but OpenBSD 4.7/amd64 SMP detects only 3 GB.
Is there anything more I should do to get the other 1 GB of RAM
recognized by the System?
This is normal. Large memory support is not yet included in
OpenBSD by default for amd64.
Is there anything I can do to get this by recompiling the kernel or
something?
Yes and no; google for 'bigmem' in the misc list for marc.info. You have to
edit
a source file and recompile the kernel.
However, it won't work (to be precise, it will probably crash on boot, or
possibly
afterwards) unless you have an IOMMU, and most Intel systems don't.
OpenBSD doesn't support the AGP/PCI-e GART as an IOMMU, and I'm not sure
if it supports VT-d platforms (which you probably aren't running anyway).
The
only option here is AMD.
Until the devs tell us it's working, it's not worth persevering with.
