    2 System Board Chip-Set Chip-Set The chip-set comprises two chips. These interface between the three main buses (the Processor-Local bus, the PCI bus and the ISA bus). • The Bridge chip (SiS5581) is a combined PL/PCI bridge and cache controller and main memory controller and PCI/ISA bridge and IDE controller and USB controller.
  • Page 19 Level-2 Cache Memory The Level-2 cache memory controller supports either write through or write back direct mapped pipelined burst static RAM. On the HP Net Vectra Controller PC, 256KB of write back cache memory is implemented as two 32K chips soldered on the system board.

    2 System Board Chip-Set arbitrary order, back-to-back burst reads keep to the 5-2-2-2,5-2-2-2 timing pattern. When the banks have been filled contiguously (bank A, then bank B, then bank C), back-to-back burst reads are improved to a 5-2-2-2,3-2-2-2 timing pattern. IDE Controller The PCI master/slave IDE controller, supporting four devices, two on each of two channels, is described on page 26.

  • Page 30 Chapters 4 and 5. Updating the System ROM The System ROM can be updated with the latest BIOS. This can be downloaded, as a compressed file, from the HP Electronic Services ). You must specify the model of the computer http://www.hp.com/go/vectrasupport since the utility which is supplied for a different model cannot be used with this one.
  • Page 31 Do not switch off the computer until the system BIOS update procedure has completed, successfully or not. To do so could cause irrecoverable damage to the ROM, thereby requiring the replacement of the system board. The control panel switches are automatically disabled to prevent accidental interruption of the flash programming process, but this, of course, does not protect against deliberate or inadvertent removal of the power cord, or other types of power failure, however caused.
