Okay, so OSI(Linux) sounds like a NOP from what you can see on this box.

I don't think you need to.  Just speak up if it fails
when you do get to it.

Everything I said about the Dell Vostro 1000 is true of
the Toshiba Satellite A100 -- the ASL is very similar.

"Like others, Dell Vostro 1000 sets LINX, but never checks it.

TPOS and OSTB are also affected, but in the ASL they're referened
only with comparisons > 4, (NT or greater) so OSI(Linux) shouldn't
have any effect there either.

That leaves the return value of OSTP(), which I see invoked
in several places, but the return value is never used.

So I'll add this box to the OSI(Linux) NOP list."

The Toshiba has some additional references to these names
that the Dell doesn't have, but he conclusion is the same.
.

BTW. if you can disable HTML format and reply in plain text,
that would be helpful.
