This chapter gives information about the system BIOS and tells how to configure the system by changing the settings of the BIOS parameters.
When you receive the system, it will already have been configured by SGI. You do not need to run Setup when starting the computer unless you get a Run Setup message.
The Setup program loads configuration values into the battery-backed nonvolatile memory called
CMOS RAM. This memory area is not part of the system RAM.
 | Note: If you repeatedly receive Run Setup messages, the battery may be bad. In this case, the system cannot retain configuration values in CMOS. Ask a qualified technician for assistance.
|
Before you run Setup, make sure that you have saved all open files. The system reboots immediately after you exit Setup.
To enter Setup, simultaneously press the key combination Ctrl+Alt+Esc.
| Note: To enter Setup, you must press Ctrl+Alt+Esc while the system is booting. This key combination does not work at any other time.
|
The system supports two
Setup utility levels: Basic and Advanced.
If you are an advanced user, you may want to check the detailed configuration of your system. Detailed system configurations are contained in the Advanced Level. To view the Advanced Level, press F8 while viewing the main menu.
Press the up and down arrow keys to move around the Setup Utility screen.
Press the Page Up, Page Down keys to move to the next page or to return to the previous page if the Setup screen has more than one page available.
Use the left and right arrow keys to select the options if they are available.
Press Esc to return to the main menu.
| Note: The figures in this chapter show the Setup screens. A parameter with an asterisk (*) indicates that the parameter appears only when you are in the Advanced Level. These asterisks are only shown in the figures in this guide; they do not appear on-screen. Also, grayed items on the screens have fixed settings and are not user-configurable.

The Setup program has a number of security features to prevent unauthorized access to the system and its data. Figure 3-12 shows the screen that appears if you select
System Security from the Setup Utility screen.
The
supervisor password prevents unauthorized access to the BIOS utility.
| Note: The supervisor password should be modified only by trained service personnel, or by a system administrator.
|
Setting and Changing a PasswordTo set or change a password, follow these steps:
Make sure that jumper JP8 is set to 1-2 (bypass password). Changing the jumper setting requires that the chassis be opened. This task should therefore be performed only by trained service personnel, and is detailed in the SGI 1100 Server Maintenance and Upgrades Guide (007-4047-001).
| Note: You cannot enter the BIOS utility if a Setup password does not exist and jumper JP8 is set to 2-3 (password check enabled). By default, jumper JP8 is set to 1-2 (bypass password).
|
Enable the
Supervisor Password parameter in the System Security menu by pressing the left or right arrow keys. The Supervisor Password window shown in Figure 3-13 appears.
Type a password in the Enter Password field. The password may consist of as many as seven characters.
Press the Enter key. Retype your password in the Enter Password field to verify your first entry.
Highlight Set or Change Password and press the Enter key.
Press the Esc key to return to the System Security menu and then press the Esc key again to exit Setup. The Exit Setup screen, shown in Figure 3-14, appears.
Select Yes to save your settings and exit the Setup utility. Your password will be saved to CMOS.
For the password to take effect, jumper JP8 must be set to 2-3 (check password). Changing the jumper setting requires that the chassis be opened. This task should therefore be performed only by trained service personnel, and is detailed in the SGI 1100 Server Maintenance and Upgrades Guide (007-4047-001).
The next time you want to enter the BIOS utility, you must key in your supervisor password.
To remove your supervisor password, follow these steps:
Disable the
Supervisor Password parameter in the System Security menu by pressing the left or right arrow key to select None.
Press the Esc key to return to the System Security menu and then press the Esc key again to exit Setup. The Exit Setup screen, shown in Figure 3-15, appears.
Select Yes to save your settings and exit Setup. Your previous password will be removed from CMOS.
| Note: When removing the supervisor password, it is important that jumper JP8 ne set to 1-2 (bypass password). This is because you cannot access Setup if a supervisor password does not exist and jumper JP8 is set to 2-3 (check password). Changing the jumper setting should be performed only by trained service personnel.
|
Bypassing a Supervisor PasswordIf you forget your
supervisor password, the password security feature can be bypassed by changing the setting of jumper JP8 to 1-2 (bypass password). Changing the jumper setting requires that the chassis be opened. This task should therefore be performed only by trained service personnel, and is detailed in the SGI 1100 Server Maintenance and Upgrades Guide (007-4047-001).
The
User Password secures your system against unauthorized use. Once you set this password, you have to type it whenever you boot the system. To set this password, enter the Setup utility, select System Security, and then highlight the User Password parameter. See Figure 3-16, and follow the same procedure as for setting the “Supervisor Password”.
| Note: The user password should be modified only by trained service personnel, or by a system administrator.
|
| Note: Jumper JP8 must be set to 2-3 to enable the user password. Changing the jumper setting requires that the chassis be opened. This task should therefore be performed only by trained service personnel, and is detailed in the SGI 1100 Server Maintenance and Upgrades Guide (007-4047-001).

| Onboard LAN
| When you set the PCI IRQ setting parameter to Auto, this
parameter specifies the auto-assigned interrupt for the
onboard LAN. If you set the PCI IRQ setting parameter to
Manual, you need to specify the interrupt that you want
to assign for the onboard LAN installed in your system.
| User input
| USB host
controller
| Allows you to manually assign the interrupt for the USB
host controller when the PCI IRQ setting parameter is set
to Manual. This parameter is grayed and not
user-configurable when the PCI IRQ setting is set to Auto.
| User input
| PCI IRQ sharing
| Setting this parameter to Yes allows you to assign the
same IRQ to two different devices. To disable the feature,
select No.
Note: If no IRQs are available to assign for the remaining
device function, it is recommended that you enable this
parameter.
| Yes
No
| VGA palette
snoop
| This parameter permits you to use the palette snooping
feature if you installed more than one VGA card in the
system.
The VGA palette snoop function allows the control palette
register (CPR) to manage and update the VGA RAMDAC
(Digital Analog Converter, a color data storage) of each
VGA card installed in the system. The snooping process
lets the CPR send a signal to all the VGA cards so that they
can update their individual RAMDACs. The signal goes
through the cards continuously until all RAMDAC data
has been updated. This allows the display of multiple
images on the screen.
Note: Some VGA cards have required settings for this
feature. Check your VGA card manual before setting this
parameter.
| Disabled
Enabled
| Plug and play OS
| When this parameter is set to Yes, BIOS initializes only
PnP boot devices such as SCSI cards. When set to No,
BIOS initializes all PnP boot and non-boot devices such as
sound cards.
Note: Set this parameter to Yes only if you are using a
plug-and-play-aware operating system, such as Windows
2000.
| Yes
No
| Reset resource
assignments
| Set this parameter to Yes to avoid IRQ conflicts when
installing non-PnP or PnP ISA cards. This clears all
resource assignments and allows BIOS to reassign
resources to all installed PnP devices the next time the
system boots. After clearing the resource data, the
parameter resets to No.
| No
Yes

The CPU Frequency screen in Figure 3-23 displays your CPU's speed and bus frequency.
Table 3-14 describes the CPU Frequency parameters. Settings in boldface are the default and suggested parameter settings.
Table 3-14. CPU Frequency Parameters
Parameter
| Description
| Option
|
|---|
Bus frequency
| The bus frequency refers to the speed by which data
is transferred between internal computer
components and the CPU (sometimes called Front
Side Bus, or FSB). Clock speeds are expressed in
megahertz (MHz), with 1 MHz being equal to 1
million cycles per second. A fast bus allows data to be
transferred faster, which makes applications run
faster.
| Options
| CPU frequency
multiple
| This column shows the CPU core/bus ratio of your
system. This ratio determines the clock speed of the
CPU core as a multiple of the bus speed. System BIOS
automatically detects CPU frequency multiple.
| 3X, 3.5X, 4X, 4.5X,
5X, 5.5X, 6X, 6.5X,
7X, 7.5X, 8X
| Processor speed
| The processor speed is the bus frequency multiplied
by the CPU frequency multiple, and is set
automatically by BIOS. The faster the clock, the more
instructions the CPU can execute per second.
When two CPUs are installed, they will both run at
the same frequency.
|
| Single processor MP
table
| Enabling this parameter allows BIOS to create a
multiprocessor (MP) table for Windows NT use. In a
single-processor system running Windows NT, you
may disable this parameter to enhance system
performance. If you install another CPU for a dual
system, enable this parameter and then re-install
Windows NT.
In cases when this parameter is enabled before
installing Windows NT in a single-processor system,
you may upgrade to a multiprocessor system without
reinstalling Windows NT.
| Enabled
Disabled
| MP table version
| Version number of the MP table.

Use this option to load the default settings for the optimized system configuration. When you load the default settings, some of the parameters are grayed-out with their fixed settings. These grayed parameters are not user-configurable.
The dialog box in Figure 3-24 appears when you select
Load Default Settings from the main menu.
Select Yes to load the default settings.
Select No to ignore the message and return to the BIOS utility.
Use this option to disregard your changes to the BIOS and reload your previous settings. The dialog box in Figure 3-25 appears when you select
Abort Settings Change from the main menu.
Select Yes to disregard your changes and reload your previous settings. After reload, the main menu appears on the screen.
Select No to ignore the message and return to the BIOS utility.
Examine the system configuration values. When you are satisfied that all the values are correct, write them down. Store the recorded values in a safe place. In the future, if the battery loses power or the CMOS chip is damaged, you will know what values to enter when you rerun Setup.
Press the Esc key to
exit Setup. The dialog box shown in Figure 3-26 appears.
Use the arrow keys to select your response. Press the Enter key.
If you made any changes to the Setup utility, the dialog box shown in Figure 3-27 is displayed.
Use the arrow keys to select your response. Select Yes to save the changes in CMOS. Select No to retain the previous configuration values. Press the Enter key to exit.
