I have an Asus Av133 which has an onboard Promise ATA100 controller. I have installed winxp home version on a Maxtor drive on the Primary ide(not the promise controller) and have an ibm drive on the promise controller. I am booting from the Maxtor, primary ide. My Computer does not show the ibm drive. The promise controller and the ibm drive show in device manager as working ok. I have tried showing all files, doing a hardware detection, removing the items in device manager(they are found again, but don't show in My computer). Everything else in my system(two cdroms, and internal zip drive) show ok. Searched for an udated driver at MS, no luck. any ideas?
