Here we are, still hacking away at 440bx raminit, while I accidentally dropped the list from the trail. :\
Branden told me this: "I did some more testing of the patch train, but didn't manage to figure out where it would boot but with an unstable config. I skipped over 73887, since it was already merged (and master tests okay). 73951, 73952, 74032, and 74033 booted and ran memtest for a few minutes without errors But 74034 would fail with or without debug raminit enabled.
Most of this testing was done with the pair of 128mb capable of 2-2-2-5 timings, but showing 3-3-3-6 as in use in memtest86."
Which seems to reflect my tests as well. Testing continues.
Meanwhile, libreboot made another release with this cruel reality: "Removed boards asus p2b_ls/p3b_f - they didn’t boot properly in pcbox, and the real hardware is basically useless / impossible to find" :( (And they adopted the WIP Haswell NRI we still haven't fully.)

Hi Keith
So far I've only tested the complete patch train (73888) like previously mentioned and didn't have my serial console set up at the time.
I dug out the cable from behind my desk and got it run to my work bench again, so that should help out.
I'm assuming you would want logs with raminit debug enabled though and I didn't have that set last time.
You had mentioned you wanted me to test 74036 specifically?
I checked out the ram I was using with decode-dimms, but didn't check any other ram yet. It looks like they are both rated for CL3 @100mhz and the 133mhz stick seems to run at it's timings for 133 instead of 100? I'm running a 100mhz fsb coppermine cpu and the memory is supposed to run at the fsb speed right? It doesn't seem to use (or at least display it is using) the 100mhz timing on the oem bios either - though I haven't done enough testing to be confident of what's going on.
I have some high density 256mb memory that runs at 128mb with this chipset, so I could check what the timings are on that yet. I really should have just tried to find a lot of 512mb high density to just fill out whatever sdram usage I could have.
