Description Bhavna Sarathy 2007-10-01 19:26:51 UTC

+++ This bug was initially created as a clone of Bug #314571 +++

Description of problem:
SB700 supports one physical IDE channel, but SB700 SATA controller
supports combined mode. When the SATA combined mode is enabled,
two SATA ports(port4 and port5) share one IDE channel from IDE
controller, and PATA will share the other IDE channel.

Our previous patch adding SB700 IDE device ID supported one
IDE channel. The attached patch supports two channels for the 
latest hardware.

The attached patch has been sent to the linux kernel IDE maintainer, 
and once accepted the upstream git link will be submitted to the BZ.
