Linux for h4100 - installing Linux to the ipaq h4150 (老树出新芽)

本文详细介绍了如何将Linux安装到HP iPAQ h4150手持设备上。首先需要备份设备内存及使用一张至少有64MB空闲空间的旧内存卡。接着创建必要的文件夹并放置特定文件。然后通过一系列步骤，包括运行HaRET程序，选择安装源和目标介质等，完成Linux系统的安装。

HP’s ipaq handhelds have been capable to “run” Linux long before ports for other platforms(e.g. Palm OS or Siemens SX1) began to emerge. However, somewhat running and running a productive Linux are two entirely different things - let’s see how the h4150 Linux port fares!

Step 1 - back up your PocketPC’s RAM
Installing Linux onto your ipaq flushes the RAM of the machine(Linux needs it to work). So, please back up all the data on your PocketPC before attempting any of the steps below! Your data WILL BE LOST!

Also, your memory card’s partition table will be modified seriously - so better use an old memory card(I used a 128MB MiniSD card) that has at least 64MB of memory free.

Step 2 - install the files
Create a folder /linux in the root folder of your memory card(NOT in the RAM or ipaq file store). Below that, create a folder /rescue. Then, put the following files into /linux/rescue(mirrored here(single zip archive) for your convinience):
custom.txt
gpe-image-v0.8.4-h4000-1.rootfs.tar.bz2
haret.exe
ramdisk-rescue-0.6.3-r361.rootfs.ext2.gz
startup.txt
zImage-2.6.16-hh7-h4000-20060920151019

After that, hardreset your ipaq h4150 to free up the RAM. Open Settings and allocate at least 50MB of program RAM.

Step 3 - run HaRET, load RamdiskRescue
Now, use File Manager to run Haret in /linux/rescue. The program will boot up Linux and will start RamdiskRescue. There, choose Install Linux and choose the source and target mediums(just choose the SD Card twice) with the 5way.

After having chosen the target medium, the ipaq should best be left alone for an hour or so, while cryptic messages like the ones in the picture below scroll over its screen. The ipaq will repartition the memory card and will unpack Linux files to the EXT2 partition it creates - this alone took an hour on our machine.
