Serial ATA SIS 964

Hello,

i have written a driver for the SIS 180 Controller (included into SIS964
Southbridge), Motherboard is K7S8XE+.
The Driver is libata-based, running under Kernel 2.6.3

The driver works with programmed IO without problems.
My Problem:
The busmuster dma does not works. I think i must do some special
initialization like the SIS 5513 driver, but i dont have any information
about this chip.

any idea?

with best regards

Uwe Koziolek
