Hi I think the following should work and if so this approach is simpler. 1. Boot off the install CD like you normally do. Switch to second console and see /proc/pci. Calculate your Append Line 2. Now, reboot with install CD but this time with the Append Line at the boot prompt. 3. You should see both disks as regular IDE disks during installation. Choose RAID and install software (md) raid I recommend RAID 1 atleast for /boot (/ if no /boot) unless ofcourse you intend to build a system with md raid and not ataraid 4. After everything is complete, recompile kernel for ataraid and reboot the machine to launch Linux with ataraid instead of md raid If this method works, one can additionally collect some performance data at the end of step 3 above and compare them against similar data collected at the end of step 4. Although you may decide to use ataraid, such comparison may be interesting. Again if this method works and because md and ataraid are similar, we should look into the code behind that RAID button and implement install time ataraid.
