The K6 has been reported by some to have problems with make worlds, but I don't ever recall anyone ever saying that it had problems with the Adaptec 2940UW SCSI card. As for why the K6 does not work well doing make worlds, I don't know. It may be an early revision, i.e. 9711xxx, a motherboard compatibility issue, amount of memory (>32MB), chipset, etc. Then again, everyone I have seen here mentioning problems were using Asus MBs with the HX chipset. I guess it is a favorite among most FreeBSDers... In short, there are no hard conclusions. There was originally a rumor that the first batch was recalled (9711xxx may be an early batch but some may have slipped through). It's on that Unoffical AMD Web Site (I posted the URL a while ago.) I think it would be wise to ask him about his bootup Adaptec SCSI configuration to see if there is something there that might cause this problem. Unless you have personal experience that shows that the cpu will not work with this card, I don't think we should jump in and say the culprit is the cpu. Anyway, I use a K6-200 with 64MB EDO Memory with an Adaptec 2940UW and 2 Quantum Fireball SCSI-2 drives and never had any problems with FreeBSD 2.1.7.1R. So it isn't a cpu compatbility issue with the 2940UW here. I have never ran make worlds so I don't know if my cpu works doing that. However, just because there are reported problems with make world doesn't mean the cpu doesn't work at all with FreeBSD because that simply isn't true. In short, the AMD K6-200 runs FreeBSD fine *for almost everything*. The sticky point is whether it can/can not do make worlds successfully. If you never need to do make worlds, then you don't have any problems.
