My ps2 mouse uses IRQ12, which is definitely in the range of the interrupt a soundcard would use. With "isapnp" and "pnpdump" you should be able to change the cards interrupt. ISA and PNP have ever been a problem for linux, as it is not supported by the kernel directly. I still doubt that these cards would work without the -frags, as the driver probably isn't good enough.

Well, yes the Pinnacle works just fine using the -frags flag, though it 'blue-screens' doing duplex under NT (this is a Pinnacle driver problem which is not restricted to PD; it has proven to be a nightmare for us actually).
Re: the mouse problem: I'm using a PS/2 mouse on both machines. Don't know if that elucidates anything. As you say, could be to do with using the ISA bus, I hadn't thought of that.
