Windows needs to be installed on C. Since it's not, you have to make it "think" it's installed in C. That's why you need to put
| Code: | map (hd0,0) (hd1,0)
map (hd1,0) (hd0,0) |
after
and before
| Code: | | rootnoverify (hd1,0) |

GRUB's map command is the correct one to use, but it only applies to entire drives, not partitions.
The Windows section in grub.conf should look like this.
| Code: | title Windows
map (hd0) (hd1)
map (hd1) (hd0)
chainloader (hd1,0)+1 |

It seems that Grub's not looking at the right place. I am not sure that Cyrillic's "chainloader (hd1,0)+1" is required as long as the correct rootnoverify (X,Y) has been specified. Does your grub.conf look like this? | Code: | Title=windows
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
chainloader +1
makeactive

The problem with the map command is that it relates to the BIOS mapping. If you are using any special drivers to access your drives as opposed to your BIOS calls, then it won't work.
Also, can you confirm that:
1. You do not have any other M$Windoze OS' on the same box (any drive);
2. You have not installed Grub's bootloader into /dev/hdb1, i.e. setup (hd1,0), by mistake;
3. The WinXP partition is the only partition with the active boot flag ("a" flag in fdisk).

| Only thing I'd add, is to check that Win *really* is on hdb1 - quite often you find a "recovery" partition first. |
