Any #oldunix gurus around?

ISC Interactive Unix 4.1. Installer (from http://tenox.pdp-11.ru/os/interactiveunix/ ) runs but locks up after partitioning the HDD.
This is on a 430HX, motherboard IDE and a 2GB CompactFlash card, with K6-2 400 CPU and 96MB RAM.
Tried limiting the cylinder count in the BIOS and installer, no change.

Also looking for 3Com 3C509B drivers for the same OS, if anyone has them.

Does anyone know anything about ACCELL UNIFY, ideally the Unix version? Installed version, install media, documentation, anything really.
I'm dealing with an app written with it and the only way to make it work is turn the clock back..... I'd like to fix that!
I could also do with scanned documentation or idiot's guides for #Sybase circa 1992?
