I have the same problem installing XP pro and Win2000.I have a Gigabyte board kt400 and an AMD 2000 chip 512k ram. When I try to install XP or Win2000 the files are copied so fast it seems to skip files in the same place everytime before I can finish either installation.I took out the 56x dive and put in a 52x drive. No change. I'll probally put in a DVD drive tonight that will write about 40x to see if this will change,also I changed the speed down to 1500 from 2000 by moving a jumper.It still writes past or hangs on Pro_seg5 file in 2000..A different file in XP. Let me know what this problem could be!!!
