SECTION 3 - SETUP
The IRV-686 SBC uses the latest AWARD Plug-n-Play BIOS which contains an internal Setup Utility
for configuring the system. The BIOS includes a graphical user interface, and a new system
configuration utility, as well as all the features of the standard BIOS. The system configuration
settings are stored in the on-board CMOS memory which is backed up by a Lithium battery. Should
your CMOS become corrupted, i.e. loss of battery power or accidentally clobbered, strange errors
may occur while attempting to run your programs. A jumper at JP1 has been provided to force the
BIOS to use its internal default SETUP values. This is accomplished by first removing power from
the IRV-686 and momentarily interrupting the battery power to the system controller chip. To
interrupt the battery power, remove the shunt from pins 1 & 2 and momentarily connect it to pins 2
& 3 (the "Clear CMOS" position). After waiting a few seconds, return the shunt back to its original
position. Refer to Appendix E for the jumper location.
WARNING: DO NOT apply power to the IRV-686 with the shunt in the clear CMOS position --
serious damage will result.
The Setup Utility can be invoked by first causing a cold boot (reset) or a warm boot (Cntrl Alt
Del) and pressing the Del key when instructed. This will cause the memory diagnostics to be
aborted and the Setup Utility to display the MAIN SETUP MENU. Using the
→→↑↑↓↓←← cursor keys,
move the highlighted bar to the option you wish to modify and then press Enter to select it. When
in the MAIN SETUP MENU, the F2 key is used to select the colors used in the setup screens, and the
F10 key is used to save the changes before exiting the Setup Utility. The Esc key may be used to exit
the Setup Utility without saving the changes. The PgUp and PgDn keys are used to scroll through
the selections for a given setting. PgUp is also used to decrease the setting and PgDn to increase the
setting. In addition, you may also enter the setup utility directly by pressing the Cntrl Alt Esc
simultaneously.
After making the desired selections from the various setup menus, you can save your selections by
pressing the F10 key or by selecting the appropriate selection from the MAIN SETUP MENU.
Notes:
1. The user should be aware that improper selection of certain values in the CHIPSET, POWER
MANAGEMENT, and PNP/PCI selections may cause unpredictable results. If this occurs select
the LOAD BIOS DEFAULTS from the MAIN SETUP MENU and then press the F10 to save and
exit.
