same. If using a PS/2 mouse is desired, install
the Touch-Base touch driver in serial mode. In serial mode, the
controller will use a COM port and free the PS/2 mouse port. Please
follow the installation instructions on the Xycom documentation.
A polyswitch protects the +5 V on the mouse port. This device opens if the +5 V is
shorted to GND. Once you remove the shorting condition, the polyswitch allows
current flow to resume.
IR Interface
The IR interface, which uses UART2, is a half-duplex serial port capable of 115
Kbaud transfer rates. It also supports two transfer formats: IrDA and ASKIR. You
must load software to support communication between two devices.
Flat-panel Interfaces
The CHIP4e+ incorporates two flat-panel connectors. The STN connector interfaces
directly to STN flat panels. It provides a substrate voltage (VEE) of 34 volts, contrast
control, and frame rate modulation to allow 4096 colors to be displayed. The TFT
connector interfaces directly to TFT flat panels.
The flat-panel type is jumper selectable. Refer to Chapter 2 for jumper settings.
Floppy and Hard Drives
The CHIP4e+ can interface to a floppy drive via the external floppy connector. To
connect a floppy drive to the external connector after power up, you must specify the
floppy drive as a 1.44 Mbyte drive, and disable the floppy check option in the BIOS
setup menus. If this is not done, the system will generate a floppy drive error during
the Power On Self Test (POST).
The PCI-to-IDE interface supports one hard drive via the on-board IDE controller.
Caution
The total IDE cable length must not exceed 18 inches.
