at work we just got our hands on a small machine based on the ASROCK A330ION Micro ITX Atom 330 board with the Nvidia ION chipset & AMI BIOS.
I attempted to install Windows 7 via remote installation, but the GUID exists already (several times, in fact) in our Active Directory. (I'm typically not responsible for installations. I have no idea how the guys went for so long without noticing that the GUIDs were being duplicated left and right)
The GUID is set to 00020003-0004-0005-0006-000700080009 upon boot from LAN, which is obviously a bullshit number.
How can I change this so that Windows 7 will install properly? The other machines are XP machines, and installing Win 7 with Win XP policies doesn't exactly work right...
Edit: I tried putting in a second network card just for the install... didn't work. This board only has 1x PCI-Express slot and the only PCI-Express network card we had laying around didn't want to be recognized by the board.
I found a tool online for AMI BIOS chips called AMIDMI.EXE which has the ability to reprogram the chips GUID.http://www.wintotal.de/server/tipps/amidmi.zip
With that tool, which is apparently from ASROCK for AMI BIOSes (BIOII?), I was able to reassign a completely random GUID to the board. (amidmi /u)
Now Windows 7 is fully installed vis RIS and works as expected.
