# Introduction
|
|
|
|
Matos is a simple OS.
|
|
|
|
It's targetting x86 and inspirated by http://sos.enix.org/fr/PagePrincipale
|
|
|
|
|
|
|
|
# Dependencies
|
|
|
|
To generate iso image
|
|
|
|
* `mtools xorriso (which is libisoburn on ArchLinux)`
|
|
* gcc for 32bits (e.g. gcc-multilib for ubuntu) >= 11
|
|
* sfdisk (util-linux)
|
|
|
|
# Run it
|
|
|
|
`make run`
|
|
|
|
or
|
|
|
|
`make fd.iso && qemu-system-x86_64 -cdrom fd.iso`
|
|
|
|
you can also test it
|
|
|
|
`make test`
|
|
|
|
# Debug
|
|
|
|
gdb could be launch with debug symbols using :
|
|
|
|
`make debug`
|
|
|
|
Serial log will be saved in the `serialOut` file.
|
|
|
|
Then you can check some matos specific commands or pretty printing with
|
|
|
|
`help user-defined`
|
|
`info pretty-printer` (Should contains matos_pretty_printers)
|
|
|
|
# Change Disk partitions
|
|
|
|
You can either modify the disk.sfdisk file
|
|
|
|
or
|
|
|
|
modify the disk image with your favorit tool (e.g. gparted) and re-generate disk.sfdisk
|
|
|
|
sfdisk -d > disk.sfdisk
|
|
|
|
# Multiboot
|
|
|
|
In arch/x86/boot, you can choose the assembly used to start the C part by removing the .opt extension
|
|
|
|
* boot.asm: intel syntax with multiboot support
|
|
* boot.S: GNU As syntax with multiboot support
|
|
* boot_multiboot2.S: GNU As syntax with multiboot2 support
|
|
|
|
/!\ multiboot2 is not supported by qemu for -kernel option (https://gitlab.com/qemu-project/qemu/-/issues/389).
|
|
So you may have to use the fd.iso image and modify the grub configuration from `multiboot /boot/kernel` to `multiboot2 /boot/kernel`
