    There are some restrictions when setting up devices on the EPC-30. Booting from an ATA card can only be accomplished using a ROM extension such as the PhoenixPICO PCMBOOT.BIN file. The ROM extension reads the Card Information Structure (CIS) from the PCMCIA card and reads the geometry of the card.

Transfer Mode This option selects the mode that the System BIOS uses to access the hard disk. The only available selection is: Standard (default) Note that autotyping may change this value depending on the transfer modes that the hard disk reports it supports.

  • Page 34: Memory Shadow Sub-Menu

    Getting Started Memory Shadow Sub-menu The term “shadowing” refers to the technique of copying BIOS extensions from ROM into DRAM and accessing them from DRAM. This allows the CPU to access the BIOS extensions much more quickly and generally increases system performance if many calls to the BIOS extensions are made.

  • Page 35: Boot Options Sub-Menu

    The Real-Time Clock and 82C42PE are normally used inside the R380EX. ProcessorEXPLR1 Overview The standard EPC-30 uses the 33 MHz Intel386 EX in a 132-pin PQFP package. The 386 EX is a fully static, 32-bit processor optimized for embedded applications. It features low power consumption, a 16-bit external data bus, a 26-bit external address bus, and a 32-bit programming architecture compatible with Intel386 processors.

  • Page 53: Table 3-1. Functional Unit Summary

    30 has only one SIMM socket. The second module is the soldered-down DRAM (1MB, 2MB or 4MB configuration). After power on reset, the BIOS will find and size memory present in the system. The EPC-30 does not support parity DRAM.
  • Page 54 The BIOS includes support for a set of three different displays. The most common types of displays that work with the EPC-30 board are Monochrome, Passive Color, and TFT Color. Refer to the next section in this chapter, as well as Appendix E, LCD Flat Panel Interface, for more information.
  • Page 55 Sharp LM64P89 (Monochrome), but others are expected. Check the RadiSys Web page for more information, or contact RadiSys Technical Support. No circuitry is included on the EPC-30 for LCD contrast or backlight control. Flash Disk Subsystem The EPC-30 implements a Resident Flash Array (RFA) as a fully bootable read/write flash file system.
  • Page 56 EPC-30 Hardware Reference The RFA access may be implemented through a 16K memory window in the processor’s address space. This is useful for real mode operating systems such as DOS. The processor’s CS6 is used in addressing the RFA along with additional address bits from an upper address register.

  • Page 57: Serial And Parallel Ports

    The floppy disk controller uses programmed I/O mode; DMA operation is not supported. This makes it incompatible with some operating systems that don’t use the BIOS for floppy support. The EPC-30 supports one or two 5.25" 360KB and 1.2MB as well as 3.5" 720KB, 1.44MB, and 2.88MB drives and media.
  • Page 58 EPC-30 Hardware Reference The COMA serial port is provided by the first UART in the Intel386 EX processor, and is located in the I/O address range 0x3F8-0x3FF. COMA serial port interrupts are signaled using the interrupt IRQ4 within the processor. Disabling this COMA port routes its IRQ4 signal to an external pin on the 386EX, which makes it available for the SMC COMB and COMC ports.

    A PC-compatible keyboard controller is provided as part of the R380EX. Connection to it is made with a 6-pin mini-DIN circular connector, the type used in PS/2 designs and in other RadiSys CPU designs. These signals are duplicated in a 10-pin shrouded stake pin header.

  • Page 63: Power Requirements

    For example, the 28F016SV is a smart-voltage chip that can use 5V or 12V. the 28F016SA requires 12V to program. The current consumption of the EPC-30 is 1.3 amps or less (1 amp typical) in 5V mode, using a 33MHz Intel386 EX C-step processor, with a base memory configuration of 4 MB, in an idle state (DOS prompt).

  • Page 64: Mechanical Specifications
