Hi friends,

I am working in X86 arch.

In VxWorks 6.6 ATA driver (Legacy driver (Not a VxBus driver) i.e,
INCLUDE_ATA), I am facing the following problem:

In our board, we can connect the two IDE devices. It will be detected
in BIOS as Primary Master and Primary Slave.

If the Primary Master device is not connected, then Primary Slave is
not detected in VxWorks. If both devices are connected, then it is
working fine.

I think, ATA driver has bug.Has anyone solved this problem?

Please give your ideas.
