Try these two troubleshooting methods to gain access into your BIOS. Typically embedded into your computer as a motherboard chip, the BIOS functions as a catalyst for PC functionality action. Newer PCs have replaced the bootstrap loader with an EFI, or Extensible Firmware Interface. I have Windows 7 and it will not wake up. If there is a detected error, BIOS will issue an error message that may come in the form of displayed text or a series of error-indicating beeps. The BIOS system is also responsible for managing data flow between your computer’s operating system and any attached devices including a hard drive, keyboard, video adapter, printer, or mouse. I do believe that those settings gets stored in the registry somewhere. The BIOS and RTC would then revert to its default settings, resulting in, "Press F1 to enter the CMOS setup."

The "boot log" is stored as ntbtlog.txt in whatever folder Windows is installed on, almost always C:\Windows. Why don't libraries smell like bookstores? The BIOS and RTC would then revert to its default settings, resulting in, "Press F1 to enter the CMOS setup." It is a non-volatile firmware which means its settings won’t disappear or change even after power off. The first thing the BIOS does is check the information stored in a tiny (64 bytes) amount of RAM located on a complementary metal oxide semiconductor (CMOS) chip. Instead, they are stored on a special memory chip, which is referred to as "the CMOS." This can also happen with CMOS but due to this purpose it is powered by battery. For example, on Dell systems you will see "F2=Setup" in the upper right hand corner during the computer boot-up. Information stored by the BIOS Setup Utility is essential. Step 1: Enter UEFI firmware settings. The configured data is provided with context-sensitive Help and is stored in the system's battery-backed CMOS RAM. This leaves little room for pressing any hotkeys and can leave those looking to get into their BIOS settings puzzled. Older operating systems tend to load more slowly, so your window of time to press your designated hotkey should be wide enough for prompt BIOS access. Date 2. Due to this reason, you CANNOT press F2 to enter the BIOS configuration when booting the system.. There is pretty much no standardization as to what the individual bytes of NVRAM represent (although there are a couple of common conventions) and their meanings vary from firmware vendor to firmware vendor, and from firmware release to firmware release. Your PC stores all low-level settings like system time and hardware configuration within its CMOS.

Enable Boot Logging . RAM is volatile so when computer turned off, all data lost. complementary metal-oxide semiconductor (CMOS) A type of semiconductor used in firmware such as the BIOS program that retains settings, such as the time, keyboard settings, and boot sequence. That chip is called EEPROM (electrically erasable PROM).BIOS configuration setting is store in special memory called CMOS. If your BIOS isn't updated, it's possible that your computer could have difficulty performing basic tasks, such as interacting with your hardware and making sure the operating system runs quickly and without bugs - especially upon startup.
