Compatibility Support Module
[[UEFI]] support booting in BIOS mode from [[MBR]]-partitioned disks through the that provides legacy BIOS compatibility.
In this scenario, booting is performed in the same way as on legacy BIOS-based systems, by ignoring the partition table and relying on the content of a boot sector
BIOS-style booting called BIOS-MBR, regardless of it being performed on UEFI or BIOS. Booting legacy BIOS systems from GPT disks is also possible, and such a boot scheme is commonly called BIOS-GPT.
