Re: windows XP DOS Limited
Altough Windows (NT and above) command prompt isnt a "dos prompt", you can think that command prompt is similar to "Dos Protect Mode". So you cant change or even observe some registers and/or some storage arear, nor access directly I/O hardware.
The latest problem I have come up with is when I use examples in DOS , it locks up.
I read that XP DOS (the simulated DOS), does not allow you to manipulate register bits.
I advise you to try your ASM programs on a Dos environment. (MS-DOS)
