win7 x54, pentium D, 1GB ram, 1 1gb usb mem stick, 1 4gb usb mem stick, 1 2gb sd card.
started autoconfig, it detected ram, 2 usb's & sd, tested same. speed on sd was abysmal (os says it has an unknown usb type & won't use it for readyboost), so i hit the back button, removed sd and retested. it still said it found 4 devices and crashed when it tried to test the missing sd card. rebooted without the sd, retested OK.
