Mike,
Del key is the general key to enter most of BIOS, but some BIOS has F2 some F10 and few Esc

You can easily see the button on POST screen, i.e. when you power on your PC just see on screen there may be a message like 'Press Del to enter Setup'

Thanks
Iqbal

How to Bypass BIOS Passwords


BIOS passwords can add an extra layer of security for desktop and laptop computers. They are used to either prevent a user from changing the BIOS settings or to prevent the PC from booting without a password. Unfortunately, BIOS passwords can also be a liability if a user forgets their password, or changes the password to intentionally lock out the corporate IT department. Sending the unit back to the manufacturer to have the BIOS reset can be expensive and is usually not covered in the warranty. Never fear, all is not lost. There are a few known backdoors and other tricks of the trade that can be used to bypass or reset the BIOS v Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself. They include:
Using a manufacturers backdoor password to access the BIOS
Use password cracking software
Reset the CMOS using the jumpers or solder beads.
Removing the CMOS battery for at least 10 minutes
Overloading the keyboard buffer
Using a professional service
Please remember that most BIOS passwords do not protect the hard drive, so if you need to recover the data, simply remove the hard drive and install it in an identical system, or configure it as a slave drive in an existing system. The exception to this are laptops, especially IBM Thinkpads, which silently lock the hard drive if the supervisor password is enabled. If the supervisor password is reset without resetting the and hard drive as well, you will be unable to access the data on the drive.
----------------------------------------------------------------------------------------------------------- Backdoor passwords
Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations. Keep in mind that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops.
WARNING: Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times. Read your manufacturers documentation for the BIOS setting before you begin typing in passwords

How do i reset my computer to an earlier date?


Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!

Would like to know how you access the setup menu or BIOS


I believe that you want to press the F2 button as soon as you turn it on, and keep pressing it until the BIOS setup screen comes up, If F2 doesn't work then try F10

Can't get into the bios for a presario 4716


This is what the Compaq site had to say about the BIOS utility for your system (Source: Compaq): • • • •You may have difficulty accessing the BIOS Setup utility screen, because you must press a specific key(usually F1) very quickly before the Windows screen appears. If you do not enter the BIOS Setup screen on your first try, repeat the following steps until you are successful.

To open the BIOS Setup screen:
1. Turn off the PC and wait about 5 seconds.
2. Turn on the PC.
3. When the first screen appears, press the F1 key on the keyboard. (You can press the key more than once.) The BIOS Setup Utility Main menu appears.
NOTE: On certain Compaq Presario PCs (prior to 2002) press the F10 key at the logo screen to enter setup.
4. Use the keyboard to navigate through the menus.
You may need to remove the battery and then back in.

How do you enter set up in an oler compaq presario. It came with win 98.also if hard drive controller is bad can I put in a new one without replacing motherboard


Hi,

Depending on the actual model of the old Compaq, you can enter the CMOS/BIOS setup by pressing on the a special function key or key combination during Power-On Self Test (POST), before the operating system loads. During POST, the BIOS usually displays a prompt such as:
Press F2 to enter Setup
Common keystrokes that will access the BIOS Setup are F1, F2, F10, and Del. For older Compaq computers, like the Deskpro 286 or 386, you must place the Diagnostics diskette in the A: drive, and then restart the computer.
For newer Compaqs, like the Prolinea, Deskpro XL, or Presario, while the cursor is at the top right corner of the screen during bootup, press the F10 key.

The hard drive controller can not be replaced without replacing the motherboard. Incidentally, there are old PCI sundcards that has an IDE port and can be configured to replaced defective on-board IDE port.

If your concern has not been addresses after completion of the above procedures, you may need to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Add more memory to my computer


Not able to access it in what way? Is there a password for the BIOS or something? Normally on most (all?) Compaq models, F10 is the key to use to access the BIOS.
