Hi all, I replaced the cdrom drive in my dell dimension pentium 2 400Mhz 128Mb RAM with a cd writer (Philips 5200 series PCRW5232K). I set the jumpers to master (I also tried cable select)and I powered up the machine. The HD spins up and the cd writer receives power but the boot process does not even get as far as showing anything on the monitor. There are no POST beeps at all. I then replaced the cdwriter with my old cdrom drive expecting everything to be back to normal and I have exactly the same problem. All ribbon cables and power connections are firmly seated. The video card is working fine. I tried disconnecting and reconnecting all my IDE cables. I tried all jumper positions on each drive. Please help I am now without a functioning PC. Thanks Andrew
