Do you or anyone else know where I can get a copy of the IDE standards, I should probably have already read them before I even asked. > > am 100% certain that the hardware I have is performing fine at these > > speeds, > You have an observed aberration, yet you are "100% certain"? Who are > you kidding? I see your point. Someone replied earlier with the incredibly sensible suggestion that I should recompile my ps binary. Worked a treat! So, the hardware was fine after all, I'd just not got the software in proper order. Wasn't kidding anyone, I just hadn't made myself clear. > > Does the following mean that some new PC's are not going to work properly? > > And that FreeBSD just won't support them ? > > No. It means that you are expected to run the parts involved (the > VIA571 and Intel PIIXn) at their rated speeds.

It was probably worth mentioning a long time ago that this isn't an Intel chipset based board: ide_pci0: <VIA 82C586x (Apollo) Bus-master IDE controller> rev 0x06 on pci0.7.1 Hypothetically : If I purchase a 6x86 that is supposed to run at 188Mhz, and hence a bus speed of 75Mhz (and run it on this board - an FIC PA2007) does this mean that the frequency the IDE devices are clocked at is greater than 30 or 33Mhz ? If so, then would a correctly configured system still work as you say? As this isn't what the comment in the code implies to me. If not, then I think I realise whats going on, but don't see how one would overclock the IDE devices (the code implies that it's possible). If I've got something wrong then please could someone explain it to me. I just wanted to know how/why it works or doesn't. P.S. I'm talking about a hypothetical system here, which isnt overclocked.
