First thing I tried was of course Linux. I ran into some problems, however. 1. the SCSI subsystem hung during loading. Before anything card-specefic driver loaded. SMP og non-SMP kernels, same thing. Modular loading of scsi-drivers did the same thing upon loading. Full lockup. Got it partly working on an IDE drive after a while. 2. Linux did only see one CPU. 3. It were highly unstable, even in non-SMP mode. Whats the degree of support in Linux for such an AMD mobo? Is the Athlon MP architecture supported at all yet? I managed to get FreeBSD running on it, and use the SCSI-controller (Adaptec, not sure about what board since I do not have physical access as I write this. Uses the aic7xxx driver, u160scsi). However, FreeBSD would not boot in SMP mode (scsi lockup like Linux did in both SMP and non-SMP kernels, it did see both CPU's however...). Now, shed some light on this. I tried kernels fram 2.0.3x to 2.4.7, 2.0 and 2.2 did alot of really strange stuff, like making user space apps saying "You do not exist"(?). How is the support for AMD Athlon MP, really :-) -- Regards, André Tomt
