Hi Folks,

I spent most of last week repeatedly converting an A21P and a T21 into 
wortless bricks and back, trying to find a way to get FreeBSD running on
them.  I distilled the death point to:

- Do the install (I've used both boot0 and  LILO, doesn't matter), it's 
  a brick - won't even get into the BIOS menu.
- Pull drive out and boot on my 600X.  Fire up fdisk and change it from 165
  to something else.  Do not touch MBR or anything else.
- Put drive back in (A21P and T21) and I can now get into the BIOS screens
  or actually boot via boot0 or LILO into Win2K.
- Put drive back in 600x, change back to 165, back in *21
- It is a brick.

So, while I don't know what IBM is doing with partition type 165, 
I am convinced it is a key to the boot lock-up problem for the 
T21 and A21P.  Now boot0 has grown from 1 to 2 sectors in length, 
maybe that's what "the story inside IBM" is trying to talk about - 
I don't know.  However, the above pattern was reproduced with LILO, 
independant of boot0, so I really don't think boot0 is related to 
the problem.

We have a couple of T20s' running FreeBSD, so this particular behavior 
seems to be related to changes for the *21 models.  The T20 guys are
never going to "upgrade" their BIOS after this mess.
