There used to be a thing called the hardware list. I know it is boring to rise up this again, but perhaps it is just something that should exist. I know that the total number of motherboard configurations is the number of different motherboard brands (incl. revisions) times the number of graphics cards times the number of disk controllers times the number of disk brands times the number of disk brands time the number of pocessors (yes, Cyrix, Intel, IBM, TI and others have succeeded in making a real lot of different 486 chips and I feel that the number of 586 chips may be round the same in some years) times the number of serial boards/whatever. Still I think it would help if we had the list of working/non-working configurations. I know I have proposed it at least once (and saw no answers). But if there are people who will send me their configurations, I will collect them together into a single file (or bunch of files sorted upon different criteria). It may also in the long run keep down some of the bandwidth of the mailing lists if the files were mentioned in the READMEs. So mail-bomb me with uyour configurations... :) > Advice to people setting up news servers, gateways, or personal play > machines.
