    Does anyone know of a linux or BSD based distro that will install on an old Palm Pilot? Not the III or V lines, the original lines. I've got one just sitting around. I've already got a replacement for it I just want to play around with it. Does anyone have any links for instructions on installing Linux (or any other OS) on them?

      Well, there's palm linux (palm-linux.sourceforge.net). Doesn't work on my m100, dunno about the older Palms.
      • It seems like there's a higher compatability with earlier models. Most of the Palms listed as working on the proget's site use DragonballEZ processors (IIIx and later) although they do mention a modified Palm Pro (Dragonball processor) working. If nothing else, you should be able to slap a Palm Pro or Palm III upgrade card in and give it a whirl. It's not exactly standard hardware, but I'm sure the project would apreciate some feedback on if it works.

      Check out Embedded Linux/Microcontoller project [uclinux.org] I've never tried it personally, but looks promissing. Don't know about support for the older platforms you're talking about though. Gives you somewhere to start though.

      Some very usefull tools that I've used on newer Palm devices with net connectivity:
      Top Gun SSH [www.ai] - Works pretty good for remote shell access.
      PalmVNC [btinternet.co.uk] - Decent VNC implementation for the Palm.

      Not *nix on the Palm, but gives you good access to remote systems.

    Palmtop NetBSD
    by Michael Lucas
    06/05/2003

    In my previous article, I discussed building the latest NetBSD-current and installing it on your system. Today, we take things a little further and use NetBSD's cross-building abilities as a tool to install it on a rather unusual platform â" specifically, the HP Jornada 728 palmtop, which comes with Windows CE (WinCE) embedded. While HP no longer makes this device, you can pick them up used or on auction sites. The process discussed here uses examples from the Jornada 728, but with some tweaking will work on many other types of hardware. You could even install onto standard PC hardware in this manner, if you wanted to be masochistic about it.

    Setup
    This method requires that you already have a NetBSD machine that can physically accept the disk device you want to install onto, and that has the same sort of disklabel(8) as the Jornada, which means that you need the same endian hardware. You're probably best off running standard X86 hardware for this type of installation on this type of palmtop. In this example, I use a Toshiba laptop running NetBSD-current 1.6P to install NetBSD-current 1.6P on my Jornada. I'm using a 512MB flash card to run NetBSD, and am using a PCMCIA adapter to attach the flash card to the laptop during the installation phase. If you're using a desktop, you could use a USB-to-Flash adapter.

    Running NetBSD on your Jornada will erase all data from the WinCE operating system. That's OK, because you'll never boot back to Windows once you discover the joys of palmtop UNIX, right? Still, you might want the WinCE data some day, so be certain to back up your device before starting this install! Some people who switch boots between WinCE and NetBSD use the backup tool that comes with WinCE to back up their data to the FAT partition on their flash card. If you do this, be sure to use only the backup tool that came with the Jornada, not a newer version.

    NetBSD runs on a whole bunch of hardware that was never intended to run UNIX, so this install isn't really anything special. Each of these unusual platforms has its own unique requirements, which are generally documented on the appropriate port page for that architecture. Check the port page for an instructions document, which in this case is the Using NetBSD/hpcarm page. The directions may be partially obsolete, as code development frequently outpaces the web documentation. Still, it's a good place to start. Also search the mailing list archives for your chosen platform for other people's experiences installing and running NetBSD on that system. Lastly, you'll want to be certain that NetBSD runs on your system â" for example, while the Jornada 720 and 728 are well-supported, the Jornada 820 isn't yet.

    Bootstrapping
    The how-to-use page for hpcarm shows that you need a kernel and a boot loader that runs in the WinCE environment. At this time the page also mentions a root filesystem image, which is not yet available. The only piece you really need to get at this point is the hpcarm boot loader, which is available as a uuencoded file in the NetBSD source tree at /usr/src/sys/arch/hpc/stand/binary/ARM/hpcboot.exe .uu. If you have trouble with uudecode, Google led me to a variety of places from which it could be downloaded. Get the boot loader hpcboot.exe and save it for later. Don't worry about the kernel linked from that page; we'll build our own kernel.

    Now go to your existing NetBSD system. We covered the basics of building NetBSD in the last article, including getting the source code and using the build.sh building system. As each platform has its own compiler requirements, make(1), and so on, we need to start by building these tools for the hpcarm architecture. Here, we use the -T flag to specify where to put these tools, and the -m flag to specify the type of machine for which you're building.

    # cd /usr/src
    # ./build.sh -m hpcarm -T /

              Not really. Bear in mind that this was in the late 1970's, and 64KB wasn't a really tiny memory footprint. All I'd done was get it to run in 32KB less than what was, as I remember, the stated minimum memory requirement for V6 - 96KB. If you had a 96KB PDP-11, you had enough memory to run V6 and compile stuff.

    People have done similar installations on Windows CE devices for awhile. For example, I run NetBSD 1.6 on my IBM z50, also with a 512MB Compact Flash card. The only difference is that this installation was done entirely from a NetBSD mothership while I installed from a FreeBSD ftp server I set up.

    See, this is the thing I've never understood - why would you install *nix/BSD on a palmtop? Most of the apps out there are not designed for such a small screen - I've experienced the pain of XWindows on a 640x480 screen - And there's such a huge base of apps out there already. Mind you, I prefer the Palm OS over WinCE, and 99% of what I want / need in a PDA is already available.

    I can't see the benefits of this. In my mind, it's like tearing out the upholstery of your car, and replacing it with gravel. Sure, the car's still usable, but it's not comfortable to use, and it looks like crap.

      why would you install *nix/BSD on a palmtop?

      For similar reasons that my company installs it on haldheld devices I guess. We run a minimal installation, including X, and write apps using the fltk toolkit. OK, you're not going to run OpenOffice or Mozilla on the things, but for specialised applications (warehouse management in our case), they work well. And it's a damned sight nicer programming a NetBSD app than a Windows CE one (the handhelds come preloaded with WinCE).

      Because *some* of the apps are designed for such a small screen. Also, if you had the skill to port UNIX to the PDA then you probably have the skill to code up the apps you need as well.

I've installed on a 1 Gig disk before (with X), so 512 megs are not so bad, if you forget about X. What would you need for work? Email, perhaps some sort of instant messaging capabilities, ability to take notes, etc... personally, I'd rather not be bothered all the time with pages and so forth, but if you have to do it, might as well make it easier on yourself.
