When updating bios what is important
With the POST completed, the BIOS then attempts to load the operating system through a program known as a bootstrap loader, which is designed to locate any available operating systems; if a legitimate OS is found, it is loaded into memory. These are programs designed to give the computer basic control over hardware devices such as mice, keyboards, network hardware and storage devices.
The BIOS can also play a role in computer security.
BIOS enables computers to perform certain operations as soon as they are turned on.
The principal job of a computer's BIOS is to govern the early stages of the startup process, ensuring that the operating system is correctly loaded into memory.
If you are not confident doing the update yourself you should contact your laptop manufacturer's local service specialist.
The BIOS software itself generally resides on a Read-Only Memory, or ROM, or a flash memory chip attached to your computer's motherboard.
BIOS is the very first piece of software that runs when your computer turns on, and makes sure your computers components (Network adaptors, Graphics cards, etc) are running properly.
BIOS is gradually being phased out for a similar system called EFI or UEFI (Unified / Extensible Firmware Interface).
If you are using a host bus adapter (HBA) card that was not shipped with your system, you might need to update the firmware on your HBA card to support the Unified Extensible Firmware Interface (UEFI) BIOS.
The following HBA cards might need updating: You can use Oracle Hardware Management Pack to update your HBA firmware.
