IBM IntelliStation Type 6866: Hardware Maintenance Manual
Attention:
If an interruption occurs during a Flash/BIOS upgrade, the BIOS might be left in an unusable
state. The Boot Block switch enables you to restart the system and recover the BIOS.
To perform a Flash/BIOS recovery, use the following procedure.
1.
Power-off the computer and remove the cover and front bezel.
2.
Move the system board rocker switch 3 to the on position. Refer to "System board
layout" on page 17 or the label inside the computer for more information.
3.
Insert the upgrade diskette into the diskette drive.
4.
Power-on the computer. The IBM Logo will appear.
Note: Depending on the amount of memory installed, it may take up to a minute
for the Logo to appear.
5.
When the Flash Update Utility appears, select the country/keyboard, then press
Enter.
6.
If the computer serial number was previously recorded, the number is displayed
with an option to update it. Press Y to update the serial number.
7.
Type the 7-digit serial number of the computer you are servicing, then press
Enter.
8.
Follow the instructions on the screen to complete the flash (BIOS/VPD) update
procedure.
9.
When you are instructed to reboot the computer, power-off the computer and
move the rocker switch 3 to the normal (off) position. Then replace the cover and
power-on the computer.
Power management reduces the power consumption of certain components of the
computer such as the system power supply, processor, hard disk drives, and some
monitors. Advanced Power Management and Rapid Resume™ Manager are features
of some personal computers.
Being an ACPI BIOS system, the operating system is allowed to control the power
management features of the computer and the setting for Advanced Power
Management (APM) BIOS mode are ignored. Not all operating systems support ACPI
BIOS mode.
Energy-saving settings can be viewed and changed by using the Advanced Power
Management menu in the Configuration/Setup Utility program.
