    Please see the BootAble page at GRC for the whole story.
  • 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.

Just a heads up for people interested in security to try NextDNS. Its Pi Hole in the cloud. The service is free up to a point and offers 3 advantages:

1. DNS calls are encrypted using either DoH or DoT whatever is supported by the software you are using
2. No ads
3. No tracking

It can optionally log DNS too which comes in handy for auditing purposes. You can write your own blog about what your phone/computer is doing at night while you are sleeping. Like I did

Any DNS service that does blocking will make mistakes. NextDNS offers both white lists and blacklists to fix those mistakes. For the techies amongst us, I suggest you get friends and family using a Chromebook configured with NextDNS. ChromeOS version 87, released earlier this month, just added NextDNS as a Secure DNS option.

On a related note, I have a list of assorted live DNS "testers" that can be used to verify the DNS servers currently in use.
Be aware that different browsers on the same system can be using different DNS servers.

My only relationship with NextDNS is that of a customer.
NextDNS is pretty cool, it's free up to 300'000 queries per month and then $2 for more.
It seems linked to one IP, I was using two IPs with OpenDNS but it stopped being as good when I switched to an ISP with CG-NAT.

I blackhole certain DNS servers with static routes on my network as my teenager is motivated to beat my controls. I like NextDNS, I have to say that.
