The models up to (but not including) the 50 series were ISA and after that were
microchannel. The 25 came out originally as an XT class machine with an 8086
processor ( see
http://www.can.ibm.com/helpware/8525.html ) and the 286 version of
it was only one version that I'm aware of as seen at
http://www.can.ibm.com/helpware/8525286.html
The LS may be an aftermarket version, much like putting a Reply motherboard into
one.
All the info on the vintage IBM machines can be found starting with the index page
