This is not completely the same: in my code was no "nBytesRead" - BC
for such simple variables usually generates extra code to save AX on stack.
:( Also, I think, "!=" is more precise (and safe! - no issues with
signed/unsigned comparisions) condition, than "<".
PS: Bart, please, explain, why kernel returns nonzero root_entries filed in
current BPB32 (whereas both default BPB and boot record contain zero in this
field)?
