PRINCIPAL COMPONENTS AND FEATURES The system board, as depicted on the next page, contains the following components: Processor Socket The microprocessor is packaged in a pin-grid-array (PGA), which is seated on the system board in a zero-insertion-force (ZIF) socket .
  • Page 13 Main Memory Sockets There are six main memory module sockets , arranged in three banks (A to C), allowing installation up to 128 MB DRAM. One bank is already occupied by the pair of memory modules that contain the 8 or 16 MB of memory that is fitted as standard (depending on the model of the PC).

  • Page 14: The Backplane

    It shows two accessory slots on the PCI bus, two on the ISA bus, and one that lies on either bus. Thus there are three PCI accessory sockets, and three ISA bus accessory sockets. The lowest ISA socket can only accommodate an HP proprietary ISA accessory board.

    The L2 cache memory, when fitted, also has a 32-byte line size. It is controlled by the PL/PCI bridge chip (see page 10) in the system board chip-set. A single HP cache memory module consists of 256 KB of direct mapped, synchronous or asynchronous, static random access memory (SRAM).

  • Page 18: Devices On The Pci Bus

    Upgrades The Setup program automatically detects which memory module capacity, and speed is installed in each bank. Individual pages of memory can be configured as cacheable or non- cacheable by software or hardware. They can also be enabled and disabled by hardware or software.

    Further details, and the tables of supported video resolutions, can be found in the next chapter. INTEGRATED DRIVE ELECTRONICS (IDE) The IDE controller is implemented as part of the PCI/ISA bridge chip. It supports Enhanced IDE (EIDE) and Standard IDE (Bus Master IDE). To use the Enhanced IDE features, though, hard disk drives must be compliant with Enhanced IDE.

    (IRQs, DMAs, memory ranges, and I/O addresses) are used by the system-based components. The HP Vectra XM 5/xx series 4 PC has a “PnP level 1.0A” BIOS and meets the “Windows 95 Required” level for Plug and Play. Accessory boards which are Plug and Play are automatically configured by the BIOS (Windows 3.11) or by the operating system (Windows 95).

    The POST performs the tests in the order described in the following table. The POST starts by displaying a graphic screen with the initial HP “Vectra” logo. If the POST detects an error, the error message is displayed inside a view system errors screen, in which the error message utility (EMU) not only displays the error diagnosis, but the suggestions for corrective action.

    When the PC is switched on or reset, a power-on hardware test is performed. If an error occurs, an error message is displayed. HP’s new style BIOS does not display POST error codes (such as 910B) which existed in the BIOS of previous HP Vectra PCs.
