(Michal Necasek - There was an update to 1.34)
The remote boot ROM/code is Token Ring only. It’s
possible to adapt the sample program to Ethernet but it
won’t run as is (the send buffer it allocates is 2K, while
IBM’s 802.2 stack only supports up to ~1.5K for Ethernet).
The RPL User’s Guide is quite useful and
probably the best documentation available. There were other
editions of the RPL User’s Guide but I’ve not seen those.
Over time the support was built into server products (PCLP
1.3, LAN Server) so it the detailed low-level documentation
wasn’t as important.
I’m actually unsure how much code the DOS LAN Services
shared with PCLP; there could well have been some. The
biggest(?) difference was that PCLP provided a DOS-based
peer to peer network while DLS was AFAIK strictly clients on
the DOS side, no file sharing from DOS machines.
Though I think it’s fair to say that DLS replaced PCLP
in IBM’s product portfolio as the servers shifted away from
WBST: As with many things IBM, names morph over time as
Marketing input sways decisions. IBM's DOS PC LAN Program
became "DOS LAN Services" (v4.0 latest?) as distributed with
IBM's Warp Server v4.0 (Warp 3 based) and on the ServerGuide
