i just finished setting up my SMP system. ASUS A7M266-D with dual Athlon MP 2000+.

OS : Windows XP Pro

System works fine and see's both CPU's however when i try to run 3DMark2001SE which i just downloaded last night and installed. I get the following error when i try to start it -

3DMark2001 SE requires a processor with MMX instructions.

We recommend that you upgrade your computer or test your PC with an older version of 3DMark.

I looked in the error log it generated and it seems to be able to detect everything on my system except the CPU. Can't seem to recognize it.

Here's a snip from the log

Application info

Name 3DMark2001 SE
Build 300

Error log

MMX instruction set required.

System info available: yes
Project available: no

System info

System Info Version 2.2
Installation ID 0x00000000

Family <unknown>
Internal Clock 0 Hz
Internal Clock Maximum 0 Hz
External Clock 0 Hz
Socket Designation
Type <unknown>
Upgrade <unknown>
Capabilities none
Version N/A
CPUID 0x00000000

After this it shows all the info for my DX, Vid card, RAM , HDD etc etc ..

I then downloaded 3DMark2000 and that seems to work fine but it doesn't use DX8.1.

Just wondering if anyone has run in to this problem?
