	Right.

	First of all, thnx for replying. :)
	It won't work. I always get the same trash. This is even more strange!
Always the same numbers!
	My old code (16 bits) was:

#define MASK 0xFFFFFFFL
#define BASEADD 0xD0000000L

	for(counter = foo; counter < foo2; counter++)
	data[counter] = MASK & *(BASEADD + counter);

where data[] is float.

	It is important to say that when I use sel =
__dpmi_segment_to_descriptor(0xD000 + counter); I DO get the right data,
but not one by one (of course, cause counter should be the offset). Or,
in other words, the data IS there.
	Sorry to post it again, but it is the very last thing I got to do to
finish the project.
