That's fine, but it hardly makes sense to complain about the OS when you know, right from the get-go, that your hardware is outdated. Somewhere around here I have an Pentium-66 board, complete with 4 ISA slots and a VLB slot for graphics, that I could probably get Win2k to install on, but is it really the fault of the OS when the hardware has old-school funkiness about it?
If it doesn't do it correctly and you get a conflict, Intel support will tell you to do just exactly what I said I had to do.. shuffle the boards until you get a workable combination.
Used to be that Intel mobos had a system configuration utility you could download to assign lines manually, assuming you found the one perverse case that broke assignments. Did you ask about that?
This was the old EISA config utilities.. and no these don't exist anymore either.
