sata and ide drives

[mdd0127]

I have a 925xcv motherboard and my main system drive is a maxtor 200gb. The maxtor uses a 40 pin ide to sata converter and plugs into the motherboard on my sata0 port. I bought another identical drive to record on and tried to hook it up with the eide cable. The system tries to boot off the ide drive no matter what I do in bios. I even changed the main system drive to ide and plugged in the sata adapter to the new drive and it still won't work right. I can't figure out how to get my system to boot off the drive that's plugged into the sata port and have the audio drive and dvd/rw in the ide cable. Another thing I'm not clear on is where to install pro tools. It says it's not recommended to record to the system drive. Are you supposed to install protools on the main system drive and save files to the audio drive, or is protools and all of it's associated files supposed to be on the new drive? Probably stupid questions but I've searched my brains out and I'm a bios expert now but it just won't jive. I got it to work for a few minutes by setting the jumper on the new drive to master and the dvd/rw to slave but as soon as I started recording, protools shut down and the systm wouldn't even reboot. I had to use a belkin 4 port powered usb hub to connect the mbox to the 925 motherboard. Could this be causing the problem? We had protools installed on the c drive and everything was working fine until we got a virus and lost everything. Should I get another ide to sata converter to run the audio drive? Any help would be greatly appreciated.

I can answer one part: Install Protools on your system drive.

Primary Master: System/software/paging file
Primary Slave: CD/DVD(if any)
Secondary Master: Audio
Secondary Slave: none

Why are you using a IDE to SATA adaptor? From what I have read those adaptors are so you can use IDE devices on boards that only have SATA. I don't believe you will get any of the advantages that SATA supposedly offers.
