The Compatibility Support Module (CSM) is a part of the UEFI firmware that provides legacy BIOS compatibility by emulating a BIOS environment, allowing the use of legacy operating systems and some option ROMs not support UEFI.[48]January 20, 2016.
Should you disable CSM?
You must ensure your PC’s hard drive and operating system are configured to run in UEFI mode. Disabling CSM will disable Legacy Mode on your motherboard and enable the full UEFI mode your system requires.
What are CSM boot and UEFI boot?
Legacy (CSM) and UEFI are different ways to boot from storage drives (which today often take the form of SSD). CSM uses an MBR (Master Boot Record) in a specific format of 512 Bytes to boot the operating system. UEFI uses files within a large partition (usually 100MB) to boot the operating system.
How do I disable CSM?
Look for a setting called “Boot Mode”, “UEFI Boot”, “Launch CSM,” or whatever it is called, and change the boot mode from UEFI to Legacy/CSM: disable the UEFI Boot option and disable CSM Boot- support. Save your changes and exit UEFI Setup.
Is CSM the same as a secure Boot?
CSM support is used for booting from older devices, which is the opposite of Secure Boot. Custom would allow us to set the keys used for attestation to Secure Boot.
Is CSM necessary?
You don’t need to enable it. It is only necessary if you need to install an older operating system that does not support UEFI. If you’ve messed around with the BIOS settings, reset it to defaults and see if your PC reboots.
Can I switch from CSM to UEFI?
1 Answer. If you switch from CSM/BIOS to UEFI, your computer won’t boot. Windows does not support booting from GPT drives in BIOS mode, meaning you must have an MBR drive, and it does not support booting from MBR drives in UEFI mode, meaning you must have a GPT drive. To have.
Is UEFI better than legacy?
Compared to Legacy, UEFI has better programmability, greater scalability, higher performance, and higher security. UEFI provides a secure boot to avoid loading several on the Boot. Windows system supports UEFI from Windows 7, and Windows 8 uses UEFI by default. B
Which boot mode should I use, UEFI or legacy?
In general, install Windows with the newer UEFI mode, as it contains more security features than the old BIOS mode. If booting from a network that only supports BIOS, you must boot into legacy BIOS mode. After Windows is installed, the device will automatically kick into the same mode it was established.
What is UEFI Boot Mode?
UEFI stands for Unified Extensible Firmware Interface. UEFI provides security such as “Secure Boot”, which prevents the computer from booting from unauthorized/unsigned applications. UEFI has discrete driver support, while BIOS has disk support stored in the ROM, so updating BIOS firmware is difficult.
What happens if I disable legacy support?
New member. In my previous system, disabling legacy support meant that the bios couldn’t use USB and socouldn’t boot from a USB drive. In the future, remember that you may need to re-enable it to use USB on Boot.
What is ErP in BIOS?
What does ERP mean? ERP mode is another name for a state of BIOS power management functions that instructs the motherboard to turn off power to all system components, including USB and Ethernet ports, meaning your connected devices will not be charged while in low power consumption.
What is CSM in Nursing?

What is CSM in Boot Options?
The Compatibility Support Module (CSM) is a part of the UEFI firmware that provides legacy BIOS compatibility by emulating a BIOS environment, allowing the use of legacy operating systems and some option ROMs not support UEFI.
What is Fast Boot in BIOS?
Fast Boot is a feature in the BIOS that reduces your computer’s boot time. When Fast Boot is enabled: Boot from the network, optical and removable devices are disabled. Video and USB devices (keyboard, mouse, drives) are unavailable until the operating system is loaded.
How do I change my BIOS to UEFI?
Select UEFI Boot Mode or Legacy BIOS Boot Mode (BIOS). Enter the BIOS Setup Utility. Select Boot from the BIOS main menu screen. Select UEFI/BIOS boot mode at the boot screen and press Enter. Use the up and down arrows to choose Legacy BIOS Boot Mode or UEFI Boot Mode, then press Enter.

Do I need to enable UEFI in the BIOS?
Many computers with UEFI firmware allow you to enable an older BIOS compatibility mode. In this mode, the UEFI firmware functions as a standard BIOS instead of UEFI. You will find this option in the UEFI settings screen if your PC has this option. You should only enable this when necessary.
Can I use Windows 10 in old mode?
Steps to Enable Legacy Boot on Any Windows 10 PC Most current configurations support Legacy BIOS and UEFI boot options. However, if you have a Windows 10 installation disc with an MBR (Master Boot Record) partitioning style, you cannot boot and install it in UEFI boot mode.
Can UEFI MBR boot?
UEFI may be faster than BIOS. While UEFI supports the traditional MBR (Master Boot Record) method of partitioning hard drives, it doesn’t stop there. It can also work with the GUID Partition Table (GPT), free from the MBR’s restrictions on the number and size of partitions.
