  • 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.

Low level driver reuse by Malware?

Hi Steve,

I was listening to the Risky Business podcast and the discussion turned to malware and specifically the reuse of code and drivers (particularly low level hardware drivers).

A though then struck that any low level hardware drivers developed for SR 7.0 might run the risk of reuse on Windows for nefarious purposes?

Without knowing how cross compatible RTOS and Windows code might be then I don't know if this could be a issue or not. You will probably know though.

Clearly the availability of a signed(?} kernel level driver which has access to storage media might not be the best idea ever 😉

I suspect this may be a non issue or you already have a cunning plan to avoid this but, just in case!

Kind Regards

This seems to be a worry about something that is impracticable to actually happen. "Living off the land" implies that code is already in place (in general) for use. Code for a different OS is unlikely to be in place in a running Windows OS. Additionally, OS software is coded in layers, and RTOS32 has a layer that makes it look partially like Windows, but the underlying parts are going to be very different, and incompatible. (The company could not have binary compatibility at all levels without actually using Microsoft code and thus getting sued.)
