Yes, you've discovered a "feature" of the 400SC (I have 3).  If you
have PATA and SATA disks installed:

SATA disabled in BIOS -> PATA boots
SATA enabled in BIOS -> SATA boots, and stops if it can't (PATA never attempted)

The best work around is to install a boot loader on your SATA HD to
point to the PATA HD.
