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