Hi all,
well.. i'm experiencing problems with a highpoint hpt/372-based
IDE raid card.. just really really similar to
the one you can see at
http://www.mail-archive.com/bug-grub%40gnu.org/msg06733.html
Anyway. I have 2 disks in RAID-1 on this RocketRaid board. While
having all the data on a single disk, GRUB worked perfectly because
no RAID was active. As soon as I put the second disk and made
the mirror GRUB stopped to work, even if the copy process terminated
succesfully. I investigated a few..
In a few words, GRUB installs itself in the mbr (first 512 bytes
of the disk). Those RAID controllers changes the last 64 bytes of
the mbr to store the mirror relationship informations.
In fact, by booting with a grub floppy and issuing the
"root (hd0,0)" and "setup (hd0)" commands, the disk came back to boot
but the two disks got magically divided and the RAID-1 relationship
vanished.
Is there any way to solve the problem?

Alessio Orlandi
