resize bochs vga screen

[steven765]

I can't seem to get the vga options to display qutie right:

Code: Select all

	## Set video mode to 80x25 for basic console.
	movw $0x1202, %ax  #set the scan rate to 400
	mov $0x30, %bl
	int $0x10
	mov $3,%ax              # Video mode 80x25x16
	int $0x10               # Interrupt (set video mode)
	mov $0x1104,%ax         # smaller text =  more lines
	mov $0,%bx              # 
	int $0x10               # Interrupt (set video mode)
	mov $0x1003,%ax         # Toggle blinking
	int $0x10               # Interrupt (set video mode)

If i make the smaller text line = 1112, the text is squished and fits on screen, but if i try the larger character set in the code above the lines just scroll out of view and if you hit return enough the terminal appears. So it's there, I just can't seem to find the correct command to tell bochs to resize the window.

That's because you never change the resolution because the height is already 400 for mode 3, you're only changing the font. Use different AH=0x00 or AH=0x4F calls to get the resolution you want.
