09/05/2010 We have been working on a new kernel base for the HD2 for few days now. Markinus started the initiative by introducing our present HD2 specific changes in the EVO4G release kernel source code. Right now the htc-msm-2.6.32 branch is still more advanced. We might create an autobuild for the EVO4G base kernel in case it will be superior at some point.
*None of the current releases will touch your internal flash. After restart you are back in the usual winmo.
*When Linux is booted, windoes mobile is shutdown abruptly. Although this is very rare it can cause some data loss. Please save your work and make frequent backups!
*You need at least a 2.08 radio rom version installed on your HD2. If yu have an older version you might not be able to boot Linux.
For updating purposes and 'rom' creation
Automatically compiled Linux kernel builds for the HTC HD2 from GIT source code.

Most recent zImage (Linux kernel image)
The Linux kernel is the core element of your operating system. It contains most of the drivers. It is supplied in form of a compressed (gzipped) executable binary Image. Along with an initial rootfilesystem aka initrd it is loaded into memory and executed by the bootlaoder HaRET.
Most recent Linux kernel modules to match zImage-htcleo-latest (has bcm4329.ko)
Kernel modules are drivers that are not included in the zImage. They go seperately in .ko files. bcm4329.ko holds the wifi driver and tun.ko is needed for tunneling. For android use you must extract the modules.tgz file, search for the .ko files you need and copy them into /system/lib/modules/ directory. See FAQ for how to copy files into your android install.
The haret bootloader is used to start Linux according to the instructions it reads from the file default.txt . If HaRET sees a file called startup.txt it will use this instead and boot Linux directly without any prompt.
startup.txt (bootloader/HaRET configuration - auto updated to match latest GIT kernel)
NOTE: This example configuration only holds the parameters critical to booting with latest GIT. Ask the person supplying you with 'roms' for additional parameters needed. See FAQ section for more detail on parameters.
Please browse the main HD2 Android forum for various recent builds.
It is always important to install a recent kernel. See post #3 for how to.
