I don't have options called 'memory hole', but in ASUS Commando BIOS I have
option named 'Memory remap', seems this is what you talking about.
By default this option is enabled and FreeBSD/OpenBSD can see 2,1Gb RAM from
8Gb, when I switch off this option - FreeBSD/OpenBSD can see 2,6Gb RAM from
8Gb. The same things I get when use x86 version of xBSD, so I didn't see any
changes when migrate to xBSD 'amd64' version :(
