It provides instructions to the computer system for performing several types of important functions like keyboard control and booting of the computer etc.. BIOS is used for the purpose of the identification and the configuration of the … In computing, BIOS is firmware used to perform hardware initialization during the booting process (power-on startup), and to provide runtime services for operating systems and programs. Some motherboards have a feature called ErP, which allows the PC to consume the least amount of power possible, but not completely to 0W. While the common practice is still to use the term “BIOS”, most … This option is useless without that sensor. CPU Ratio: This allows you to change the frequency multiplier of the processor. The name originates from the Basic Input/Output System used in the CP/Moperating system in … Typical speed settings include letting the system adjust the fan speed based on noise/performance profile or setting it to a flat value. APIC Mode : Enabled. The BIOS includes instructions on how to load basic computer hardware. It's best to leave this alone unless you've been touching BLCK, run into stability issues, and have run out of other options to tweak. This setting only applies to users running the now defunct OS/2 operating system from IBM. How to add features to BIOS? I loved your well described article. UEFI replaces the legacy Basic Input/Output System (BIOS) firmware interface originally present in all IBM PC-compatible personal computers, with most UEFI firmware implementations providing support for legacy BIOS services. But the most important ones are: CAS LatencyRAS to CAS delayRow Precharge TimeRAS Active Time. The BIOS is Insyde F.29. Everything else shuts off. Unless you suspect a problem with either one, I see no reason to continually test them with BIOS diagnostics. Visit our corporate site. Advanced Features. Features vary among individual BIOS versions. They allow you to configure the underlying hardware settings of your computer, including which device will be used to boot the PC and in what order they will be polled. BCLK/Base Clock: This is the main system clock for the processor. S3: Standby/Sleep/Suspend to RAM. You are the first person I have seen online to acknowledge that the power management contained in the software does not mesh well with the hardware. Intel Rapid Start: A way to resume from hibernate very quickly. Older versions of Windows and OS/2 perform better with this parameter set to FAST. BIOS is an important feature of the computer system that regulates its normal functioning. Boot/POST beep: Leave this on, as this will aid in troubleshooting if the computer doesn't boot up. These are the four numbers you see in memory timings on product specifications. This option may be simplified to just acting on the chipset temperature, as processors have gotten really good at preventing catastrophic overheating. Gate A20 Option : FAST. Compared with BIOS, UEFI is more powerful and has more advanced features. The "traditional" way to check the BIOS … If you can't use a BIOS key and you have Windows 10, you can use the "Advanced startup" feature to get there.

When a computer starts (power is first applied) there must be some program code which the CPU executes. On Intel machines, it may be called VT-x, while AMD machines it may be called AMD-V. On older machines, it'll be called "Vanderpool.". During the POST mentioned earlier, the BIOS checks the hardware devices and counts the system memory. Out of all the different types of system memory, the random access memory, better known as RAM, takes the longest to be checked. For example, if you have header names FAN_1, FAN_2, and FAN_3, these should correspond to Fan 1, Fan 2, and Fan 3 in the BIOS respectively. Note that some motherboard manufacturers may put this in another location (ASRock for instance, puts this in Chipset Configuration).

For example, your system manufacturer might release a BIOS update in order to run the latest version of Windows 10 more smoothly or add support for some features. BIOS has become more peripheral, with the development of 32-bit and later architectures. This doesn't reduce the total amount of EMI, but it helps prevent all of it from being concentrated on the frequency of interest, namely the processor's clock frequency. This setting, when enabled on a PC with speakers, will "talk" over your speakers at boot time to tell you the status of the POST.
