Thanks for the link, Wonko. I see that the source for Wait4UFD 1.0.1 is in there. I also see that Wait4UFD doesn't have any UFD-specific code inside, but uses almost the same logic as Michael Brown does for booting from SANs, which is nice. I'm a bit lost as to what would make it magical for UFDs where WaitBt would fail.
I am suspecting that both thingies work just fine (though through different means/logics) and that mazak000's results comes out of *somehow* the way he installed (or failed to install ) the WaitBt driver.
But that is only a "gut feeling", nothing more.
On the other hand IF WaitBt worked fine for tal.aloni, why would he had rewritten the newish driver?
I guess we have to wait for some more details from him. (besides - again - the installing issues).
From the outside - however - it seems like the *whatever* logic you used in WaitBt is *somehow*/*somewhat* overkill IF a "simpler" logic is as well delivering the same result. <- both thingies should IMHO go through an Occam's Razor to see which one provides the simpler solution...
