Novell 4.2 smb

Hi,

One customer of mine is running a novell netware 4.2 SMB, the only reason
that the server is still alive are two old dos applications.
Now the server is starting to behave strangely, it crasches now and then
and i would like move the installation to another server.

I got some HP servers, but they are rather new and i can't find any drivers
for these servers.

Besides upgrading to at least novell 5.1, anybody got any good idea on what
kind of hardware i should look have the server moved to that supports
novell 4.2?
