[K12OSN] mixing IDE and SATA

[ssh at tranquility.net]

I am putting together a test/home server, and will have to mix one IDE 
drive and one SATA drive (based on the parts I have). The IDE drive will 
be master to the CD/DVD's slave. It will be K12LTSP v6 (I could never get 
v7 to install, tried on both Intel and AMD test machines).

What would be a good mix of partitioning for this setup? This will be 
using tape for backup, so no HD resources need be reserved for that.
