If Paul did say that, he's wrong. The _Master_ boot record is on hda - the
first sector.
To see what's on your system, as root do this:
for d in a{,1,2,2,4}; do dd if=/dev/hd$d count=1 bs=512 ; done | xxd | less
This will take the first sector from each of the five volumes and write them
as a single stream to output when then is processed by xxd an less.
Each sector is 200 hex long:
00001f0: 0000 0000 0000 0000 0000 0000 0000 55aa ..............U.
0000200: 0000 0000 0000 0000 0000 0000 0000 0000 ................
the first of these is the last part of hda, the second the first of hda1.
