I purchased 2 PC's - both exactly the same. The first message says PXE-E6: Media test failure, check cable Then reads: Disk boot failure.... I can't imagine what cable it is describing, let alone on both PC's. I suspect it is trying to locate a server which no longer exists. It detects the CD-Rom, floppy, and hard drive in BIOS. I have the booting order as: floppy, Cd-ROM, and HD. Diskette is acknowledged. HD is PRI Master CD is SEC Master The motherboard is an ASUS Pentium 4 NIC Thanks in advance for anything you have to offer.
