I have a Intel P233 and wanted to upgrade the harddrive to a 20 gig EIDE. I have a 3 gig as of now but am planning on selling it. The problem I have now is when i installed the new harddrive I configured it so It will be the only harddrive on the system. I set the jumpers on the back just like it states and plugged everything in like it should be. It only reads the new drive as 2ndary Master and wont recognize it as Primary master. I set the jumpers differently and still come up with the same thing. It will not recognize the drive as primary master. Can you help me? It is a Western Digital harddrive and i followed the maual just as it said but still cannot get it to work.
