New Member...hello to everyone. In the process of building two new Shuttle boxes and I've encountered a problem I've been going crazy over for three days. Shuttle SN68SG2/Phoenix Award BIOS/AMD Athlon/Windows XP HomeSp3/500Gb Seagate SATA. Windows appears to have installed okay but every time I boot I get: Boot from CD: NVidia Boot Agent 246.0540 CopyRight NVidia Corp 1998-2004 etc. PXE-E61: Media test failure, check cable PXE-M0F: Exiting NVidia Boot Agent. DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER HOWEVER if I hit "RESET" on the box it boots into Windows every time. I've tried numerous BIOS changes with no luck...I even thought the problem could be caused by the known Seagate Barracuda problem so I installed a WD 500Gb SATA but get the same result. Any ideas??
