qloader2

x86/x86_64 BIOS Bootloader

How to use

This repository contains a prebuilt version of qloader2 so building it won't be necessary.

In order to install qloader2 on a device (which can just be a raw image file), run the provided qloader2-install script as such:

./qloader2-install ./qloader2.bin <path to device/image>

Then make sure the device/image contains at least 1 partition formatted in echfs containing a qloader2.cfg file and the kernel/modules one wants to load.

An example qloader2.cfg file can be found in test/qloader2.cfg.

For example, to create an empty image file of 64MiB in size, 1 echfs partition on the image spanning the whole device, format it, copy the relevant files over, and install qloader2, one can do:

dd if=/dev/zero bs=1M count=0 seek=64 of=test.img
parted -s test.img mklabel msdos
parted -s test.img mkpart primary 1 100%
echfs-utils -m -p0 test.img quick-format 32768
echfs-utils -m -p0 test.img import path/to/qloader2.cfg qloader2.cfg
echfs-utils -m -p0 test.img import path/to/kernel.elf kernel.elf
echfs-utils -m -p0 test.img import <path to file> <path in image>
...
./qloader2-install $THIS_REPO/qloader2.bin test.img

One can get echfs-utils by installing https://github.com/qword-os/echfs.
