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)
