    Introduction This manual is for integrators and programmers of systems based on the Ampro Little Board/P5x, a full-featured CPU module conforming to the EBX 1.1 technical specification. It contains technical information about hardware requirements, interconnection, and software configuration. Technical Support Ampro technical support for this product is available from 8:00 AM to 5:00 PM, Pacific Time, Monday through Friday.

  • Page 7: Introduction

    General Description The Little Board/P5x is a high integration, high-performance Pentium-based PC/AT-compatible system that conforms to the EBX V.1.1 specification. This rugged and high quality single-board system contains all the component subsystems of a PC/AT PCI motherboard plus the equivalent of up to six expansion boards.
  • Page 8 The Pentium CPU has its standard on-chip cache memory (typically 16K). In addition, a 512K byte synchronous-burst secondary cache is provided to increase performance. The board uses a single DIMM memory module for main DRAM memory, and supports from 16M bytes to 256M bytes in a 64-bit configuration.
  • Page 9 Little Board/P5x Technical Manual be stacked directly on top of the Little Board/P5x using its PC/104-Plus expansion bus interface as a rugged and reliable interconnect. The Little Board/P5x module’s on-board EIDE, video interfaces, and optional SCSI interface are internally connected to its PCI bus. In addition, you can attach PCI peripherals to the board’s stackable PCI bus expansion connector in much the same way PC/104 modules are stacked on the PC/104 connectors.
  • Page 10 specification and the ATAPI Specification. The Ampro Extended BIOS supports hard drives greater than 528M bytes through Logical Block Addressing (LBA). The Compact Flash interface is implemented as an IDE drive. If it is installed, it takes the position of one of the drives of the primary IDE interface (settable as a master or slave drive). PCI UltraSCSI Interface An PCI UltraSCSI controller subsystem is available by special order.

Battery drain for the clock is less than 0.4 uA. This battery will support the clock for more than 10 years of normal usage.

  • Page 34: Rom-Bios Installation Of The Serial Ports

    ROM-BIOS Installation of the Serial Ports Normally, the ROM BIOS supports Serial 1 as the DOS COM1 device, Serial 2 as the DOS COM2 device, and so on. If you disable a serial port, and there is no substitute serial port in the system, then the ROM-BIOS assigns the COMn designations in sequence as it finds the serial ports, starting from the primary serial port and searching to the last one, Serial 4.
