BIOS

[ColaBoy]

Ive just started a PC repair course and have just covered the BIOS. One thing that I am still unclear on is whether BIOS actually gets loaded into the systems RAM as there is an address allocated for it. This leads me to ask why does it need to be loaded in RAM,why can't it be run directly from the CMOS chip?

Well after the bios hands over control to the O.S. the cmos settings are no longer needed but the bios keeps translating communications between the cpu and other components.
Am I on the same page as you? :look:

Part of the Basic Input Output System is loaded into ram quite simply because it's a darn sight faster to access than the ROM it resides on... not all of the contents are loaded into RAM however. only the parts the O.S needs for it's general operation.
