Choose-OS is a alternative, easy, fully configurable boot loader for Linux/PC with a boot menu.
It is a program which, when you boot your computer, allows you to select the operating system to boot.
Linux, DOS and other operating systems are supported.
It does the same stuff that LILO or OS/2 boot manager do (offering a simple boot menu at bootup).
Choose-OS has some nice features not found in other programs of this kind.

Look and Coolness:
 * You can choose the colors used for each image separately
 * You can position the menu and timer or even each image separately on screen
 * Hotkey can be specified for each image
 * And finally, you can have a background image (plain ascii text or screendump format)!

Other stuff:
 * Emergency bootsector - If there`s been a failure loading Choose-OS mapfile or 2nd stage loader, an emergency bootsector will be tried to load, if one specified
 * Initrd,bzImage,MBR rewrite, hda/hdb and fd0/fd1 swapping, etc.
 * Single-shot autoboot
 * dosmenukey -option.
 * Includes X interface to configure the boot screen and all parameters

THIS IS BETA-STAGE SOFTWARE AND YOU ARE TRYING IT AT YOUR OWN RISK! YOU HAVE BEEN WARNED!

SHORT INFO

    Choose-OS is a boot loader (boot manager) for Linux/x86. What the
    program does is let you choose the operating system to boot.


WHAT IS NEW?

    0.9:
        - Complete rewrite
        - More configurable
        - Some options can now be given at boot time
        - Modular user interface support
        - User interfaces support sub-menus
        - More bloated than the old one :-)

INSTALLATION

    To build and install the program:

        cd sources
        joe makedef.in  # (to change compilation options if needed)
        ./build.sh      # or: ./cfg.sh && make depend && make
        make install    # (as root). 

        - If you have a previous installation of chos, it might
          be wise to 'cp /sbin/chos /sbin/chos.old' before running
          'make install'. It should not overwrite other chos stuff
          (modules are now located in /boot/chos-).

        - When recompiling chos, running 'make realclean' is a good
          thing to do before repeating the above steps

    To install and configure the loader:

        - Backing up any important data is *highly* recommended.

        - Create a configuration file (see the following section).

        - It might be wise to install chos on a FLOPPY for the first
          time to see if it is willing to boot at all and then, if it
          works, try to install it on a hd. When installing this way and
          you have been running a previous version of chos, have chos
          use mapfile other than /boot/chos.map.

        - Run the installer: chos [--verbose] [other options].
          For a list of options, run: chos --help.

        - If everything was successfull, chos should be installed
          now. Good luck with the next boot.

    NOTICE:

        Many distributions seem to contain a non-working version of as86
        (0.4). This version  should work at least.
        (If you know an "official" site for the package, please let me know.
        I am not going to waste my holiday searching for it).


CONFIGURATION

    See the files under docs/:

        configuration.txt       General configuration
        ui.txt                  General help on user interfaces
        ui-*.txt                Help on configuring user interfaces
        loader-*.txt            Help on options for loaders

    There is still much work to be done with the documentation
    but it is not on top of my priority list.

    For help on command line options, run:   chos --help

Contacts

I would appreciate any feedback from users of chos. I am mostly interested in bugs (crashes, hangings, etc.), but of course success stories are welcome as well. The recommended way to get support and contact me (Arnold Shade - current maintainer) is to use "Help and support" forum on sourceforge project web-site. However you can use e-mail addresses below to contact authors directly. There are no hypertext references in the e-mail addresses below due to spam bots protection:

Current maintainer of chos is Arnold Shade (what is a nickname due to several reasons being anonymous). Use it to refer chos 1.91 and above.

Special thanks to Don Mahurin who found chos and initially created chos project pages on SourceForge.

The original author of chos is Tuomo Valkonen. Use it to refer chos 1.9 and below:

Note: you need to replace " __dot__ " with "." and " __at__ " with "@" before using the addresses above.
