Unlike PC bootloaders which obscure or automatically choose the memory locations of the kernel and other boot data, U-Boot requires its boot commands to explicitly specify the physical memory addresses as destinations for copying data (kernel, ramdisk, device tree, etc.) and for jumping to the kernel and as arguments for the kernel.

There are also commands to read device information, read and write flash memory, download files (kernels, boot images, etc.) from the serial port or network, manipulate device trees, and work with environment variables (which can be written to persistent storage, and are used to control U-Boot behavior such as the default boot command and timeout before auto-booting, as well as hardware data such as the Ethernet MAC address). Using the CLI, users can load and boot a kernel, possibly changing parameters from the default.

U-Boot runs a command-line interface on a console or a serial port. UEFI binaries like GRUB or the Linux kernel can be booted via the boot manager or from the command-line interface. U-Boot implements a subset of the UEFI specification as defined in the Embedded Base Boot Requirements (EBBR) specification. Regardless of whether the SPL is used, U-Boot performs both first-stage (e.g., configuring memory controllers and SDRAM) and second-stage booting (performing multiple steps to load a modern operating system from a variety of devices that must be configured, presenting a menu for users to interact with and control the boot process, etc.). If there are size constraints, U-Boot may be split into stages: the platform would load a small SPL (Secondary Program Loader), which is a stripped-down version of U-Boot, and the SPL would do initial hardware configuration and load the larger, fully featured version of U-Boot. onchip ROM of the ARM CPU) from a supported boot device, such as an SD card, SATA drive, NOR flash (e.g.

Here is how to set up a Mac, running OS X Client 10.5 or later, as a PXE boot server.

I'm trying to PXE-boot a Cisco UCS C240 server to install a new OS over the network, but it isn't picking up an IP address via DHCP during boot. At this point the client receives the boot information from the PXE proxy and tells the client to continue with a network boot. This message contains the clients, MAC address, the IP address the server is offering, the subnet mask, the lease duration, and the IP address of the DHCP server making the offer. By default, when a PXE client boots up, it will use its own MAC address to specify which configuration file to read, so we need to create that default file that contains the list of kernels which are available to boot. The PXE configuration file defines the boot menu displayed to the PXE client when it boots up and contacts the TFTP server.
