How do you load your loaderIt is a disk. Put the disk in and turn on the computer.

Is it just a single binary fileIt is. The applications are then run off of the second disk.
also single files.

so far?lol, it works. That's a good start

I'm having many issues with VESA, very complicated imo.

Don't forget... many people steal from you when it's public. This has become a real problem.

How do you load your loader without a file system? Is it just a single binary file so far?

When I rewrite it in assembler, it will use BIOS calls, not DOS calls. Only reason it was written for DOS was because at the time I was using MSVCQuoteQuotewindowing systemThis is where i am at... I am currently experimenting with display modes.
I only found my code a few days ago. I aimed to be VGA compatible, and used 800x600 mode. I forget exactly which mode though, I need to read my code thoroughly. Good thing all my code is heavily commented

« Last post by Structure on January 22, 2020, 12:46:05 AM »I have an IDE as well... Which is a collection of .exe tools for windows.
example.aro:
This can be assembled as a .img and run from the bootLoader.
Step 1 cmd: arrow example
Step 2 cmd: nasm example.asm -o example.img
There are some files that are automatically included to construct the proper structure to run on the OS. It currently requires an immutable directory structure as well, which will change eventually with maybe a settings.ini ? idk.
I considered writing a development environment in the OS, but it makes no sense to me. It makes more sense to use the power of windows and create the binary's. As far as the file system, this is trivial imo. As long as the disks run, organizing them on the hard drive is simple.
To run a disk you just push F5 at the command prompt.
After the application runs it returns to video mode 0x03 and the command prompt.
example.aro:
Code: [Select]
<print.asm>
string: db "hello world", 0
__entry:
print string

« Last post by debs3759 on January 21, 2020, 11:59:26 PM »I never got beyond writing a FAT12 boot sector (it could load and pass control to a 16-bit binary in the root directory, with any amount of fragmentation) and a CPUID app that can detect anything from 808x up to the first 64-bit CPUs. Then my poor health got in the way. I hope to resume coding this year - health hasn't improved, but has stabilised. I did plan to write a simple 32-bit OS that can detect and initialise a wide range of hardware, and I hope to at least get that underway. Might write a DOS based IDE in nasm, and convert my windowing code to nasm as well (in MSVC 1.52, I wrote a windowing system for DOS that could load 1024 child windows and switch between them, I forget how much memory it needed, but it could work on a 386 at a usable speed).

... unfortunately... my computer crashed about two years ago and I didn't have a recent backup...
If you search this forum for "Zulfi" you will find a few topics from "Zulfi Kahn". He started out with A Tasm bootloader I helped him convert to Nasm. I thought it sounded like "homework" and it was - he was the instructor. I worked it up into the rudimentary beginning of an "OS". Just a couple of commands. I realized, somewhere along the line, that I didn't know where I was going. How was my OS going to be better than Linux? Even better than 'doze? I didn't know... and that's where I quit. The little I had probably wouldn't help you much but you might have been interested in looking at it. But an IDE drive won't even plug in to a modern computer so I'm pretty much "out of business".
osdev.org and news:alt.os.developement have info on this topic... They'll tell you to read, read read before you write a line of code...
Best,
Frank
