Hi, I tested 2.6.13-rc7 on nice server motherboard with 16GB of RAM ;) http://www.msicomputer.com/product/p_spec.asp?model=E7520_Master-S2M&class=spd and I see the following when acpi is enabled (haven't even tried without):
# cat /proc/mtrr reg00: base=0xd0000000 (3328MB), size= 256MB: uncachable, count=1 reg01: base=0xe0000000 (3584MB), size= 512MB: uncachable, count=1 reg02: base=0x00000000 ( 0MB), size=16384MB: write-back, count=1 reg03: base=0x400000000 (16384MB), size= 512MB: write-back, count=1 reg04: base=0x420000000 (16896MB), size= 256MB: write-back, count=1 reg05: base=0xcff80000 (3327MB), size= 512KB: uncachable, count=1 # Is that correct?
