There isn't reason why not. Yes, I too had problems with win96 and winNT
about this kind of changing, but I don't think Linux will ever complain.
There's no registry to brake on it :-)

However, you have some issues (strictly hardware related) to overcome. The
first and most important is the way the BIOS sees the disks. Most old
BIOS' weren't able to see well disks bigger tha 512 Mb. In order to
overcome this, you were able to choose in the BIOS special ways to access
the disks, called LBA and BLOCK. Be sure you take note what kind of access
your P200 uses and make EXACTLY the same thing in the 486's BIOS. If that
particular BIOS on the 486 wouldn't let you, you're caught.

Another big issue is to have the disks hooked on the 486 in exactly the
same manner as on the P200. Especially the root partition has to be on the
same place as before. Let's say you had Linux on the first logical
partition of the primary master disk (this is /dev/hda5) then when you
move the drives to 486, you have to hook that primary master disk as
primary master on the 486. It the 486 supports only 2 disks (a master and
a slave) then your previous primary master becomes the master in the new
computer. There are many complications with this particular issue. But if
your root partition gets properly hooked, then the others can be recovered
by editing the /etc/fstab file.

Another issue concerns your kernel. If it was a standard RH kernel, used
on standard hardware, all it's OK. But if you compiled your kernel for
special features (strange SCSI cards or such) I don't have any idea what
will happen with the not used symbols (as a matter of fact I think it
doesn't vow even with broken hardware relation, but I'm not sure).

Hope this helps
