Configuring startup devices

When your computer is turned on, it looks for an operating system. The order in
which it searches devices for the operating system is the startup sequence. After
adding new devices to the computer, you might want to change the startup
sequence. You can use the Configuration/Setup Utility program to configure
startup devices. For more information, see Access IBM.

Erasing a lost or forgotten password (clearing CMOS)

This section applies to lost or forgotten passwords that are not protected by
Enhanced Security. For information about lost or forgotten passwords that are
protected by Enhanced Security, see "Appendix A. Using Enhanced Security" on
page 71.
To erase a forgotten password:
If you install a PCI adapter that supports an automatic power-on function, you
can enable the power-on function through the Configuration/Setup Utility
program. When the automatic power-on function is enabled, the computer can
be started remotely through a network or through the telephone lines,
depending on the type of adapter installed. An example of this type of adapter
is a modem that supports the ring-detection function. To enable the PCI Wakeup
function:
1. Start the Configuration/Setup Utility program (see Access IBM).
2. From the Configuration/Setup Utility program menu, select Power
Managementand press Enter.
3. Select Automatic Power On and press Enter.
4. In the PCI Wakeup line or the PCI MODEM Ring detect line (depending on
the type of device), use the arrow keys to set the setting to Enabled. Then, in
the corresponding Startup Sequence line, select either Primary (for primary
power-on sequence) or Automatic (for automatic power-on sequence). For an
explanation of the power-on sequence, see Access IBM.
5. Press Esc until you return to the Configuration/Setup Utility program menu.
6. Before you exit from the program, select Save Settings from the
Configuration/SetupUtility program menu and press Enter.
7. To exit from the Configuration/Setup Utility program, press Esc and follow
the instructions on the screen.
1. Turn off the computer and all attached devices.
2. Unplug the power cord.
3. Remove the cover. See "Removing the cover" on page 21 (desktop model),
"Removing the cover" on page 35 (minitower model), or "Removing the
cover" on page 53 (microtower model).
4. Refer to the system board label inside the computer to locate the clear CMOS
jumper on the system board.
5. Set the jumper from the standard position (pins 1 and 2) to pins 2 and 3.
6. Replace the cover and plug in the power cord. See "Replacing the cover and
connecting the cables" on page 32 (desktop model), "Replacing the cover and
connecting the cables" on page 51 (minitower model), or "Replacing the cover
and connecting the cables" on page 65 (microtower model).
