BTW: I've set up my asus/p2b/auto.c to mimmick the tyan/s1846/auto.c
So DRAM *should* be working and getting to at least elfboot.
Only things I can think of would be DRAM timing too.
roger, only test with one dimm for now, single sided if possible, and in the first slot. It's very possible that dram init is only working for the first dimm. Once that's working, try to get the rest going. And afaik, the timings being used right now (CL3) should be safe/sane for any sdram dimm. Also check that your dimm(s) are capable of running the same speed as your cpu's frontside bus, I haven't looked at the code recently but I'm going to guess that it's still set up to statically set the ram to the same speed as the fsb. When I was working with it, I was using an old 466MHz celeron (66MHz*7) and PC100 ram to make sure this was a non-issue. Let me know if you need a cpu with a slower fsb, I must have a few dozen old celerons and pentium 2s kicking around, socket 370 and slot 1.
Also, asus p2b's auto.c is fixed in the latest revisions ;)
Good luck! -Corey
