Brief information... how does it work:

Reseting the video mode to mode 3 (mode 0 not supported by all cards)
Trying to set the video modes from 0 to 127 (MOV AH,0 | INT 10H)
Reading the cursor size to check a graphics mode was set (MOV AH,3 | INT 10H)
Getting VESA mode information of the current video mode (MOV AX,4F01H | INT 10H)
Searching for the number of VESA mode which has same properties (MOV AX,4F00H | INT 10H)

short mode number
width in pixels
height in pixels
number of bits per pixel
bytes per scan line
vesa mode number
nice, i come back home and the tool is already finished =) setting via VGA and then inspecting via VESA is very elegant, sometimes the seemingly complicated things are really simple =) minor nagging, sometimes there are more modes than there are screen lines, but one can pipe the output to a textfile "xmodes.com > xmodes.txt" and then inspect it.

my first version had 229 bytes and was not at all optimized, so the size wasn't too hard on this one ;) it's rather the functionality which makes this great :)

anyway, i figured that my GT1030 and the GTX1050 share a lot of modes; where the modes match, the "secret" number is the same. Maybe some kind of assumption can be made for the 10xx series, or even across a broader range of NVIDIA cards?

The archive changed.
The new 1.1 version shows the secret mode numbers even when vesa mode info function not supported.
Amazing tool idea =)
