Cimos setup

If you're trying to change the clock, speed, or other settings and don't have the option available, it's because the motherboard doesn't support it. If you believe it should be supported, you may need a BIOS update. If changes you made appear to revert to default settings or the date and time setting in the BIOS keeps falling behind, you may need to replace the CMOS battery.

If any changes are made, you need to save those changes, which is usually done by pressing the F10 key on the keyboard. If F10 doesn't work, look at the bottom or top of the screen for the key that's used to save the settings. Unlike the computers of today, older computers before had numerous methods of entering the BIOS setup.

Below is a listing of key sequences to press as the computer is booting to enter the BIOS setup. If your Acer computer cannot boot or you want to restore the BIOS to its original settings, press and hold the F10 as you turn on the computer.

While continuing to hold the F10 , two beeps should be heard indicating that the settings are restored. Early , , and computers required a floppy disk to enter the BIOS setup. Because these diskettes are unique to your computer manufacturer, you must obtain the diskettes from them.

See the computer manufacturers list for contact information. Finally, if none of the above suggestions allow access to your CMOS setup, try generating a stuck key error, which gives an option to enter the CMOS setup.
