Definition
check whether the motherboard has a jumper than can be removed to make CMOS forget passwords.
Remove the CMOS battery from the otherboard
get a CMOS utility, CMOS Save & Restore Utility. It backs up the CMOS info and allows you to restore it when an emergency arises. you must backup CMOS before a password is set. |

BIOS security feature on laptops
created by Absolute Software, allows the laptop to connect to Absolute's servers to specific the laptop location and verify if the laptop was reported stolen.
allows companies and law enforcement to track location of stolen property.
it is disabled by default but can be enabled by purchasing a license key from Absolute software. |

Term
| Plug and Play BIOS (PnP BIOS) |
|
Definition
connect new device to the system and have it automatically detect and configure the device to work with your system.
must meet 3 conditions to work:
- a PnP device
- a PnP OS
- a PnP BIOS |
|
|
Term
| Globally Unique identifier (GUID) |
|
Definition
128-bit number stored in CMOS. it uniquely IDs the system from any other like a social security number.
sometimes referred to as Universally Unique Identifier (UUID) |

|
Term
| BIOS date and revision number |
|
Definition
located in CMOS usually under Summary.
Revision number is identified by the label 'Flash EEPROM Revision Level.'
important for updating BIOS. |
|

1. the network card enabled
2. system has enabled booting off the network adapter
3. network device is located in the startup order of devices. |

|
Definition
| Intel developed standard that allows software to comm with SATA devices and take advantage of SATA features like hot-swapping. |
|
|
Term
|
Definition
| aka IDE compatibility mode or ACPI. Emulates IDE and should be used if you are installing an older operating system that does not have SATA drivers for your drive. |
|
|
Term
|
Definition
| enables SATA mode and should be used to gain the performance benefits of SATA if your OS has a SATA driver. If the installation of the OS does not detect the drive, try switching to IDE compatibility mode/PATA Emulation. |
|
|
Term
|
Definition
| used to support SATA in a RAID configuration |
|
|
Term
|
Definition
non-PnP devices that have been added to the system that may need configuration in CMOS to reserve the IRQ so it is not given to a PnP device on startup.
only a problem when using newer OSes on older hardware. |

Definition
-the BIOS is low-level code used by the system to communicate with the system hardware. The BIOS code is stored on an EEPROM chip located on the motherboard of the system
- the BIOS is typically updated by downloading a BIOS update program and "flashing" the BIOS
- you enter a systems CMOS setup program by using a keystroke such as F1 (IBM), F2 (Dell), or F10 (compaq) when the system starts up.
- you can change the boot order of the different bootable devices
- the three parallel port modes are SPP, EPP, and ECP
- You can change the hard drive from autodetect to manual so you can input the drive dimensions
- in order to support virtualization technology, you must have enabled virtualization support in the BIOS
- You can update your BIOS by downloading the BIOS update for your system from the BIOS manufacturer |
