k8 and memory training

by ron minnich

status: train_DqsRcvrEn: end ctrl 0x0 0 done Ram4 stage1 returns run_file returns with 0 Done RAM init code Yep, we got through ram init code. Is it working? We'll see. It dies in disable_car(), which I expected. This is pretty neat .... I think disable_car() will be hard, but we'll get it. I hope to have serengeti doing something interesting by the end of the week. We'll see ... it's off vacation and back to work, so it's back to nights and weekends, but we'll see. thanks ron
