  • 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.)

This laptop uses AMI UEFI. I enabled CSM and Legacy boot options. When I boot it to my InitDisk flash drive, the screen stays black. It booted successfully though, because when I do things like ECHO HELLO > CHUWI.TXT, that file gets created. I tried running MODE 80, but nothing happened. Legacy USB support is enabled by default.

This thing has hundreds of UEFI settings I can tweak, many of which cause it to no longer POST. I've had to pull the battery a few times. One of the options that breaks it is the Video Option ROM. It defaults to UEFI, and changing it to Legacy completely disables video output (can't even get back into the UEFI menu). Am I correct in assuming that this is the critical setting that's keeping me from getting video output in FreeDOS, or could it be one of the other settings?

I've tried running SpinRite, but the screen stays blank, and no log is created. The most I've gotten is an empty DBG file with PR506 DIAGS VIDEO AUTO EXIT LEVEL 1 NEVER TYPE AHCI #0 #0.
