advising an upgrade appears. In this situation the Security Card
cannot be used without upgrading the BIOS – the security system
will not allow the computer to boot until the BIOS is upgraded.
BIOS upgrades are normally performed by a service engineer. Ask
your supplier or authorized maintainer for assistance. If you need to
use the computer in the meantime, simply remove the Security Card.
Entering the System Identification Number (SIN)
Every Apricot LS Security Card has a unique System
Identification Number or SIN programmed into it at the factory.
When installing a Security Card
After installing the Security Card in an Apricot computer with LOC
Technology BIOS support, you are prompted to type in the Security
Card’s SIN when turning on the computer for the first time.
When replacing a Security Card
If you replace one Security Card with another you are required to
supply the SINs of both old and new cards. If the new card had
already been programmed with a security configuration, that
configuration is erased automatically when you enter its SIN.
Erasing the security configuration
In exceptional circumstances it may be necessary to erase the
Security Card’s security configuration and start again.
To erase the security configuration:
1. Turn off the computer and unplug all power cords.
2. Take suitable anti-static precautions and remove the system
unit cover.
If you are unfamiliar with the recommended anti-static
precautions or the process of removing the system unit cover,
refer to the computer’s Owner’s Handbook.
