Minix for the HP200LX

MINIX can be run on the HP200LX palmtop using the dosminix "file as disk" file system. Mack Baggette modified the minix kernel so that it will work with the LX's eccentricities. There is now access to the LX's dos drives, and work on the serial port is progressing. PCMCIA support is still lacking.


Download

The following packages are based on Mack's final release of minix. The first one is the original file, with each one after a modification of the preceding one, as described.

LX Utilities

I'm working on a few utilities for the LX. These should all be considered beta versions right now. Catd in particular is unstable, at least when writing to a flash card, and will lockup the palmtop frequently. I believe it is a problem with speed of writing. Writing to the built-in C: drive so far has worked ok. Writing to the flash card will sometimes work. Running it on a laptop, and writing to the flash card also works without problem.

Installation
  1. Download lxutil.zip.
  2. Unzip to the directory which contains your dosminix file. This will create a 64k file called lxutil.mnx which is a small dosminix file system.
  3. Boot minix, but instead of pressing = at the prompt, hit the escape key to enter the monitor.
  4. Type in 'dosd5=lxutil.mnx' without the quotes, and press enter.
  5. Type 'boot' and press enter to start minix.
  6. Login as root, and at the prompt enter 'mount /dev/dosd6 /mnt' to mount the new partition. Yes, that should be a 6, not a 5.
  7. Now you will find the utilities and a README file in the /mnt directory. The README will explain installing the files to your command directories and has a little more information on each command.
  8. After installing the utilities, the lxutil.mnx file is no longer needed. It's only purpose was to transfer the files, and does not need to be mounted the next time you run minix.
