What is CSM UEFI?
CSM is an abbreviation for compatibility support module. It’s an optional utility included in the UEFI firmware that enables compatibility with classic BIOS. CSM provides backward compatibility by booting the system as though it were using a traditional BIOS. Additionally, it permits the usage of older operating systems that do not support UEFI.
What is UEFI firmware configuration?
Unified Extensible Firmware Interface (UEFI) is a standard for a software program that links the firmware and operating system of a computer (OS). It is anticipated that UEFI would ultimately replace BIOS, however it is compatible with BIOS.

Can UEFI launch MBR?
UEFI facilitates greater utilization of larger hard disks. UEFI supports the traditional master boot record (MBR) method of hard drive partitioning, but it goes beyond that. It is also capable of functioning with the GUID Partition Table (GPT), which is not constrained by the MBR in terms of partition size and number.
Is UEFI superior than BIOS?
UEFI is more powerful and has more sophisticated capabilities than BIOS. It is the most recent form of computer booting, intended to replace BIOS. UEFI is, in summary, the successor of BIOS.
Is UEFI firmware similar to BIOS?
No, they are dissimilar! BIOS and UEFI are two firmware interfaces for starting the operating system on a computer. The Master Boot Record (MBR) is used by BIOS to store information about hard disk data, while the GUID Partition Table is used by UEFI (GPT).
Can traditional BIOS boot UEFI?
In general, Windows should be installed using the more modern UEFI mode, since it has more security measures than the outdated BIOS mode. If you are booting from a network that supports just BIOS, you must boot into legacy BIOS mode. After Windows has been installed, the device immediately boots in the same mode it was installed in.
