Why each option

The BIOS contains firmware-level settings that control USB controller behavior, including enabling legacy USB support so that older USB 1.1 devices are recognized during and after boot.

AMBR

The MBR (Master Boot Record) is a disk partition structure that manages bootable volumes and has no role in USB device support or hardware configuration.

BHCL

The HCL (Hardware Compatibility List) is a reference document that lists tested hardware, not a tool or interface used to enable device support.

CBIOSCorrect

The BIOS (Basic Input/Output System) provides low-level hardware configuration options, including enabling or disabling USB legacy support and selecting USB controller modes. Without the correct BIOS setting, a USB 1.1 device may not be detected at the hardware initialization level. No operating system or software tool can override this firmware-level setting.

DAGP

AGP (Accelerated Graphics Port) is a legacy expansion slot for graphics cards and is completely unrelated to USB controller configuration.
