AR-B9622 User’s Guide 2. SYSTEM CONTROLLER This chapter describes the major structure of the AR-B9622 CPU board. The following topics are covered: ! ! ! ! ! ! Microprocessor DMA Controller Keyboard Controller Interrupt Controller Serial Port Parallel Port 2.1 MICROPROCESSOR The AR-B9622 uses the ALI M6117 CPU; it is designed to perform systems like Intel’s 386SX system with deep green features. The 386SX core is the same as M1386SX of Acer Labs. Inc.
AR-B9622 User’s Guide 2.3 KEYBOARD CONTROLLER The 8042 processor is programmed to support the keyboard serial interface. The keyboard controller receives serial data from the keyboard, checks its parity, translates scan codes, and presents it to the system as a byte data in its output buffer. The controller can interrupt the system when data is placed in its output buffer, or wait for the system to poll its status register to determine when data is available.

Overview System Setting 3.1 OVERVIEW The AR-B9622 is an all-in-one, half-size, 386SX CPU board. This section provides hardware jumper settings, the connectors’ locations, and the pin assignment. CAUTION: The CPU board doesn’t support the SIMM-type DRAM.
AR-B9622 User’s Guide 3.2 SYSTEM SETTINGS Jumper pins allow you to set specific system parameters. Set them by changing the pin location of jumper blocks. (A jumper block is a small plastic-encased conductor [shorting plug] that slips over the pins.) To change a jumper setting, remove the jumper from its current location with your fingers or small needle-nosed pliers. Place the jumper over the two pins designated for the desired setting. Press the jumper evenly onto the pins.
