How to turn off uefi on HP Desktop?

How to turn off uefi on HP Desktop? Can you turn it off? Follow me! Let me give you a detailed introduction on how to turn off uefi on the desktop! I hope it helps you!

Uefi method of HP desktop office 1:

According to your description, I suggest you refer to the following information:

If you want to start normally, you can click F9 continuously to open the startup sequence, and then select the CD-ROM startup under the Legacy startup sequence or the startup item you want (by default, UEFI startup takes precedence over Legacy mode and needs to be adjusted manually).

I hope the above reply can help you.

If the above information can't solve your problem, you can log on to the HP online chat room to consult an online engineer to help you solve the problem further.

Uefi method of HP desktop organization 2:

1, xp system was released earlier, and dual graphics cards were not released at the time of release, so xp system does not support dual graphics cards, so you can't use discrete graphics cards normally after installing xp system. If you don't have to use xp system, it is recommended not to install an operating system using xp.

2. At present, there is no good way to disable the integrated graphics card of the machine directly in the BIOS.

Uefi purpose

BIOS is the basic input and output system, which is translated into Chinese as "basic input and output system", and it is a kind of so-called "firmware", which is responsible for the startup and detection of hardware during booting and acts as an intermediary role when the operating system controls hardware.

Due to the rapid development of hardware, the traditional BIOS has become a burden of progress. Now, the latest UEFI (Unified Extensible Firmware Interface) extensible firmware interface has been developed. Compared with the traditional BIOS, the future will be a computer era without a specific BIOS.

Compared with the traditional BIOS, UEFI has several biggest differences:

1.99% of the coding is done in C language;

2. Change the previous methods of interrupt and hardware port operation, and adopt a new driver/protocol mode;

3. X86 real mode will not be supported, and Flat mode will be adopted directly (that is, DOS cannot be used. Now some EFI or UEFI can be used because of compatibility, but in fact this part does not belong to the definition of UEFI);

4. The output is no longer a simple binary code, but a movable binary driver;

5.OS startup is no longer calling Int 19, but directly using the protocol/device path;

6. For the development of third parties, the former is basically impossible unless you participate in the design of BIOS, but it is also limited by the size of ROM, while the latter is much more convenient.
