Oh, well, I am happy with the software raid that I have been running for years, but still would like to know for intellectual curiosity how to install the bios raid. :-(
But, Tom's comments on Grub were useful. For the record, and any other poor soul with this problem I will now record the solution. As I had already finished my install without grub, I booted using my systemrescuecd (althoughI suppose recovery mode of the install disk would have worked). I then mounted my new root partition (which had my entire system as I only had / and /home partitions defined). Then I did a "mount --bind" for /dev and /proc on top of my mounted new root partition. Then a "chroot" to the new root partition. And finally a "grub-install --recheck /dev/sda" fixed all the problems. Thanks Stuart
