Hi all,
I was wondering what the current status of a grub2 port of the grub-0.97
"map" and "rootnoverify" commands is? I have found some work done to
this end in the "drivemap.patch" work, but I find nothing more recent
than drivemap.patch.8 dated around Aug 2008.
I have taken drivemap.patch.8 and made a few updates so that it builds
and works, at least partially, in grub2-r2101. I build "homebrew" linux
systems for my laptops (thinkpads) and desktops and on several of them I
have a 2nd hd installed in the cd-bay with Windows XP. For dual booting,
I've been using grub legasy w/o problems using:
title Windows XP
rootnoverify (hd1,0)
map (hd1) (hd0)
map (hd0) (hd1)
chainloader +1
For grub2-r2101, I use:
### BEGIN /etc/grub.d/40_custom ###
# This file is an example on how to add custom entries
menuentry "Microsoft Windows XP" {
drivemap (hd0) (hd1)
set root=(hd1,1)
chainloader --force +1
}
When I use drivemap as above, on booting Windows I get the message:
unaligned pointer 0x76697264
Aborted. Press any key to exit
I then simply hit "enter," and Windows begins to boot. So, the mapping
works, I do have dual-booting with Windows not on the (bios) first
drive, but mm.c complains about an unaligned pointer.
Could anyone give me any pointers/direction on what might be happening
here? Could it be that the "norootverify"-functionality of grub-legasy
is lacking here? Or, perhaps, that the "--force" option is not being
honored ?
Any help/suggestions/related-info would be greatly appreciated.
Thus far, I have not been able to get a Windows boot using the "-s"
switch of drivemap , e.g., "drivemap -s (hd0) (hd1)" as this results in
a grub Abort, followed by a reboot.
John
