Main Logic Board Jumpers

Jumper pins allow you to set specific computer parameters. They are set by changing the pin location of jumper blocks.  Note that the square pin of each jumper block is pin 1. A jumper block is a small plastic-encased conductor (shorting plug) that slips over the pins.  To change a jumper setting, remove the jumper from its current location with your fingers.  Place the jumper over the two pins designated for the desired setting.  Press the jumper evenly onto the pins.  Be careful not to bend the pins

	CAUTION Do not touch any electronic component unless you are safely grounded.  Wear a grounded wrist strap or touch an exposed metal part of the system box chassis.  A static discharge from your fingers can result in permanent damage to electronic components.

Beep Codes

When POST finds an error and cannot display a message, the computer's speaker emits a series of beeps to indicate the error and places a value in I/O port 80h.  During POST, if the video configuration fails or if an external ROM module does not properly checksum, your computer beeps three times (one long beep followed by two short beeps).

The following list contains other fatal errors and their associated beep codes.  Each code represents the number of short beeps that are grouped together.  Fatal errors (errors that lock up your computer) are generally the result of a failed main logic board or some other add-on component (SIMM, BIOS, computer battery, etc.).  If you cannot resolve problems using the Problem Solving and Troubleshooting procedures, contact Digital for additional assistance.

Beep Code	Error  Message

Device Mapping

These Help topics list your computer's device mapping.

Your computer's memory and address locations are allocated at the factory to operate within a standard PC environment.  Your computers Plug and Play capabilities can also allocate memory and address locations based on the types of Plug and Play expansion boards you have installed.  However, due to the number of optional devices and/or non-Plug and Play expansion boards that are available, sometimes memory and address locations need to be changed.  For example, some non-Plug and Play network expansion boards require a specific memory location.  If that location is already allocated, a memory conflict results and the expansion board will not operate as expected.  Note that some memory, I/O and interrupt locations can be changed using the BIOS Setup utility.

	CAUTION Before changing any memory or address location, refer to the documentation supplied with the optional device, expansion board, or software application and make sure adequate information is available.  If not, contact the option or software manufacturer for further information.

Your computer runs the POST, and prompts you for a supervisor or user password if you have set one.


Supervisor and User Password

Your Venturis 560 computer has two password levels that you can set to prevent unauthorized access to your computer files or BIOS Setup utility.  The supervisor is the primary password level and must be set before selecting a user password.  If you set a supervisor password, you will be prompted to enter it prior to accessing the BIOS Setup utility or before your operating system boots.

Setting these passwords also affects your ability to access your computer´s diskette drives.  The Diskette Access security feature defaults to the Supervisor setting when you set a supervisor password.  Unless the supervisor password has been entered, you cannot use your computer´s diskette drive to copy, transfer or store information.

If you set a user password and set the Diskette Access feature to User, entering either the user or supervisor password will allow you to use your computer´s diskette drives normally.  Failing to enter a correct password will prevent you from accessing the diskette drives.

Perform the following steps to set a supervisor and user password:

1.	Reboot your computer.

2.	After the POST has successfully completed, press [F2] to access Setup.

The Setup main menu appears on the screen.

3.	Highlight the Security menu and then press [Enter].
