Hiya,

 I first read something about Adobe Publisher (full install) using a part
of track zero.  They directly write there, outside of O.S. processes, to
lock in their copy protection to a one machine installation.  Nice guys.
Later, I read that GRUB 2.0 is trying to use the same bytes.
 Last write wins.  :-(

> blindly overwriting hard disk content between the MBR and the first partition

  Yep. I've heard about it.  There've been some "work-arounds" talked about that
utilize Grub's MBR backup facility, backup-before and restore-after, the Windows boot.
This contains the damage and recovers the ability to boot to a Grub menu.
The Windows bootloader is not dynamic like Grub.  That is, Grub can interactively
change the MBR, on the fly, and needs no secondary program (lilo-install, fixmbr.exe).
The older Grub (prior to 1.0) stays in the first 512 bytes, and won't be affected.
Microsoft is stuck in the middle of this, and prolly won't do anything.

  Personally, I think if you give that much money to Adobe for an MS based program...
Good money after bad.  Use an Apple machine instead.

Subject: GRUB and 3rd Party software conflict
From: lthielster@gmail.com
To: plug-discuss@lists.plug.phoenix.az.us

Apparently both GRUB and some 3rd party Windows software make use of something called the "embedding area" of a hard disk and not standardized.  The result is apparently a possibility for both to use the same space and for that software to make GRUB unable to boot the system.

Be sure to read the comments to the Slashdot story.  With no standard governing use of that non-partitioned area of the disk, it is perhaps not surprising that is is not a good idea to depend on it.  Since I doubt the proprietary world will do anything about it, I guess I hope that GRUB will change to avoid the problem.




Has anyone seen this happen?  What system/software?  I am now wondering if problem we saw with Roger's machine at the installfest could be related.  I don't think so, but it might impact the new HP machine he bought.  See the HP article reference and the fact the machine came with 4 primary partitions already in place (only noting they are using some of the new techniques).
