Russ,
So I did get 4th edition running on my target PC. In my case I just let
Plan9 have the rest of the disk, instead of having another partition behind
it. I did run a utility on the disk which reports that the Cylinder value
used presumably calculated and set from Plan9 was wrong. My tool said that
the number of cylinders should be 2481, while the value written in was 1023.
I haven't looked into the code to see if this was the problem or not, but I
suspect it could contribute if I really tried to use an adjacent partition.
I've included the disk information below.
Regards,
Richard W.
