CHAPTER 4. LIVERAM DISKS 4.3. EASY VERSIONS

1. A boot loader ﬁnds the kernel image on the disk, loads it into memory, and starts it,

2. The kernel initializes the devices and its drivers,

3. The kernel mounts the root ﬁlesystem,

4. The kernel starts a program called init,

5. init sets the rest of the processes in motion,

6. The last processes that init starts as part of the boot sequence allow you to log in.

4.3 Easy Versions

The easy versions date back to the year 2007. A hx4700 version can be found

with the name

Angstrom-x11-image-liveramdisk-2007.12-hx4700.exe

You simply use such a ﬁle by launching it in the WM File Explorer. That is really straightforward.

4.4 Hard Versions

The hard versions are as up-to-date as you expect them to be, because you constitute them. After

having spoke with Lex Landa because of a WiFi problem, some info emerged from this thread

becoming increasingly big.

4.4.1 In Theory

To build this

exe

ﬁle, there is a Python script. It is called

make-bootbundle.py

. Its usage is described

by:

make-bootbundle.py -o <outfile> <path to haret.exe> <zImage> <initrd> <script>

Let’s describe these elements in their order:

1. make-bootbundle.py: the Python script.

2. <outfile>: the name of the ﬁle you will launch in the WM File Explorer.

3. <haret.exe>: the name of the HaRET bootloader.

4. <zImage>: the kernel.

5. <initrd>: the initrd.

6. <script>: the startup script.

To understand what they mean, you need some basic knowledge in Linux/UNIX systems which

will not be detailed here. That is a prerequisite.
