DEX-OS 1.03

[jedld]

Greetings,

I have just released the binary and sources of dex-os 1.03 as well as a CVS system. I've included some fixes:

- keyboard mapping problems. (Can't confirm it 'till someone tells me it fixed though)
- Freeze in some bochs systems.
- improved FAT16/32 read-write support
- other fixes which I can't remember.

The updated disk image might not be available at the time of this post so you might have to download the 1.02 image or then release 1 image and then just overwrite kernel32.bin.

Thank you very much and more power to OS development:)

I have given it a test, but unfortunately, the keyboard issue remains the same. Sorry.

dex-os 1.032 has been released, I hope it fixes the keyboard issue once and for all. As usual, the source and binaries can be found at https://sourceforge.net/projects/dex-os/. Thanks.

works like a charm on my laptop.

ed.exe produces a page fault as soon as I enter the first char, when started.

after that, the system runs in a kind of recovery mode. Starting ed.exe then leads to at least the possibility to enter lines, columns and rows are counted. is this editor like vim or rather like ced? how does one save/read files?

All in all a nice system. 've noticed you have an extra process/thread as scheduler. does this have advantages - besides modularity *gg*

stay safe

PS: You will need to check the key-combos for console switching and sorta ... I just get signs, but no other action. Perhaps you've placed some crucial scancode-translations elsewhere in the keymap?

I have just released the floppy image distribution based on kernel release 1.033. Like 1.02, it contains a C compiler (tcc) and some games in /boot/games as well as a working version of the Netwide Free Assembler (nasm) in /boot/prog. The 1.033 release also fixes some more keyboard bugs.

beyond infinity, there is no scheduler process , maybe you are referring to the task manager(dex32_taskmanager) which can be accessed by pressing CTRL-ALT+F1.

Thanks.

[distantvoices]

yes, its the task manager I am referring to.

Your OS now works fine, the HOtkeys are working, ed.exe saves a file, if stopped with "ctrl - x" - do you already have signals working?

Stay safe & keep up the good work.

Hi

I tried it on my 386 machine and my 486 machine (the Am5x86 in this I've got working at 160MHz now!)

On the 486 machine it works great!! Well done! Although the floppy drive seemed slow for even a floppy drive!

On the 386 machine, after jumping to your kernel, I just get an elipsis in the top left hand corner of the screen, then it resets.

What are your system requirements.

I might have used a 486+ instruction or probably something in the FPU department. Does your 386 (wow, I find it rare to get hold of one of this things these days) have FPU support? or does a cpuid instruction ruin a 386?

About the poor floppy performance, yes I've noticed it for quire a long time, although in some newer floppy drives it works fast while in many others it works really slow....it's a good thing I have cache implementation or else it would have been unbearable. It is probably a flaw in my floppy driver and I'm checking it out.

First of all the cpuid instruction is only on Am5x86, Intel 486DX 4 100 and Intel Pentium (and compatible) CPUs or better. 386s and lesser 486s don't have it.

As for the FPU, yes my 386 machine does have a Cyrix FasMath (387 compatible but faster) FPU. BTW on 386s the FPU was is seperate chip).

hope this helps

I tested it, and now it works ;D
But it's a bit slow, but I ran it in bochs with a p2
But it sure looks great
