Reset default bios P4M800PRO

There is a lot of info on Fixya website about this. Just Google search:
Xpsp sp3 qfe 130704 0421 I did not read through the responses, but if your problem is not among those addressed, try booting to safe mode, and see if you can correct the problem (F8 during post sequence). If you are unable to restore to an earlier Windows configuration that works (or if it still will not boot), I would suggest you reset bios to default (Press Del upon post, or F1 on some machines). Select default settings (listed differently for different bios configs), and follow directions (usually press F10 to save). I hope this helps you resolve your problem. Your problem could be OS (sometimes repaired by the first method), or bios config (repaired by the second method).

1.
Click "Start | All Programs | TOSHIBA | Utilities | HWSetup" to open the laptop's original equipment manufacturer, or OEM, system configuration software.


2.
Click "General," then "Default" to reset the BIOS settings to their original state.

3.
Click "Apply," then "OK."

Restore BIOS Settings at Startup
1.
Restart or power on the Toshiba. Quickly press "F2" to access the boot screen. If you miss the boot screen and the computer continues to start Windows, shut down and try again.

2.
Press "F9" to load the BIOS setup defaults on the laptop. Use the directional pad to select "Yes" and then press "Enter."

3.
Go to the "Exit" tab. Select "Exit Saving Changes." Choose "Yes." Press "Enter" to quit.

some motherboards do have a pin/plug which can remove passworcs i would need to name and model number of the board to find the specifications Power off the computer and make sure that it is unplugged

Open up your computer case. You need physical access to the motherboard to complete this procedure

Find a circular, (mostly) silver metallic object on the motherboard. This is the CMOS battery

CAREFULLY remove the CMOS battery, avoid touching it with your fingers, and leave it out for about 120 seconds. This will flush the CMOS memory which stores the BIOS password and all other configuration. (See Warnings)

Set the battery back into place and power on the computer

The computer should then warn you that the CMOS configuration could not be found. You can either reconfigure it yourself or restore defaults. Restoring the default configuration should be fine.

You will notice that the BIOS password has been cleared and you can boot without it. You may reset the BIOS password to something else by going into the BIOS configuration and setting a new User Password (The Supervisor Password controls access to the BIOS, NOT the computer!)

Hope this helps

Hi dianneruss56,
I see you are asking about the correct configuration of you system BIOS.
To set the BIOS on your Machine to what it was before you will just have to set it back to defaults.
Once in the BIOS page press F9 once the it should ask you if you want to go ahead and set it to defaults just click yes then press F10 to save and exit this should reset everything to defaults setting for you in your BIOS.
I hope this helps.

There are two ways you can restore the CMOS/BIOS back to the factory default.
First, turn off the laptop and remove the BIOS battery for 15 mins.
Insert the BIOS battery back again and go into the BIOS configuration to set the Date and Time etc.
Second, go into the BIOS configuration press the f1 or F2 or F10 key (not sure which key for your model DELL). When you get into the BIOS then there is a setting to restore the BIOS to the default, then save setting and exit.

You can reset the BIOS back to the default setting by going into the BIOS configuration and there should be a setting "Load default settings" then save and exit.
The other way to reset the BIOS is to remove the BIOS battery, wait 1/2 hour, insert the battery, then go into the BIOS configuration and set the Date & Time etc.

Plese tell me what exactly what u did to upgrade the BIOS, if the BIOS is flashed wrongly, youy need to throw away your PC.

tap f10 to enter the bios setup
first restore defaults then
go to device configurations and disable the Sata drive, save ur changes and see if u boot. just solved mine now.

at startup press f8 key and last known good configuration
