Because it's a hardware property. The error means a single bar needed 4GB or more of address space, btw. Sounds like something is wrong :-) > Perhaps the pref64 bit is set by default by the hardware; if so, is > there a way to clear it in LinuxBIOS? No. BARs are 64-bit or not, there's no way to change that. It doesn't matter however; if the top half of a 64-bit BAR is set to zeroes, it works fine on a 32-bit system.
