Dreckig uses a megalithic kernel, so everything is run in kernel mode for increased speed and security.

[JackScott]

Running everything in kernel mode for speed I can believe, but would you mind explaining the rationale behind it being more secure? It's just the opposite of what is usually the case (user mode being more secure and fault-tolerant).

[GAT]

I mean secure as in from viruses, as you can not install software. It also gives me more control over the quality of software for my OS, since you can't use outside software.

Is it in real or protected mode - I see it uses int 10h, so I suspect real, but just want to know out of curiosity
--Saw it was real mode in the tags - by the way, I have a solution to your backspace problem
add on line 402 - after enter check:

Code: Select all

cmp al, 0x08
je .backspace

And after loop, put this in

Code: Select all

.backspace:
   cmp cl, 0	; beginning of string?
   je .loop	; yes, ignore the key
 
   dec di
   mov byte [di], 0	; delete character
 
   mov ah, 0x0E
   mov al, 0x08
   int 10h		; backspace on the screen
 
   mov al, ' '
   int 10h		; blank character out
 
   mov al, 0x08
   int 10h		; backspace again
 
   jmp .loop	; go to the main loop

I kinda did, as the second line says - I was referring to the tags on it

And so does the wiki.

Your not making your entire Operating system with code from the wiki are you?

It is free to the public but, for learning purposes

[Unkn0wn1]

No, I'm not - FS code, raw binary execution, syscalls, cli, libraries (screen, math,string, kb etc. (hopefully basic crypto to come)) time/date with formatting

Need I say more?

[GAT]

Sweet!
It works!
Thanks, Unkn0wn1.
Do you want your name or screen name on the splash?

[Unkn0wn1]

My name, thanks

--Ben Jackson

Oh, and it works here, as well. Just tested it in Bochs. Only got round to it now as I've been working on something for FIND

Megalithic?!

Yes, as you barely listed anything. If all you say is done, i can give you credit as i believe you have started not to long ago.


But if your just listing, the "doing" won't be as easy as said If Done Right

Megalithic?!

Yes, a Megalithic Kernel. The idea is to use simplicity to increase speed.

[ACcurrent]

You said "increase speed" and "increase security". Now, it seems beyond me how you can do such a thing in a megalithic kernel. If you were to use an in-kernel interpreter the performance would be slower and if you were not using one you would risk security breeches as there is no memory protection in kernel mode so how is it you are increasing both?

[bluemoon]

Increase is a relative word. I guess he is comparing to his previous version?
Think about this, Windows 7 has increased performance (compares to Windows XP). Yet it is still bloated.
