linux-0.11
A slightly modeified version of linux-0.11 that can be built with gcc 5/6/7/8 series.
Usage
To run the kernel, you should install the packages by the following instruction(on Ubuntu):
sudo apt install build-essential gcc-multilib bin86 as86 bochs bochs-x
Then prepare the work space:
./run.sh init
And build the kernel:
make
To boot the kernel, type:
./run.sh
Notes for Ubuntu 22.04 and later
Ubuntu 22.04 and later has removed as86 as a sperate package, so you should install the package bin86 instead. The full command is:
sudo apt install build-essential gcc-multilib bin86 bochs bochs-x
bochs on Ubuntu 22.04 and later has a bug in the latest BIOS, so you should use the legacy BIOS instead. To do this, you should modify the file bochs/bochsrc.bxrc and change the line:
romimage: file=/usr/share/bochs/BIOS-bochs-latest
to
romimage: file=/usr/share/bochs/BIOS-bochs-legacy
Then the kernel can be booted as expected.
