[rescue] Ultra 30 and Maximum Drive Size

[Gary Nichols]

Here's the partition layout of the boot drive:
partition> print
Current partition table (original):
Total disk cylinders available: 8152 + 2 (reserved cylinders)

Part      Tag    Flag     Cylinders        Size            Blocks
  0       root    wm     240 - 1422        2.47GB    (1183/0/0)  
5181540
  1       swap    wu       0 -  239      513.28MB    (240/0/0)   
1051200
  2     backup    wm       0 - 8151       17.03GB    (8152/0/0) 
35705760
  3 unassigned    wm       0               0         (0/0/0)

  4 unassigned    wm       0               0         (0/0/0)           
0
  5 unassigned    wm       0               0         (0/0/0)           
0
  6        tmp    wm    1423 - 1662      513.28MB    (240/0/0)   
1051200
  7        var    wm    1663 - 8151       13.55GB    (6489/0/0) 
28421820

Also, a minor correction to my original post (I type o'd) the error 
message stated it was booting off of :b, and it should have been :a.

Do the 64-bit machines still have the 2GB barrier?
