Static electricity is a constant danger to computer systems. The charge that can build up in your body may be more than sufficient to damage integrated circuits on any PC board. Therefore, it is very important to observe basic precautions whenever you use or handle computer components. Although areas with humid climates are much less prone to static build-up, it is always best to safeguard against accidents that may result in expensive repairs. The following measures should be sufficient to protect your equipment from static discharge: • Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a grounded wrist strap). • When unpacking and handling the board or other system components, place all materials on an anti-static surface. • Be careful not to touch the components on the board, especially the “golden finger” connectors on the bottom of the board. 3 AR-B1423 User’s Guide 1.

The effect is the use of floppy in WIN95 would be unable. The bug can be revised in CPU with C5 as a version. But according to ST as the original manufacturer, C5 just can normally be produced at least in October. The bug still exists so it is better to use the C4. Therefore, we decided to adopt no support as our temporary strategy. In AR-B1423B section, we have to install WIN 95, and then set up the Floppy driver as the additional step in order to drive the AR-B1423B Floppy device properly. The AR-B1423A& AR-B1423B can access from 64MB to 128MB of external memory. 5 AR-B1423 User’s Guide 2. SYSTEM CONTROLLER This chapter describes the main structure of the AR-B1423 CPU board.

The figure below describes a complete implementation of the IRQ [15:0] time multiplexing. When an interrupts line is used internally, the corresponding input can be grounded. In most of the embedded designs, only few interrupts lines are necessary and the glue logic can be simplified. Typical IRQ multiplexing When the interface is integrated into the STPC, the corresponding interrupt line can be grounded as it is connected internally. For example, if the integrated IDE controller is activated, the IRQ [14] and IRQ [15] inputs can be grounded. 9 AR-B1423 User’s Guide 2.6 DMA CONTROLLER � DMA channel � 2X8237/AT compatible 7-channel DMA controller integrated into the STPC. � 2X8259/AT compatible interrupt Controller integrated into the STPC. 16 interrupt inputs – ISA and PCI. � Three 8254 compatible Timer/Counters integrated into the STPC. � Co-processor error support logic. The figure below describes a complete implementation of the external glue logic for DMA Request time- multiplexing and DMA Acknowledge demultiplexing. Like for the interrupt lines, this logic can be simplified when only few DMA channels are used in the application. This glue logic is not needed in Local bus mode and it does not support DMA transfers. Typical DMA multiplexing and demultiplexing 10 AR-B1423 User’s Guide 2.7 TIMER / COUNTERS � System Activity Detection. � Three power down timers. � Doze timer for detecting lack of system activity for short durations. � Stand-by timer for detecting lack of system activity for medium durations. � Suspend timer for detecting lack of system activity for long durations. � Housekeeping activity detection. � Housekeeping timer to cope with short bursts of housekeeping activity while dozing or in stand-by state. 2.8 IDE CONROLLER � Supports PIO. � Transfer Rates to 22 Mbytes/sec. � Supports up to 2 IDE devices. � Concurrent channel operation (PIO modes) – 4 x 32-Bit Buffer FIFOs per channel. � Support for PIO mode 3 & 4. � Individual drive timing for all two IDE devices. � Supports both legacy & native IDE modes. � Supports hard drive larger than 528MB. � Support for CD-ROM and tape peripherals. � Backward compatibility with IDE (ATA-1). � Drivers for Windows and other Operating Systems. 2.9 OPTIONAL 16-BIT LOCAL BUS INTERFACE � Multiplexed with ISA/DMA interface. � Low latency asynchronous bus. � 22-bit address bus. � 16-bit data bus with word steering capability. � Programmable timing (Host clock granularity). � Two Programmable Flash Chip Select. � Four Programmable I/O Chip Select. � Supports 32-bit Flash burst. � Two-level hardware key protection for Flash boot block protection. � Supports two banks of 16MB flash devices with boot block shadowed to 0x000F0000. 2.10 ISA MASTER / SLAVE � Generates the ISA clock from either 14.318 MHz oscillator clock or PCI clock. � Supports programmable extra wait state for ISA cycles. � Supports I/O recovery time for back-to-back I/O cycles. � Fast Gate A20 and Fast reset. � Supports this single ROM that C, D, or E.

This section provides the hardware’s jumper settings, the connectors’ locations, and the pin assignments. External System Location 3.2 SYSTEM SETTING 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 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. Be careful not to bend the pins. CAUTION: Do not touch any electronic components unless you are safely grounded. Wear a grounded wrist strap or touch an exposed metal part of the system unit chassis. The static discharges from your fingers can permanently damage electronic components. 13 AR-B1423 User’s Guide 3.2.1 PC/104 Connector (1) 64 Pin PC/104 Connector Bus A & B (PC1) 2 64 1 63 64 Pin PC/104 Connector PIN NO SIGNAL PIN NO SIGNAL 1 –IOCHCK 2 GND 3 SD7 4 RSTDRV 5 SD6 6 VCC 7 SD5 8 IRQ9 9 SD4 10 Not Used 11 SD3 12 DREQ2 13 SD2 14 Not Used 15 SD1 16 –ZEROWS 17 SD0 18 (+12V) 19 IOCHRDY 20 GND 21 AEN 22 –SMEMW 23 SA19 24 –SMEMR 25 SA18 26 –IOW 27 SA17 28 –IOR 29 SA16 30 –DACK3 31 SA15 32 DREQ3 33 SA14 34 –DACK1 35 SA13 36 DREQ1 37 SA12 38 –REFRESH 39 SA11 40 SYSCLK 41 SA10 42 IRQ7 43 SA9 44 IRQ6 45 SA8 46 IRQ5 47 SA7 48 IRQ4 49 SA6 50 IRQ3 51 SA5 52 –DACK2 53 SA4 54 TC 55 SA3 56 BALE 57 SA2 58 VCC 59 SA1 60 OSC 61 SA0 62 GND 63 GND 64 GND 14 AR-B1423 User’s Guide (2) 40 Pin PC/104 Connector Bus C & D (PC1) 1 39 2 40 40 Pin PC/104 Connector PIN NO SIGNAL PIN NO SIGNAL 1 GND 2 GND 3 –SBHE 4 –MEMCS16 5 LA23 6 –IOCS16 7 LA22 8 IRQ10 9 LA21 10 IRQ11 11 LA20 12 IRQ12 13 LA19 14 IRQ15 15 LA18 16 IRQ14 17 LA17 18 –DACK0 19 –MEMR 20 DREQ0 21 –MEMW 22 –DACK5 23 SD8 24 DREQ5 25 SD9 26 –DACK6 27 SD10 28 DREQ6 29 SD11 30 –DACK7 31 SD12 32 DREQ7 33 SD13 34 VCC 35 SD14 36 –RMASTER 37 SD15 38 GND 39 Not Used 40 GND 3.2.2 FDD Port Connector (FDD1) The AR-B1423 provides a 34-pin header type connector for supporting up to two floppy disk drives.
