NOTE:
Your System BIOS may need to be Upgraded to support your new USB/PS2 add-on card
features. This can be obtained from your dealer and upgraded as described at the end of this
manual in section A, BIOS update. If your system was purchased with the add-on card already
installed then no further BIOS update is necessary.
