Bios Settings - Hitachi CE50-10 Instruction Manual

7. Maintaining the CE50-10
7.1 BIOS settings
BIOS containing system configuration information is stored in battery-backed-up SRAM (CMOS) and ROM. If you
change the system configuration, BIOS settings might need to be changed.
Note:
At the time of product shipment, the BIOS settings are optimized for the system configuration.
Changing the BIOS settings might cause unstable operation or might prevent the system from starting normally.
Do not change the settings of the items for which change is prohibited in Table 7-2 BIOS setup menu list.
Note that the BIOS might be updated during repair work. In that case, the BIOS password and other settings will
be initialized.
