Replacing The Microprocessor - HP Vectra VE5 2 Supplementary Manual

NOTE
Plug and Play
The HP Vectra VE 5/xx series 2 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).
All PCI accessory boards are Plug and Play, although not all ISA boards are. Check the
accessory board's documentation if you are unsure.
Non-Plug and Play in Windows 3.11
To install an ISA accessory board which is not Plug and Play in Windows 3.11, start the ICU
program to declare the resources used by the board.
To run the ICU:
1 Choose the Plug and Play facility in the Windows Program Manager.
2 Click on the ICU icon to launch the ISA Configuration Utility and configure system
resources for the accessory board.
The ICU is preloaded with configuration details for many non-Plug and Play accessory boards.
If your accessory board is not listed by the ICU, there are two ways you can configure the
accessory board:
3 Some non-Plug and Play accessory boards are supplied with a configuration file which
can be used by the ICU to determine which resources are required by the board. When
prompted by the ICU, insert the diskette containing the configuration file.
4 If there is no configuration file for your accessory board, you will need to enter the
configuration details manually when prompted by the ICU. Refer to the documentation
supplied with the accessory board for information about the resources the board requires.
Non-Plug and Play in Windows 95
To install an ISA accessory board which is not Plug and Play in Windows 95, run the Add New
Hardware wizard to configure the accessory. The settings selected by Windows 95 may be
different from those recommended by the board's manufacturer. Should this be the case, it
might be necessary to alter the board's jumpers.
Refer to the documentation supplied with Windows 95 for further details.

REPLACING THE MICROPROCESSOR

The system board has a ZIF - Zero Insertion Force - "universal" socket to allow the
microprocessor to be easily changed. Each microprocessor has a Voltage Regulator Module
(VRM) which must be installed with the microprocessor.
The 75, 100 and 133 MHz Pentium processors, as mounted in the various models, use the
shortening block VRM 5063-7939.
PCI slots have a 5V supply only, and not a 3.3V
supply.
