Serial ATA Boot time out problem

[Charles Johnson <charlesnjohnson tds net>]

When one of my RH9 boxes boots, there is a long pause at the serial ata 
devices, which are turned off in the BIOS, but RH9 seems to discover 
them anyway. Here is what dmesg gives:
=====================
SiI3112 Serial ATA: chipset revision 1
SiI3112 Serial ATA: not 100% native mode: will probe irqs later
, BIOS settings: hde:pio, hdf:pio
