Upon booting up from the installation CD, after the F6 screen I get the following message: Line 5106 of the INF files is invalid. Setup cannot continue. Please press any key to exit now. My Asus P4P800 (Intel 865G chipset) was spoilt and I replaced it with an new ASRock P4i65G (also Intel 865G chipset). I thought the new ASRock motherboard has problem so I return to the shop and exchange for anther new one but the problem still persist. I only put in CPU, ram and CD-ROM drive during the bootup. It doesn't matter if I put in my HDD or not. I also use another different DVD-writer drive an a very old CD-ROM drive but nothing change. I tried quite a lot of different settings in BIOS but still can't find a clue. I tried using the original Windows 2000 (with no Service Pack) installation CD and another self-made installation CD (with SP4). Both CDs have been used for many installations before with no problem. I also tried install Windows XP but it just hang after the first screen searching for something. Anyone can give some clues? Thanks in advance for any info.
