    Although it is not pin compatible with the Pentium, the Pentium Pro is backward code-compatible. Software written for previous HP Vectra models will run on the Pentium Pro-based HP Vectras. However, only 32-bit programs execute faster. 16-bit programs might even only execute at the...

  • Page 16: Cache Memory

    Many techniques have been adopted to accelerate the throughput of the instruction-pipeline of the Pentium Pro over that of the Pentium. Firstly, it is super-pipelined : the individual operations of the Pentium pipeline have been broken down into many sub-operations, leading to a much longer pipeline of smaller operations.

  • Page 17: Processor-Local Bus

    PROCESSOR-LOCAL BUS The Processor-Local bus of the HP Vectra XU 6/150 PC and HP Vectra VT 6/150 PC is 64 bits wide, and is clocked at 60 MHz. Although carrying 64-bits of data, it is in fact composed of 141 signals.

  • Page 18: Main Memory

    Error Correcting Code Operation The HP Vectra XU 6/xxx PC can tolerate as many as one faulty memory bit per 64-bit line of instruction or data words. The erroneous bit is corrected (automatically and transparently) by the hardware. The computer program continues to execute as if no error had occurred.

  • Page 19: Devices On The Pci Bus

    The HP Vectra XU 6/xxx PC and HP Vectra VT 6/xxx PC are supplied with 16 MB of main memory as standard. The banks can be filled in any order, up to a maximum capacity of 256 MB, but always in pairs of memory modules of the same capacity and same type (ECC or non-ECC).

  • Page 48 SCA05 Run Setup to view your configuration and correct any obvious errors. If this fails to correct the problem, ensure that your hardware (accessory boards, disk drives, switches, and jumpers) is configured correctly (refer to their manuals). In particular, check that the CONFG switch on the system board is set to Off. Make a written note of the configuration before closing the cover.
