Summary:  Cannot boot Windows XP on hd1; 'map' command doesn't work

Original Submission:  I have the following disk set-up:

/dev/hda1 *  20GB  Debian Sarge (mounted as /)
/dev/hda2     2GB  Swap Space

/deb/hdb1 *  40GB  Windows XP

My Windows grub menu.lst entry:

title Windows
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd0,0)
makeactive
chainloader +1
boot

When I select this entry, grub reports

  Error 13: Invalid or unsupported executable format

If I use 'root' instead of 'rootnoverify', I get this additional message:

  Filesystem type is ext2fs, partition type 0x83

If I get rid of the two map commands, I get the same message.  It seems that 
the map commands aren't working.  If I do 'root (hd1,0)', I get this message:

  Filesystem type unknown, partition type 0x7

but then the machine freezes.  Adding back the map commands doesn't change 
anything.

Thinking that this might be a issue with the location of /boot on the drive, I 
repartitioned & reinstalled Debian with this configuration on hda:

/dev/hda1 *   1GB  ext3 /boot
/dev/hda2    19GB  ext3 /
/dev/hda3     2GB  Swap Space

I got the same problem as described above.  I then decided to swap the drives 
and reinstall (so that I wouldn't need to call 'map' to boot Windows XP).  New 
configuration:

/deb/hda1 *  40GB  Windows XP

/dev/hdb1 *   1GB  ext3 /boot
/dev/hdb2    19GB  ext3 /
/dev/hdb3     2GB  Swap Space

Windows /boot/grub/menu.lst entry:

title           Windows 95/98/NT/2000
root            (hd0,0)
makeactive
chainloader     +1

Now I can boot Windows XP.

This may be related to bug #9159.
