This kind of GUI

[mohdumar]

just installing RedHat 9 from 2003. Wonder how do they get this kind of GUI at boot after loading kernel:



This can be also seen in XP installer, is there a way for it in a custom OS?

Just implement it yourself. It's too simple to waste time and find out whose code you can steal.

You need a print function, that can also change foreground and background color.

Then you use extended ascii, for borders etc.
Simple example

Code: Select all

WinEdit:  db 'ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿',13,10
	     db '³ Cut     Ctrl+X ³',13,10
	     db '³ Copy    Ctrl+C ³',13,10
	     db '³ Paste   Ctrl+V ³',13,10
	     db '³ Clear   Del    ³',13,10
	     db 'ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ',13,10

You would then have functions to move and print the highlight bar etc.
You can add shadows by changing the back/fore ground colors, that the shadows would overlay.

Use a bit of ANSI escape codes in your strings and print functions.

and then you can do cool things like this...
