SeaBIOS on Bay Trail would time out when trying to access a SATA drive.
Turns out that there's two mistakes in the SATA initialization sequence:
- PCI register 0x94 is wrongly cleared with a bitwise-and operation.
- PCI register 0x9c is instead written to 0x98, clobbering the latter.
After correcting them, SeaBIOS can boot from SATA on Asrock Q1900M.
