When Legacy Boot is Disabled, the check boxes for UEFI Boot Order and Legacy Boot Order will be disabled, because only UEFI devices can boot in this mode. When UEFI Boot Order is enabled, the system attempts to boot from all UEFI devices before any non-UEFI devices. Arrange the boot ...
Legacy initiation of display functions and modes is done by the BIOS, to even show the bootup and BIOS screen. And even that fails. If you had a boot @flips33 and could shuffle above 16GB into your ram without a crash, you have proven that 32GB...
main函数先调用copy_boot_params函数把位于第一个扇区的参数复制到boot_params变量中,boot_params位于setup的数据段,然后调用链为arch/x86/boot/pm.c:go_to_protected_mode(void) --->arch/x86/boot/pmjump.S:protected_mode_jump()。 实模式的protected_mode_jump执行后,跳出了bzImage的第一部分,BootLoader默...
Open the Startup tab and set the startup mode to Legacy (or Both/Legacy First): Press F10 to save changes and reboot. Now, before you process, make sure that AC adapter is connected! If your battery will die during the process, you'll likely need external programmer to recover. Boot ...
BIOS only works in 16 bits and therefore it cannot address more than 1MB of space. As a consequence, it can only initialize one device at a time and the booting might take longer. In contrast, UEFI operates in 64-bit mode, meaning it has higher addressable memory, which speeds up the ...
There are three options in this mode: Legacy, Autonomous, and Disable. Enabled: When “Enabled” is selected, the operating system initiates the C-state transitions. Some OS SW may defeat the ACPI mapping, such as intel_idle driver. Autonomous: When "Autonomous" is s...

Now that we have told you what Unified Extensible Firmware Interface (UEFI) is, it’s time to explain how it differentiates itself from BIOS. For one, BIOS still works in 16-bit mode, which means it can only address 1MB of executable memory. BIOS is also a legacy technology that goes ...
