Help with RAID

[Ianxxx]

Hope someone can help, I tried to install raid and failed.
could someone make a few points clear for me.
1. boot1h on BOOT or RAID partition?
2. Same with ./boot_v8 on BOOT or RAID
3. Should var be on boot I got a load of errors.
4. Is it possible to install hard links that point to files on RAID rather than actually having the files on BOOT.
