grub

[Regnat Nikolaus <nregnat@gmx.de>]

I'm using grub (0.5.96.1.cvs20010530-6) and since a few days I get the 
following message while booting the system:

There are differences between the bootsector and it's backup.
Differences: (offset:original/backup)
28:3d/3f, 29:65/00, 30:9c/00, 71:44/00, 72:41/4f, 73:54/20, 74:45/4e,
75:4e/41, 76:20/4d, 77:20/45, 78:20/00, 79:20/00, 80:20/00, 81:20/00
Not automatically fixing this.


Booting continues after about 10 seconds.
I tried to reinstall grub, but the message's still there. What's the problem 
with grub? Does anyone know how to get rid of this?
