Sometime later, it is likely that the current versions >of *BSD will support broken hardware, but not yet. Linux doesn't jump through any hoops. I guess BSD doesn't jump through the proper ones. With respect to this I'd suggest the original author tries the current NETBSD. The old 386BSD had so many bugs with device drivers and general memory handling that have been fixed that NetBSD may well work. On the other hand I'll stick to Linux. >In the meantime, make sure motherboards do caching correctly and make sure >IDE cards handle things correctly.

Good advice for all barring IDE cards don't cause any cache problems because neither Linux nor BSD use IDE DMA mode, and since IDE drives that support it are as common as a live dodo.
