THAT Compaq chip set ... The next FreeBSD SNAP will use the PCI probe code from FreeBSD-current, which should work a lot better on your system ... Perhaps we can get Jordan to release a pre-SNAP boot floppy, which would help somebody else, too ... (Hi Jordan, how about it ???) } Gary said this may be of some importance. Well, yes, and he was right :-) But it won't help you, sorry ... :( The problem is that Compaq has a long history of chip sets which break the (PCI) rules. I received mail from a Compaq engineer who told me, they did compensate for that in software (BIOS and drivers) and saw no need to make their hardware behave according to the PCI spec. requirements! This means it is not possible to make a save distinction between PCI and some EISA chip sets, and since I could not risk loosing EISA support in FreeBSD-2.1, it was impossible to correctly deal with all those Compaq chip sets :( Your best bet is either installing to that SCSI drive connected to another computer (you'll have to weaken a test, or just compile in a file from -current). Then you still have to make sure, that the "nca0" driver can be made to work with the AMD SCSI+Ethernet Combo chip.
