First in plaintext encryption, to change the configuration file, in the /etc/grub.conf.2. Open the/etc/grub.conf file with VI or vim .add a line after Hiddenmenu, enter:password 123 (123 is the password you want to set). and then save. 3. This is to set plaintext encryption to grub menu, to grub menu set ciphertext encryption, first with md5 set

Default, the Raspberry Pi kernel boots with device tree enabled. You can
Completely disable DT usage (for today) by adding:

the computer boots, the BIOS directs the PXE client into memory and then the files that are placed at the remote end by the PXE client are downloaded locally to run on the network. Running the PXE protocol requires setting up a DHCP server and a TFTP server. The DHCP server assigns an IP address to the PXE client (the host that will install the system), and because it assigns an IP address to the PXE client, the appropriate PXE settings need to be ad

I. Concepts and principlesWhat is PXEstrictly speaking, PXE is not a way to install, but a way to boot. A requirement for a PXE installation is that the computer to be installed contains a PXE-supported network card (NIC), which must have a PXE Client on the network card. PXE (Pre-Boot execution Environment, the pre-launch Execution Environment) protocol enables a computer to boot over a network. The protocol is divided into client and server side, the PXE client is in the ROM of the NIC, when t
