Setting ACPI OS String Parameter to Windows 2015

Setting an ACPI OS String Parameter in Windows 10 (2015)

In this article, we will discuss how to set an ACPI (Advanced Configuration and Power Interface) OS string parameter in Windows 10 (2015). This is a common task for system administrators and power users who want to customize their operating system to work with specific hardware or software configurations.

What is an ACPI OS String Parameter?

An ACPI OS string parameter is a value that is passed from the operating system to the BIOS (Basic Input/Output System) to indicate the capabilities and requirements of the operating system. This can include information such as the operating system version, the type of processor, and the amount of memory installed in the system.

Why Set an ACPI OS String Parameter?

Setting an ACPI OS string parameter can be useful in a number of situations. For example, if you are using hardware or software that is not fully compatible with your operating system, you may be able to set an ACPI OS string parameter to indicate the specific version or configuration of the operating system that the hardware or software requires. This can help to ensure that the hardware or software functions correctly and that the system is stable.

How to Set an ACPI OS String Parameter in Windows 10 (2015)

To set an ACPI OS string parameter in Windows 10 (2015), you will need to use the dmesg command in the Command Prompt. The dmesg command displays the kernel ring buffer, which contains information about the system's hardware and software configuration. By using the grep command to filter the output of the dmesg command, you can find the current value of the ACPI OS string parameter and change it to the desired value.

Here are the steps to set an ACPI OS string parameter in Windows 10 (2015):

1. Open the Command Prompt as an administrator.
2. Type the following command to display the kernel ring buffer: sudo dmesg
3. Use the grep command to filter the output of the dmesg command and find the current value of the ACPI OS string parameter. For example, to find the value of the acpi_osi parameter, you can use the following command: sudo dmesg | grep -i added | grep acpi_osi
4. If the desired value of the ACPI OS string parameter is not already set, you can use the echo command to set it. For example, to set the acpi_osi parameter to the value 2015, you can use the following command: sudo echo "acpi_osi=2015" > /sys/module/acpi/parameters/acpi_osi
5. Verify that the ACPI OS string parameter has been set to the desired value by using the dmesg and grep commands again.

Setting an ACPI OS string parameter in Windows 10 (2015) is a simple process that can be done using the Command Prompt and the dmesg, grep, and echo commands. By setting the appropriate ACPI OS string parameter, you can ensure that your operating system is properly configured to work with specific hardware or software configurations, which can help to improve system stability and performance.
