  • DNS Benchmark v2 Release 5 with Consultant License
    Guest:
    If you own any earlier release of our DNS Benchmark you may immediately download its release #5 replacement. Running an earlier release will detect the new release and help you upgrade.

    Although this release is cosmetic, appearance matters and affects ease of use. The biggest change, as seen in the image above, is that the DNS Benchmark now has a traditional Windows application menu to more fully expose its many features. This release is also "Consultant License Aware" and GRC will now issue a Consultant version when owners have previously purchased four "Personal Use" licenses. If you have previously purchased four DNSB licenses, or if you wish to upgrade your "Personal Use" license to Consultant, GRC's purchase process will direct you through that process.

  • 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?
