  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

Those of you who were testing in the earlier days would remember an incarnation of freeDOS that was titled SpinDOS.

It had a few extra features such as power commands which I feel might be useful especially for those of us who are using Zimaboards with no power buttons.

Is it worth merging the two together?

I'm not recalling things the way you are, @DarkwinX.

To the best of my recollection, “SpinDOS” was never more than my tweaking FreeDOS to be tolerant of non-FAT formatted drives and partitions. There was some of that early on, but I added more a few months ago.

There is a FreeDOS command “fdapm” (which stands for FreeDOS Advanced Power Management) that comes in quite handy when it's combined with a few "aliased" command shortcuts. For example, my autoexec.bat files always contain:

alias reboot=fdapm warmboot
alias shutdown=fdapm poweroff
alias off=fdapm poweroff
(I also have...)
alias eda=edit c:\autoexec.bat
alias edc=edit c:\config.sys

So, this allows me to perform a reboot with the command "reboot" or to power off the machine with the command "off". And if I want to edit the autoexec.bat file, the command "eda" does that. :)
 
I guess I remembered it being more than the Blue themed DOS. I tried to spin it up again to see if there was anything else but I could not get it to load.

Oh well!

For those looking to add fpadm to their GRCDOS USB you can grab it from the FreeDOS archive GitLab
