Interesting, video memory seems to be somehow inactive at startup under NTVDM, however it gets activated if you call the INT 10h somehow, for example adding this simple check:
Code: mov ah,0Fh int 10h cmp al,3 jne no_text_mode (which anyway is recommended when you do such access like above) at the beginning makes it work. |

Tomasz: i think it's quite logical behavior... for easier running of apps that doesn't make any output to screen
