I want to change some settings in BIOS - Computers & Internet

Depending on what make & model of computer you have, right after the first beep during boot-up you will need to hit the "DEL" key or a function key. Watch the screen closely during boot-up and you should see a message that says "Hit DEL during startup to access BIOS." Dell computers usually use the "F2" key. You may have to tap it a few times to get into the BIOS. BE CAREFUL when you change settings in the BIOS. You can make the computer stop working if you change the wrong settings.

If you changed the CMOS battery you in effect reset it. On boot up, go into the BIOS setup and check all settings. Even if you don't change any of the BIOS settings, save them as if you did and it will reboot. Should be OK then.

Warning: Incorrect settings may produce undesirable results. Please research thoroughly before making any changes.

You can set the jumper as follows:

Clearing the BIOS settings
CAUTION: Do not change any jumper setting while the computer is on. Damage to the motherboard can result.
This motherboard has jumpers to clear the Real Time Clock (RTC) RAM in CMOS.

Clearing CMOS

To clear CMOS, follow these steps:

1. Temporarily set jumper Clear CMOS (CLRTC) to pins 1-2.
2. Wait 5-10 seconds and then return the jumper to pins 2-3.

When you startup the PC you will need to enter BIOS setup to reset any custom BIOS settings.

Clearing the BIOS password

The BIOS password is used to protect BIOS settings from unwanted changes. If you have forgotten your password you may disable password checking.
To erase the BIOS password follow these steps:

1. Turn OFF the computer and unplug the power cord.
2. Locate the jumper labeled Clear P.W. The jumper is found at the lower right edge of the motherboard.
3. Move the jumper on jumper Clear P.W. to pins 1-2.
4. Plug the power cord and turn ON the computer.

Hold down the F10 key during the startup process and enter BIOS setup to change or clear the password.

After changing or clearing the BIOS passwords, remember to reset the jumper to pins 2-3.

I followed the suggestion of changing the BIOS configuration to the recovery mode, however one thing was missing - it required a startup disk and I didn't have one. I then changed the BIOS configuration to the config (pins 2 & 3) mode, booted up and went to the BIOS/CMOS setup and a new menu tab appeared called "maintenance". I went to the advance tab and selected USB configuration and, instead of a blank screen, there appeared a selection for USB support and it showed disabled. I changed the setting to enabled and three more lines of information regarding USB came up, but required not further changes. I went to F10 and saved and exited and I now have me USB capability back.
