    sys/dev/ata          ata-chipset.c 
  MFC rev XXXX:
   Do not attempt to enable AHCI mode on ALi SATA controllers other
   than the 5288.
   It is not correctly implemented in earlier silicon, and the BIOS often
   lies about AHCI capability on platforms where these chips are deployed.
   With this change I am able to boot FreeBSD on the ASUS Vintage AH-1
   barebones system.
