"Little is known about this problem. Someone who experienced the problem
actually should address the problem. Otherwise, I cannot do anything
with the problem. "

it seems to me there's something quite fundamental you could do without any knowledge 
whatsoever of the specific problems that the map command [as opposed to the map 
person, namely me ... hey, it's my monogram and always has been]  has caused: if you 
were to document exactly how grub effects the mapping, perhaps i -- and others -- 
could at least manage to get out of the tangles the mapping can get one into when one 
innocently uses it without knowing exactly what it's going to do, how to make it undo 
what it did, and perhaps most important of all, whether the mapping is persistent or 
just per-invocation [which would, of course, presumably be clear if the how/what 
information were furnished.

indeed, not to put too fine a point on it, how/what, undoing, and persistence 
information should have been in the manual all the long.  [but please don't make me 
wait for a new manual to find out what i need to know and am too retired to feel like 
digging into the sources to find out for myself.]

cheers, map

Sorry, I forgot to add (re win98 grub cross-booting issues)

I have found a 'map' related issue with grub 0.90-11.

I have 2 hard drives: ide channel 1 primary master (linux)
and ide channel 1 slave (win98). 

I can use the bios (ancient ASUS P5A-B motherboard) to boot from what 
it calls 'C' (ide  channel 1 master) or 'D' (ide channel 1 slave).  Either way  linux 
or win98 boot ok. 

If I use grub in the MBR on ide channel 1 master, it will not boot the win98 on the 
slave (as expected) unless I use the 'map' command in the grub.conf to 'swap' the 
drives around.  

However, even though I can get grub to boot win98 this way, the resultant win98 
environment is broken. The win98 drive (Quantun CR8.4) on ide channel 1 slave is 
chopped up  into three partitions which come up normally as C: D: and E:. If I use 
grub on the MBR of the master to boot win98, it comes up with C: D: E: F: and G: .  C: 
is ok, but D: & E: and don't work at all, and the 'real' 2nd and 3rd partitions are 
now mapped to F: and G:.

If instead of using grub I use lilo, this fault does not occur, i.e C: D: and E: come 
up normally. Also, when booting to the win98 disk from lilo, no screen messages appear 
that you would'nt normally see, but when using grub the 'map' instruction appear on 
the screen in between the various win98 splash screens as they come and go before it 
finally takes over properly.
