  • 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.

Interesting that CSM mode doesn't support RAID. I assume the speeds for drive 2 is just a result of the RAID level I'm using.

Why is it my system starts at 1 for the drive number? Everyone else seems to start at 80.

BTW, I had 2 of the Western Digital drives in this system, but was running out of room, so when I upgraded some drives in my NAS, I just put the old one in this system. That difference of 30 is noticeable on this system.

The "80's" are BIOS designations. When ReadSpeed starts up, it attempts to determine whether the BIOS is recognized any of the system's drives and assigned them BIOS drive numbers which, for hard drives, begin at '80'. Any drives that do not appear to be associated with the BIOS are numbered starting from '1'. It might be that your use of RAID has kept the BIOS from assigning drives. And you mentioned CSM, so that might also be part of what's going on.
 
My system boots into Windows with UEFI. The other thread with the list of boot menu keys allowed me to not have to change that just to boot into ReadSpeed. When I tried to use Spinrite on this system, I had to do the following:
  1. Turn off the RAID
  2. Turn boot mode to BIOS (Option is hidden with RAID turned on)
  3. Select drive I want to boot from
  4. Once I wanted to go back to Windows, reset the boot order, and turn on RAID (which in turn switches the system back to UEFI)
