I have had problems with the PLX PCI9052 and certain versions of the
Compaq EVO series. It appears to be a BIOS problem, they aren't allowing
the PLX chip enough time to load from the EEPROM. At least, that was
PLX's view of the problem (of course, Compaq never replied so I don't
know what theirs is).

If your end system is DOS based, if you poke the correct values to the
registers, it works fine thereafter. I expect you can do it with some
Windows versions too, though not NT, MX etc. But plug and play might
mess things up if any hot plugging happens.
