Controllers • System Unit with Socket 7 (ZIF)
This BIOS mode can be activated by making the following jumper settings:
If the IPC has been switched to recovery mode, a special BIOS in the CMOS memory boot block
is then used. This BIOS is permanently written by the manufacturer (Award) to the CMOS
memory (cannot be modified) and initializes only those system components which are absolutely
necessary for the execution of the upgrade.
When starting up in recovery mode, the operating system must be started from a bootable
diskette, because no mass memory devices are initialized by BIOS.
After the IPC has been started in recovery mode, another fully functioning BIOS must be written
using BIOS Upgrade Utilities (see the "BIOS Upgrade" section ). After a successful upgrade, the
IPC must be switched off and the recovery jumper returned to the standard setting. BIOS then
boots again properly.

The user jumper is not required for setting system functions. It can be utilized by the user and
