BIOS is fixed program that starts up the computer. BIOS is initialized during start up of HP Compaq-6715B which sets the computer settings to be uploaded. BIOS enables the creation of a bootable diskette, CD, or USB key that can be used to locally restore or upgrade the System BIOS in the supported notebook models with a 68YTT Family ROM. Only insert the USB drive that will be used to format and create bootable BIOS upgraded USB media. However, you should remove all unused USB drives and flash drives from the notebook before. In order to ROM family and ROM date, press F10 on the target notebook during startup to run the setup utility.
The tips to get into the BIOS of HP Compaq-6715b are:
BIOS often has a blue background, and uses the arrow keys, PageUp, PageDown and enter keys to change the settings. After you have got into or accessed the BIOS, you can change the boot order settings so that the floppy disk is checked first to see if it contains a bootable program. Usually a message will appear telling you how to enter the BIOS setup program as the computer starts up, such as Press F2 for Setup.
Your HP Compaq-6715b might be configured to show your computer's logo instead of important BIOS messages. In this case, you can press Esc or Tab while the logo screen is visible. If you are facing problems pressing the pause button in time, turn on your computer with your keyboard unplugged. In this situation you will receive a keyboard error, which helps you in pausing the startup process long enough for you to see the keys necessary to enter BIOS.
Independent of OS
The PCs with both PS/2 and USB connections are configured to only allow USB input after the POST. If you are using a USB keyboard, it could be impossible to access BIOS. You would need to connect an older PS/2 keyboard to your PC to access BIOS. The BIOS accessing is independent of any Operating System on your computer because the BIOS is part of your motherboard hardware.
