BIOS update
When should a BIOS update be carried out?
Fujitsu Siemens Computers makes new BIOS versions available to ensure compatibility to new
operating systems, new software or new hardware. In addition, new BIOS functions can also be
integrated.
A BIOS update should always also be carried out when a problem exists that cannot be solved with
new drivers or new software.
Where can I obtain BIOS updates?
The BIOS updates are available on the Internet at www.fujitsu-siemens.de/mainboards.
How does a BIOS update work?
You have two ways of doing this:
1. BIOS update under DOS with bootable BIOS update floppy disk - brief description
