 *      If you are using Marvell SATA-IDE adapters with Maxtor drives
 *      ensure the system is set up for ATA100/UDMA5, not UDMA6.
 *
 *      If you are using WD drives with SATA bridges you must set the
 *      drive to "Single". "Master" will hang.
 *
 *      If you have strange problems with nVidia chipset systems please
 *      see the SI support documentation and update your system BIOS
 *      if necessary
 *
 *  The Dell DRAC4 has some interesting features including effectively hot
 *  unplugging/replugging the virtual CD interface when the DRAC is reset.
 *  This often causes drivers/ide/siimage to panic but is ok with the rather
 *  smarter code in libata.
