by using config()?
You can't use config to toggle bigmem. You need to set the bigmem
variable to 1 in /usr/src/sys/arch/amd64/amd64/machdep.c, then you
compile and install a new kernel.
http://www.openbsd.org/faq/faq5.html#BldKernel explains how.
I'd gathered that from reading one of those threads to the end. I
really wanted to avoid having to build a custom kernel, especially if
the results might not even work. I suppose I was just inquiring about
the status of bigmem in 4.5 and if it is considered "safe" to use yet?
