CHAPTER 4. LIVERAM DISKS 4.4. HARD VERSIONS

4.4.2.2 The Outﬁle

There is nothing to say about the outﬁle, except that giving it a representative name is a nice thing.

For this, you may use the script given at point 4.4.2.7, p. 13.

4.4.2.3 HaRET

The HaRET bootloader is already an old thing: it was also used in Familiar. The latest one

haret-0.5.2.exe.

4.4.2.4 zImage

The easiest thing is to use the Narcissus image generator

from

Angstr

om’s website. It will generate

a ﬁle like

hx4700-full-x11-image-hx4700.tar.bz2

for the

hx4700

. You then go to its folder

named

boot

, and extract the corresponding zImage. For example, it is here

zImage-2.6.21-hh20

Its numbering is the kernel’s numbering, as the zImage is the kernel.

4.4.2.5 Initrd

The

initrd

ﬁle is under the form of a

.cpio.gz

. For example, its current name is

initramfs.cpio.gz

You can use the following bash script to make the initrd (thanks to Lex Landa for this):

#!/bin/sh

# Execute this from the initrd root dir.

find . | cpio -o -H newc | gzip -9 > ../initramfs.cpio.gz

4.4.2.6 The Startup Script

You can use the following startup script:

# initramfs-bootmenu HaRET script

msgbox "Attention!" "This will boot Linux. All memory will be overwritten and hard reset will be

required to return to Windows Mobile.

You *MUST BACKUP* your data first. Continue booting (Cancel - quit to make backup)?" 0x40031

if result == 2 exit

set cmdline "root=/dev/ram0 rootdelay=3

ip=192.168.2.202:192.168.2.200:192.168.2.200:255.255.255.0:ipaq:usb0

console=tty0 console=ttyS0,115200n8 rdinit=/sbin/init"

ramboot

It is named startup.txt.bootimage in our example.

4.4.2.7 Automatizing The Task

If you want to make the task of producing the bootbundle more automatic, you can use the following

bash script (thanks to Lex Landa for this):

Which can be found in the http://handhelds.org/

koconnor/haret/ directory.

That you can ﬁnd at http://www.angstrom-distribution.org/narcissus/.

The name of this ﬁle has actually be decided only by me, but it represents the content of it.
