BAD idea. you have to be really carefull with this, or you end up with no 
rw permitions on /dev/null and all kinds of wierd stuff. why not install 
by mounting his under yours, running the Slackware install, set the root 
of the installation on /mnt (or wherever it is mounted) and do it normaly?

he? you mean NT didn't freak out with DM? humm...
I really advise you guys to get rid of DM ASAP, might do some good to 
burn the original diskette while you are at it. LEAVE NO EVIDENCE. TRUST 
NO ONE. <Mulder Out>

there is no way, and believe me, I fought it a LOT, to make Linux grasp 
the DM concept. BIOS based LBA translation transforms the whole disk, but 
DM steals a whole cylender for it's devious plans, and on the N-1 that 
are left, it creates a shifted fake disk, with the new parameters. Linux 
does not know it should be looking for the partition table at a totally 
non-standard sector, and so it sees no DOS partitions whatsoever, in fact 
I remember it sees one huge OS-less partition. dangerous to play around 
with Fdisk in such a situation...

with my 1 GB disk I had a simple solution. back it all up, install a 
512Mb DOS partition with no DM and allocate all the rest for Linux (DOS 
won't see it anyway)

humm... I never saw this... maybe now it DOES support the sector shift? 
try the IDE-HOWTO, or maybe there is onw specifically about large disks.
