The difference between UEFI BIOS and ordinary BIOS is: different installation system, different DOS and different output.

First, the installation system is different.

1, UEFIBIOS: UEFIBIOS installs the system in UEFI+GPT mode.

2. Ordinary BIOS: Ordinary BIOS installs the system in legacy+MBR mode.

Second, DOS is different

1, UEFIBIOS: UEFIBIOS does not support X86 mode, but directly adopts Flat mode instead of DOS.

2. Ordinary BIOS: Ordinary BIOS supports X86 mode and can use DOS.

Third, the output is different.

1, UEFIBIOS: UEFIBIOS outputs a removable binary driver instead of a simple binary code.

2. Ordinary BIOS: The output of ordinary BIOS is simple binary code.
