Das U-Boot (subtitled the Universal Boot Loader and often shortened to U-Boot; see History for more about the name) is an open-source, primary boot loader used in embedded devices to package the instructions to boot the device's operating system kernel. It is available for a number of computer architectures, including 68k, ARM, Blackfin, MicroBlaze, MIPS, Nios, SuperH, PPC, RISC-V and x8 A VII típusú német tengeralattjárók voltak a német U-boot-flotta (tengeralattjáró) igáslovai a második világháborúban.A VII típus az E-2 típuson alapult, melyet a német Deschimag nevű vállalat fejlesztett ki a szovjet haditengerészetnek (a Szovjetunióban IX sorozatként gyártották). A VII típusú U-bootok voltak a második világháború legelterjedtebb.

UBot Studio is a web automation program for marketers, programmers, entrepreneurs, and anyone who uses the web. Build simple automation tools using a drag-and-drop interface on any site U-Boot also alters the device tree to tell the kernel where the ramdisk image is located in memory (initrd-start and initrd-end). The bootm command sets the r2 register to the address of the device tree in memory which is not done by the go command U-Boot (en inglés y en otros idiomas U-boat), abreviatura del alemán Unterseeboot, «nave submarina», en plural U-Boote, es la denominación dada a los sumergibles y submarinos alemanes desde la Primera Guerra Mundial.El principal escenario donde actuaron fue el océano Atlántico y el mar del Norte y rara vez el océano Índico u océano Pacífico.. Le terme U-Boot (abréviation d'Unterseeboot qui signifie sous-marin en allemand, au pluriel U-Boote selon la graphie allemande, ou U-Boots selon la réforme de l'orthographe de 1990) désigne les sous-marins allemands des deux guerres mondiales.Ils sont surtout célèbres pour leurs campagnes d'attaques de convois de ravitaillement partant des États-Unis et du Canada pour l'Europe

In this case the bootm command consists of three steps: first the Linux kernel image is uncompressed and copied into RAM, then the ramdisk image is loaded to RAM, and finally control is passed to the Linux kernel, passing information about the location and size of the ramdisk image.
