Basic Input/Output System (BIOS)

Posted on March 5, 2007

Motherboard BIOSThe system BIOS is actually a combination of software and hardware and is sometimes referred to as firmware. The data in the BIOS is held in ROM (read-only memory) The main functions of the BIOS is to hold the instructions that start up the computer and to manage the system devices from CMOS setup, such as power saving features, plug and play settings, keeping track of the current time and identifying which hardware devices are present. Sometimes when a computer component is added or updated on a system or when a newer device driver is preferred, it becomes necessary to upgrade the ROM BIOS. In years past, this process involved buying the new ROM chip and exchanging it on the motherboard. Now with modern technology, ROM chips on the motherboard are made to be re-programmable and the data on the chip can be overwritten by a process called Flash ROM without removing it.

    Joe,

    I am using a theme called Vertigo Electrified, that I have modified. This has been a good theme and has withstood many upgrades and my own adaptations along the way, going from WP 2.0 to now running WP 2.6 newest version.

    Thank you for the input! :lol:

    Interesting point of view. I’ll consider changing my mind about this but for now I still don’t see things the same way you do.

    I dig what you’re saying but there’s a lot more to this than meets the eye, like Transformers! -Roulette King
