  • DNS Benchmark v2 is Finished and Available!
    Guest:
    That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.
    /Steve.

  • 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.

    (You may permanently close this reminder with the 'X' in the upper right.)

Greetings all and Happy New Years Eve -

Was hopeful that someone can point me in the right direction. I use an iMac for my daily driver, which has macOS Catalina on it.

I downloaded the ReadSpeed files that were specific to Mac and then used BalenaEtcher to create what I thought was going to be a bootable USB. When I restart Mac by holding down option key to select an alternate boot device, the ReadSpeed USB is not there.

When I look at the file on the USB, it shows 2 of them PCI.EXE and RS.EXE

Any help is appreciated.

Thanks
Jay
 
Hey Jay. There are a number of DOS-specific hidden files that you won't see in the Mac Finder. Just restart your Mac, and hold down the Option key once you hear the startup chime. You'll get a list of bootable images, just arrow over to the one labeled Windows.

If that doesn't work, this is an excellent article about booting a Mac into DOS:

It seems people have been finding that Macs that used to boot Windows off USB will no longer do so. This may or may not be tied exclusively to Big Sur and/or the new Apple notarization feature (signing apps.) Don't be surprised if you have trouble or even the inability to get it to work.

How old/new is your iMac?
Does it have a cd/dvd player?
