Please notice I'm not English native and, someone like you, whom might be English native might be more suited than me in order to collect all the knowledge related to this feature and write its nice documentation. I'm not going to unveil you the last bits of what you need (not yet but I will) so that you leave and the documentation is once again unfinished and unpolished. So far you have not said if you were willing to document it or not. #Locad iso in ram grub2 how to#) documenting this process so that future distro developers know how to use this specific feature. My primary need is having someone else (i.e. My primary need is purely to understand SG2D requirement for booting an ISO from /boot/boot-isos specifically the process with the loopback.cfg requirement and how to setup for SG2D selection of the ISOs in that folder. The kernel reads his boot parametres which one of them says: Now either the kernel either has integrated filesystem modules or they will later be embedded into the initrd. So this program Linux (as in Linux kernel) which is loaded into RAM only knows how to talk to the CPU and how to write and read into the RAM. Instruct the CPU to load the kernel program.Uncompress and load initrd into RAM just after the kernel.Mount the partition where kernel and initrd are to be found. #Locad iso in ram grub2 code#One of the partitions next to the /boot/grub/grub.cfg path is hardcorded into grub2 boot code specific for your machine. That means it can read files from the computer. Thanks to its filesystem modules it manages to read the hard disk contents, its partitions and its partition filesystems. So this program grub2 which is loaded into RAM only knows how to talk to the CPU and how to write and read into the RAM. Menuentry "Live system, kernel 4.19.0-6-amd64" grub variable to:Įither thanks to UEFI or to BIOS an small (or bigger) program called boot loader is loaded into RAM.īack in the day this program might be lilo or grub legacy. Set theme=/boot/grub/live-theme/theme.txt # binary_syslinux modifies the theme file to point to the correct Thanks in advance to anyone who is willing to guideīTW: The picture on SG2D beta2 webpage ( ) does not match the current ISO/IMG. I am clueless to begin assembly of one for SG2D selection for boot. I am appealing, here on GIT, for guidance using a Puppy Linux distro's ISO as a test for creating a loopback.cfg file on a PUP which is booting a GRUB2 boot-manager (grub.cfg).
