Minor upgrade

Today I upgraded my Media Server RAID setup.

Before:
One volume per server

RocketRaid 1640 controller
RAID 5 volume, bootable (Win XP + data)

After

NEW: Two volumes per server
NEW: 40 GB IDE UDMA 5 bootable HDD (Win XP + TwonkyMedia server + other software, not shared)
NEW: RocketRaid 1810A controller (hardware accelerated RAID 5 parity calculation)
RAID 5 (4 x 160 SATA 150), containing digital music, images and movies - shared

So, basically I have bootable, not shared HDD for Win XP and data-only RAID 5 volume, shared to my house.
