OK, all you hard drive experts out there!  Here are a couple of questions
about hard drives for you:

1.  Given: an original IBM AT, with an 11-entry drive table in ROM.  How
    possible is it to tell SETUP that NO hard drives are connected, and then 
    go and plug in a HD controller and a (supposedly) non-supported drive?
    Would the ROMs on the controller allow it to be used anyway?

2.  What would be the consequences of hooking up, say, a 150 meg ESDI drive 
    with 34 sectors/track and telling setup it is a type 9 drive?
    (Type 9 is 112 mb, 17 sectors/track)

    Would the drive operate at 112 meg, 17 s/t, or would it simply not work?

3.  I'm somewhat familiar with the ROM upgrade/patch argument. In case it
    isn't obvious, I'm wondering what the chances of avoiding both are!  Does
    anyone have any experience with big and/or odd HDs on such an AT?


I'd really appreciate any help anyone can give me!  Thanks!
