  • 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.

First without parameters.

Code:
   NOTE: 2 faster SATA drives are attached to slower SATA links. You may add
         the /ident command-line option to display and identify the drives.

Note all drives are potentially addable to the main or other RAID volumes the drives 81
are in volume 0 as RAID 1 (Mirror).
Device 83 is an externally dismountable drive so a candidate for testing various drives
with Spinrite.
 
Code:
NOTE: 2 faster SATA drives are attached to slower SATA links. You may add
the /ident command-line option to display and identify the drives.

Code:
82 0:31:2 RAID 0104 00 8086 2826 3 7 < AHCI Cntrl > <6.0> 3.0 2.0TB
83 0:31:2 RAID 0104 00 8086 2826 5 7 < AHCI Cntrl > <6.0> 3.0 4.0TB

Those two drives could go faster, in theory, but I presume you don't have enough SATA6 ports...?
