• Neworking a DOS laptop with PLIP

    Hey folks & fellow retro PC enthusiasts!

    I managed to pickup a pretty mint compaq SLT/386 a couple of weeks ago with working monitor, keybaord, floppy and the original working hard drive (ok its a conner so :( but still... it works!)

    Being a laptop there no expansion slots to put things into & of course it does not have network card. But as well all know, one of the first things one must absolutely do with a new retro PC is to find some way to get it on the Internet!

    I managed to do this using the plip packet driver for dos & using the plip linux kernel module + some config to share Internet access via plip - if people are interested, I'll be happy to explain how I set it all up in more detail.

    Anyhow it did take a while get this working as in the end I had to recompile the kernal with a modified config that had disabled support for IEE 1284 transfer modes in the "Parallel Support section" of the kernel config.

    That made it all work. Without that, I just got lots of "plip0 timeout..." errors in the system logs on the linux server and no connectivity at the laptop end...

    Anyone else played with plip to network an old PC with linux? did you run into this issue? Is there some way to make this work via kernal module option tweaks or some such???

    Just asking as this seems like the sorta thing some of you would have tried, I wonder if any of you have run into the same issue?
