Problem descrition:

DMA not works in Linux 2.6.12, but in Windows works fine.

DMA not works with HDD and CD drives connected by 80-conductor
cable to secondary IDE port (ide1).


Hardware description:

   1) Motherboard has chipset Intel, Giga-byte
   2) HDD Seagate ST3160023AS (Serial ATA)
   3) HDD Seagate ST3200822A (IDE ATA)
   4) SONY CD-RW CRX320E, IDE ATAPI CD/DVD-ROM


Hardware connections:

   ST3160023AS ---> SATA0 ---> BIOS mapping ---> ide0 Pri master 
 (hda)
                    SATA1 ---> BIOS mapping ---> ide0 Pri slave
   CRX320E     --------------------------------> ide1 Sec master 
 (hdc)
   ST3200822A  --------------------------------> ide1 Sec slave 
  (hdd)
