    The EUROCOM 148 is delivered with an EMBEDDED BIOS from GENERAL SOFTWARE. The BIOS includes a setup menu to configure basic settings. ELTEC ships the EUROCOM 148 with optimized BIOS settings. If desired, most of the BIOS settings can be changed (some settings are hardwired). Also if the battery for the CMOS RAM is weak, the RAM may loose its contents making a new setting of the setup necessary.

  • Page 46: Pci/Vmebus, How Does It Work

    VMEbus environment. Nevertheless, before VMEbus can be used, the ELTEC VME/PCI-Bridge chip has to be set up to fit into the desired application. The chip itself is complex, but the programming is easier as you might expect. This chapter contains a short description how to handle the ELTEC VME/PCI-Bridge for the mainly used VMEbus features.
  • Page 47 PCI addresses generated by the CPU (or other PCI initiators) will be responded by the ELTEC VME/PCI-Bridge in this window, if the address is equal to or higher than the address given in the base register and lower than the value given in the bound register.

  • Page 48: Vmebus Master Access

  • Page 49 1.5.5.3. Using RMW with VMEbus Master Access The ELTEC VME/PCI-Bridge can generate read-modify-write cycles (RMW) on VMEbus if it is a VMEbus master. Once a VMEbus master window has been set up, this window can be used to generate RMWs on the VMEbus.
  • Page 50 ELTEC VME/PCI-Bridge will respond as a slave. The VMEbus address is added to the translation offset and the resulting address is placed on PCI. Follow the steps to set up the ELTEC VME/PCI-Bridge as a VMEbus slave.

  • Page 51: Vmebus Slave Access

    Chapter 1. Hardware part Figure 1.17. VMEbus Slave Access...
  • Page 52 VMEbus interrupt by setting the SW_INT bit within the VINT_EN register. After the ELTEC VME/PCI-Bridge has caused an interrupt on the VMEbus an IACK cycle will take place. The handler of the interrupted device will read the interrupt vector. The interrupt vector which is delivered by the ELTEC VME/PCI-Bridge has to be stored in the interrupt status/ID out register STATID (offset 0x320) prior to the first interrupt.
  • Page 53 ELTEC VME/PCI-Bridge. Typically a PCI device has not more than one interrupt output, it never functions as an input! It is up to the user to run the local interrupt mechanism of the ELTEC VME/PCI-Bridge following the PCI specification or not. The PCI interrupts are routed via the local interrupt controller to ISA interrupts.
  • Page 54 IACK daisy chain driver and a bus timer. The ELTEC VME/PCI-Bridge is automatically the system controller if the EUROCOM 148 is installed in the first slot of the bus. Software can check if the system controller function is enabled via reading the SYSCON bit in the miscellaneous control register MISC_CTL (offset 0x404).
  • Page 55 Chapter 1. Hardware part 1.5.5.8.1.3. Changed behavior • PCI target images have to be mapped inside the PCI resource 1. The Universe II has used unused address space to map his PCI target images. This disagrees to the PCI specification because this behavior can cause address violations. The Galaxy uses an additional memory mapped resource which can be set to 128 MByte, 256 Mbyte, 512 Mbyte or 1 GByte.

    Pending write cycles from the CPU to VMEbus will not release the PCI bus while an external VMEbus master tries to access the local memory of the EUROCOM 148. This will result either in a bus timeout error on VMEbus or if the BTO counter is disabled in a complete system deadlock. Enabling the...
