hello misc@
I took the time to install OpenBSD -current on a new computer I just built
It does not see 4GB of memory out of the box, is there something I

have to compile in the kernel to get this to work?
The motherboard is an Asus Striker Extreme it has 4 1GB memory

modules, and an intel Quad Core cpu
below is a dmesg

That looks normal for 32bit operating system trying to address 4GB, the

OS still needs address space to PCI devices. I'm not sure of the status

but the amd64 port might support of 4GB.

just as i386 doesn't run on 80386, amd64 does run on Intel Core 2 processors

Silly me for assuming that the "amd" part  of amd64 meant "only amd" lol

I was wondering why the BSD's never had x86-64 like linux does.

Now I understand that amd64 is for both amd and intel alike.
Thank you guys, the thing I love about this Open Source stuff is that

it sparks new learning everyday.
