Ubuntu, CentOS, and openSUSE Desktops Focus on Three Major Linux Distribution Families Debian Family Systems (including Ubuntu and Linux Mint).SUSE Family Systems (including openSUSE).Red Hat Family Systems (including CentOS and Fedora).The families and representative distributions this course will focus on are: Instead, I will focus on the three major distribution families. Because there are literally hundreds of distributions, I'm not covering them all in this course. You are about to learn some more details about the many available Linux distributions. In order to fully benefit from this course, you will need to have at least one Linux distribution installed (if you are not already familiar with the term distribution, as it relates to Linux, you soon will be!). And describe the three major Linux distribution families.

U boot x86 how to#
This course will teach you how to navigate Linux's Graphical User Interfaces and powerful command line tool ecosystem. In this comprehensive course, you'll learn many of the tools used every day by both Linux SysAdmins and the millions of people running Linux distributions like Ubuntu on their PCs. If you're new to Linux, this course is for you. > When I use 'bootm' to boot a uImage with uncompressed bzImage, I simply get: > => bootm 2000000 3000000 > # Booting kernel from Legacy Image at 02000000. > However I was unable to proceed some testing to verify this. > This function makes the assumption that the bootable binary is directly > the payload of the u-boot module, > ignoring the work done by "bootm_decomp_image" during the step before > and tries to boot directly in my case a gzip binary. > So the "do_bootm_linux" and finally "boot_prep_linux" from lib/x86, > since wer'e actually running on a x86 machine, is called. > bootm_os_load moves on and finds out that some compressed linux payload > shall be booted. > So, for doing this work, "bootm_decomp_image" is called, > this function uses the image-header for finding out the compression > method and does decompress the real payload to some location. > The task of this "do_bootm_states" is to find out what todo with the > provided image (u-boot module), > is it compressed or not, which kind of os should be booted. => bootm $ > this leads to call (coming through cmd/bootm.c) to "do_bootm_states".
