I have always recommended using the largest possible size for the 
bootcode partition, 512K.  There is no reason to go with a smaller size, 
the space savings are insignificant.  It is safe to guess that bootcode 
will never get smaller.

I also recommend starting the first real partition at 1M.  This also is 
frequently ignored.

Here are my instructions:

The wiki should be updated.  Better yet, that section should be removed 
and the corrected procedure shown in the Handbook.
