Hello dear group members,
Im new here. And need some help about read/write cd sectors one by one with use assembler.

I can read absolute sectors of cd with Int 2fh Ax=1508h, but can not write
with 2Fh, Ax=1509h.

I think (not sure) first step should be read device driver request header. 
According to my assembler documents, Int 21h, Ax=5d06h gets 
request header to the location DS:SI+38h.

Unfortunately it doesnt truely work.!

Can you please help me?
What protocol should be folowed?

Respectively
- Bob
