  • 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.

Wow. What a blast from the past. While I was in high school, I used Hazeltine 2000 terminals at the local college campus to log in to the GE-255 time-sharing system. They were so much faster than the ASR-33 TTY we used to dial in from the high school. This was in 1972.

The GE-255 system was impressive for the day. It had a terminal unit with 21 dial-in lines that occupied an entire wall in the computing center. There was a 3-ft. diameter hard-drive spindle with about a dozen platters, that ran a file system with maximum 6144 character files, so that was the maximum program size you could write in Dartmouth time-sharing BASIC, time-sharing FORTRAN, or time-sharing ALGOL. Using the CHAIN command, you could chain multiple program files together (sort of), and cheat the file size limitations.

I still have punched paper tape of my programs that I saved using the paper tape punch on the ASR-33 TTY.
