System Board Switches

 

Five of the system board switches (whose location is shown on page 20) set

 

the working frequencies for the computer, as summarized on page 31. The

 

others set the configuration for the computer, as summarized in the table on

 

the next page.

Functions of the System Board Switches

 

 

 

1-4,7-8

 

Bus frequencies (see the table on page 31)

 

 

 

 

 

Password:

5

 

Open = enabled (default)

 

 

Closed = disabled / clear User and Administrator passwords

 

 

 

 

 

Clear CMOS:

6

 

Open = normal (default)

 

 

Closed = clear CMOS (to reload the Setup program defaults)

 

 

 

 

 

Keyboard space-bar power-on:

9

 

Open = disabled

 

 

Closed = enabled (default)

 

 

 

 

 

Product identification:

10

 

Open = normal operation (default)

 

 

Closed = clear the product identification field in the CMOS memory

 

 

 

 

By setting switch SW6 in the Closed position, not only is the configuration

 

data cleared (in the CMOS memory and the Serial EEPROM), but also all the

 

Plug-and-Play data that had been saved in the Serial EEPROM. However,

 

the serial number, the tattooing string, the date and the time are each

 

retained.

 

By setting switch SW9 in the Closed position, the Power-On Space-Bar

 

function is enabled. Note, though, that it must also be enabled in the

 

Power-OnSpace-Barfield of the Power Menu in the Setup program.

 

Turning the computer on, with switch SW10 in the Closed position, clears

 

the product identification field in the BIOS, and causes the computer to

 

prompt for the new information. By identifying the product correctly (after

 

replacing a defective system board by a new one), the BIOS is able to tailor

 

itself for the particular product, and to enable the appropriate features.
