Aaaah - the relief! After days of struggling I've done it!! Murty - I can't thank you enough. Without your documentation I wouldn't have made it. I skipped using the promise drivers and went strait for using the ataraid module. To do this I did as follows. 1. Install Mandrake 8.2 on a standard ide bus (hda). 2. Boot into Mandrake with the stock kernel. 3. Download the 2.4.18 kernel - I tried reconfiguring the stock kernel but it never worked. This was where I was stuck longest! Don't bother with the stock kernel - just get a clean one. 4. Configure the downloaded 2.4.18 kernel as instructed in Murty's howto. 5. Move the current kernel out of the way and adjust lilo to this effect. I forgot to do this the first time and the new kernel wouldn't boot - so i was stuck again! 6. Compile and test the new kernel. 7. If all goes well then update the lilo.conf as in Murty's howto and update the fstab file to reflect the new locations of the partitions you want mounted. 8. Apply lilo. 9. Reboot and adjust the CMOS settings as necessary. I had to take out the Primary drive and turn on RAID bios (Fastrack stuff). It took a couple of turns around the CMOS and Fasttrack to get this right. 10. Power down. 11. Move the drive with the installed OS onto the RAID ide bus. In my case this is on IDE3. The mirror drive is on IDE4. 12. Power on and enter the Fasttrack config. Set up the array and duplicate the drive your worked on. 13. Boot with the new kernel. If all went well then you should see /dev/ataraid/d0pX when you type mount or 'df -k'. Thanks to all of you for your efforts and help. I will keep to my word and write up my experience and post it to this list when done. Thanks again.
