From Keith Hui:
This patch implements a full SDRAM buffer strength programming algorithm in
set_dram_buffer_strength(), checked against my P2B-LS factory BIOS. With this
in place, I now have 133MHz (!) stability with three 256MB PC133 modules, and
can boot Fedora 11 all the way to the init daemon (actually upstart, but that's
another story). Not to login prompt yet. We'll find out why later.
This again assumes a 4-DIMM board because that's all I have. I need someone
with a 3-DIMM board to test it.
As a bonus, there's a big comment block within that illustrates the algorithm.
:-)
