You mean like this:
revision 1.123
date: 1995/11/29 15:00:07; author: bde; state: Exp; lines: +5 -10
Removed builtin list of port addresses. The address for sio3
conflicted with S3 graphics cards. Now users should put sio[2-3]
in the config file if the hardware exisst, even if the probe is
certain to fail due to an interrupt conflict. Otherwise, ports
sharing the interrupt may fail the probe if the system is warm
booted while sio[2-3] are active (perhaps under another OS). The
same problem for nonstandard ports is now handled better than
before.
Thanks Bruce!! (Any chance of this code going into -stable though...)
