Yinghai,<br>
<br>
I generally always have my HDT connected, but it looks like it
was just some kind of ghost in the machine. I appear to be getting a
lot further now and am going to keep chunking away.<br>
<br>
Thanks<br>

<p style="margin-bottom: 12pt;"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Greetings,<br>
<br>
I've been experimenting with getting the Cache as Ram stuff working with
my experiments, and have run into a puzzling issue relating to XIP.<br>
<br>
In amd/cache_as_ram.inc, as soon as the writes to MSR 203 completes, my system
crashes. Using my HDT, it looks like the entire memory image gets all buggered
up as well.<br>
<br>
The offending segment of code appears to be:<br>
0008:FFFF7312 B902020000
MOV ECX,00000202<br>
0008:FFFF7317
31D2
XOR EDX,EDX<br>
0008:FFFF7319 B80600FEFF
MOV EAX,fffe0006<br>
0008:FFFF731E
0F30
WRMSR <br>
0008:FFFF7320 B903020000
MOV ECX,00000203<br>
0008:FFFF7325 BA0F000000
MOV EDX,0000000f<br>
0008:FFFF732A B80008FEFF
MOV EAX,fffe0800<br>
0008:FFFF732F
0F30
WRMSR <--------------- POW...<br>
<br>
In my <a href="http://www.google.com/url?sa=D&q=http%3A%2F%2FConfig.lb" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">Config.lb</a>, XIP options are:<br>
<br>
default XIP_ROM_SIZE=65536<br>
default XIP_ROM_BASE = ( _ROMBASE + ROM_IMAGE_SIZE - XIP_ROM_SIZE )<br>
<br>
Any ideas YH? ;)<br>
<br>
<br>
thanks<br>
