;D ;DI hope you will all bear with me on my Pet Subject that most people want to ignore?Firstly, what is CMOS?Originally it was a Tiny little bit of Memory, protected by a Battery to ensure it would always be independentant and make a Computer start up correctly, and in the early days could not be altered in any way. It still remains in all Modern day Computers.Let these people first tell you, then I will add my bit.
CMOS controls a variety of functions, including the Power On Self Test (POST). When the computerâ€™s power supply fires up, CMOS runs a series of checks to make sure the system is functioning properly. One of these checks includes counting up random access memory (RAM). This delays boot time, so some people disable this feature in the CMOS settings, opting for a quick boot. If installing new RAM it is better to enable the feature until the RAM has been checked. Once POST has completed, CMOS runs through its other settings. Hard disks and formats are detected, along with Redundant Array of Independent Disk (RAID) configurations, boot preferences, the presence of peripherals, and overclocking tweaks. Many settings can be manually changed within the CMOS configuration screen to improve performance. However, changes should be made by experienced users. Changing settings improperly can make the system unstable, cause crashes, or even prevent the computer from booting. The CMOS configuration screen is accessible during the POST phase of boot up, by pressing a key before the operating system initializes. Normally this is the Del key but it might be another. A line of text will indicate which key will take the user into the CMOS or BIOS setup screen. Changes cannot be made from within an operating system such as Microsoft Windows, but must be made within a true DOS session. There is also an option to protect CMOS settings by requiring a password to change settings. Changes are saved upon exit by pressing the F10 key, then the computer reboots to utilize the new settings.

All of a sudden that tiny Memory that starts your Machine has been contromised? Anyone can now alter it?Can you Guess where the Major Companies and Viruses Target?How many Machines have been thrown away from that?I have saved so many Machines, just by Draining the CMOS, either by removing the Battery, or using the Jumpers, then resetting to current Time and Date and in other Times when neccessary Reformat and reinstall. Never lost one Machine.Big Companies have made a Fortune on other Gear that refuses to recognise CMOS. They would give away their Money, if they did? ;D ;DNovember 12, 2009 at 11:57 am #32565
;D ;DQuite often, in a big Virus Hit, Draining the CMOS, not renewing the current Date and Time settings, then Running your Anti-Virus and Anti-Malware Gear in Safe Mode will fix it. It screws up the Command Input,from the Intruder, because it is underdated, meaning in some cases years before, whereas the Intruder is on a limited Time Frame.
