[Diy_efi] ALDL interface design(did some changes)

[mark krawczuk]

hi,   when i built me aldl interface, i had problems getting  it going.
 it  might have been a combination of problems,   but i think  it might have
been the os.
i used the same laptop, and   use  w98, no go, then i put on  w2k and it
worked fine.
maybe play around  with different os`s ??
