Nils, the problem with ISA cards is that you either have personally to
assume responsbility making sure hardware resources are assigned
correctly (see: http://linuxmafia.com/pub/hardware/chart.txt), use
ISA Plug'n'Pray -- which never really worked properly, and which is a
kludge in Linux -- or arrive at some compromise between the two.
The "Legacy/ISA" motherboard BIOS settings Paul refers to is a pool of
hardware resources (IRQs, I/O base addresses) roped off from access by
both PCI and ISA PnP cards, and thus available for non-PnP ISA cards
that have been hardware-level configured to use them. In which case,
you get to know the cards' jumpers and configuration utilities really
So, if you want to keep life simple, stick to PCI/AGP cards. If you
insist on using ISA ones, be prepared to _either_ contend with
"Legacy/ISA" resource pools, jumpers, and card-configuration utilities
_or_ get knee-deep in Linux's ISA PnP userspace utilities (if your ISA
cards are all PnP-capable, and have that mode enabled).
On the latter subject:
