    1. Open your computer case

    2. Find your CMOS Battery on the motherboard (looks like a large watch battery)

    3. Take the battery out for 30 secs and put it back in

    4. BIOS Resets

    if you have such a memory option on your bios it will apparently be shown in your bios menu.
    You'd have to consult the manual that came with your computer. There

    are several different manufacturers of CMOS chips, as well as a great

    many versions of each BIOS.

    These controls are located in a part of the system called "BIOS Settings", "BIOS Menu", "CMOS settings", "CMOS setup" or some similar variation. This should be covered in your user manual.



    You usually enter "BIOS Settings" menu by pressing a specific key or keys during the beginning of the boot-up process. The specific key(s) to press are usually mentioned in a corner of the display as the system boots. They should also be in the manual. It is sometimes the "F2" key, or "Del", or a combination like "Ctrl+S" keys.



    Once you've entered the menu, you'll see it provides many parameter settings organized in "pages". Basically, walk through the on-screen prompts until you see the settings having to do with cacheing and shadowing.



    Every system and even current BIOS version has
    a different way to present these data, so we generally can't give you a
    specific keystroke-by-keystroke set of instructions. Again, your user
    manual should detail this information.



    If you don't have a current user-manual, you should be able to go to the motherboard or system manufacturer's website to download a copy. It will usually be in .pdf format which will (in order to be able to read it) require a free .pdf reading application like Adobe Reader or Foxit.

Unmountable boot


Hi
You will need to get the original windows disk you was sent.
Put it in the laptop and run the 'RECOVERY CONSOLE'
this should bring up a command line, (command prompt)

Type :
1. fixboot
2. chkdsk /r /f

If they both fail you will either have to put your hard drive on a cradle and write another boot directory to it, or you will have to reformat it.

Unmountable boot volume or do I need another hard drive ?


Start machine press F8 repeatedly
If it lets you into Safe Mode then go to Programs, Accesories, System Tools, System Restore and try to roll the machine back a week or so
If that does not work you need to find a buddy with a copy of the software and reinstall providing your machine has the Windows sticker on the back or sides giving you the key code

Dell Latitude c640 Disable BIOS memory


Just use recovery console of windows xp bootable media and use the following command.

chkdsk (to check the volume).
fixmbr
fixboot

It happens due to improper shutdown methods which has caused the system volume to corrupt the MBR.
