I want to use an SATA drive as a boot drive, with an IDE drive as secondary. The motherboard does not support SATA, I have installed an SATA 1.0 controller into a PCI (NOT PCE-e) slot. The motherboard is an Aopen AK1379G nforce 2 board, 2GB ram, XPproSP3. Q#1: will this work? Q#2: since the controller card is an SATA 1.0, am I limited to SATA 1.0 drives?
I would say that you aren't limited to 1.0 drives, but their speed will be. It is possible to do it, but I haven't done it myself in windows, and it's likely harder that way since windows can be finicky about such things.
I did it with Xubuntu linux and I only had the SATA drive in there. It simply saw it and installed. It even booted from it too. I wasn't expecting that part to work in that ancient P3. It's been running as a file server since.
