Advice 1: As in the BIOS to turn on the camera

Basic system I / o or BIOSused for booting and gives the operating system access to hardware resources. If your computer have a video camera, but for some reason does not work, you should check to see whether it is in the BIOS.
As in the BIOS to turn on the camera
Instruction
1
The BIOS is at the beginning of booting the computer. Most often this is pressing the Del key, in the bottom of the screen you will see a banner: Press Del to enter setup. Can use other keys such as F1, F2, F3, F10, Esc, or Ctrl + Alt + Esc.
2
If you enter the BIOS failed, you will see a blue or gray window with multiple tabs. Find the section Advanced and then navigate to it using the keys "Right" and "Left". In this tab select Onboard Device Configuration.
3
Look for the Onboard Device Configuration string to Onboard Camera. Beside her, in the value field must have the value Enabled ("Enabled"). If Disabled (Off), set the desired value using the keys "Up" and "Down".
4
Save the changed settings. To do this, press F10 or select Save and exit setup. In the resulting window, confirm saving the changes by typing Y and pressing Enter. After the reboot, the operating system should see the camera.
5
If in the BIOS the camera is turned on, but still doesn't work, look for item in BIOS Install OS and set beside him the value of Finish. If instead the Finish is the Start, the camera will not work.
6
In that case, if in the BIOS you don't find many items in the settings, you'll likely see an incomplete version. To display all information try pressing Ctrl + F1.
7
Very often problems with the camera are not related to the BIOS, and with the lack of necessary drivers. Check to see if Windows sees the camera, simply right-click on the icon "My computer" on the desktop and select the context menu item "Properties" then "Hardware" - "device Manager". Look for device with yellow exclamation or question mark. Click on it twice with the mouse, select the tab "Driver" and click "Reinstall driver".

Advice 2 : How to enable ahci in the BIOS

You have a modern computer and you bought a new hard drive. You've probably already heard about a new feature NCQ, which was performed on the latest models. You are looking forward to improved boot Windows and noise reduction, Winchester. All that remains is to enter the BIOS and make some changes in the settings.
How to enable ahci in the BIOS
Instruction

If you know of such updates and know what it is, you surely know how to run the BIOS. If not, then restart the computer. During testing the RAM at the bottom of the screen appears Press Del to enter setup. So you have to press the Del button or one that will be shown instead, that might be a key combination to enter the BIOS.

Setting AHCI at the BIOS level is only present in motherboards new generation, where the controller IDE/SATA interface supports SATA II. AHCI is an acronym that stands for Advanced Host Controller Interface. To configure this setting, locate the tab in the ATI SATA Type. The possible values in the tab: Native IDE, RAID, AHCI.
3
In the position of Native IDE appeal to your SATA drives will go, using a mechanism similar to an IDE controller. In this position, do not need additional driver, since all that is necessary for the correct functioning is contained in any operating system. The value of RAID combines hard drives in RAID arrays, the reliability of information storage and speed. To install the required driver on removable media. And finally, the value of AHCI: disk subsystem matters most to high performance in this mode.
4
Similar work is done if the tab is called SATA RAID/AHCI Mode. The only difference is that the mechanism the IDE controller will be used to Disabled. RAID & AHCI settings SATA RAID and AHCI Mode, respectively.
5
If you have a tab, SATA AHCI Mode, there will be values: Enabled (Enabled) or Disabled (Off). The Enabled parameter allows you to take advantage of AHCI mode.
6
To enable AHCI, it is recommended to install the operating system. If you change the mode in the BIOS happened when you installed the system – there will be "blue screen of death". To avoid this, forcibly replace the standard driver IDE/SATA.
7
If it so happens that you have installed the old OS (Windows 9x family), using the AHCI controller is hardly acceptable, as there are no required drivers.
