  • SpinRite v6.1 Release #3
    Guest:
    The 3rd release of SpinRite v6.1 is published and may be obtained by all SpinRite v6.0 owners at the SpinRite v6.1 Pre-Release page. (SpinRite will shortly be officially updated to v6.1 so this page will be renamed.) The primary new feature, and the reason for this release, was the discovery of memory problems in some systems that were affecting SpinRite's operation. So SpinRite now incorporates a built-in test of the system's memory. For the full story, please see this page in the "Pre-Release Announcements & Feedback" forum.

  • 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.)

I heard of this years ago and somewhat forgot about it. It looks like there is a cloud version now. I wonder if trying to design a CPU would help for understanding? I searched for CPU and it is like there is per-made CPUs designs. The is one problem however, I have started to use configurations that are not connected to the internet more and more. That means most of the software I buy needs to be able to run while not connected to the internet. I think this company has a version that will run on the OS, but I think it costs a lot. I am not sure if there is a version that is affordable and offline.

I guess a person has to almost waste time when time to learn these things because there is so much unknown.
 
If you want to focus on MASM style assembler there are good places on the internet for too!

I used the firefox extension "Down them all" to download all these samples from the MASM32 forums.
Am am thinking that some day I could study the code and maybe learn something.



With the growth of GitHub there are some things there too, I found these two users that have some stuff.
It would be nice if there were more on GitHub for assembler, studying others peoples code is a good way to learn I think.

I do know that someone on GitHub took the time to create the masm32 include files to program to the Windows API, this is something that sometimes assembler programmers have to do, converting from the C++ .h files I think. I could not file it quickly, so I am not sure of the address, but it is on there some place.

In fact, Steve has a download that might be helpful:


I downloaded that a few years time ago and studied some of it, if I remember correctly it has some of the marcos he talked about on the podcast, like the "free" macro are in there.
 
Ok, I have 80x86 Assembly Language and Computer Architecture, I disabled the DRM and I have speechify for the next year to read it to me. How could this possibly go wrong? If this works, I will do the same with the Irvine book and then maybe Jeff Duntemann's linux assembly book. It is easier to do Linux assembly now because of WSL anyhow.
 
Well I did this today to make it more easy and convenient to program in 16bit DOS ASM, setting up this stuff take a long time. If anyone has any question about how I did this, let me know. (the preview makes it look like I am playing doom, but that is not the what the video is about, I was just showing that FreeDOS has sound over remote desktop).
