I just noticed I don't have the "Advanced properties" page for my ATA controllers in my win2k box. All the other tabs are there: General / driver / resources. But not the DMA tab. Also the "write cache enabled" is now grayed out on the HD properies page. Any suggestions? I have SP3 with IAA 2.3 installed. Have two HD's primary master and primary slave. Secondary chain is CD and CDRW. Also have a Promise ATA66 card with a lone zip drive on it.
