Hi Bart,
Yarema did the run test, but the AOpen drive was connected to the PIIX
controller, which is driven by libata:

Hi Yurema,

Could you please redo the IDE test:
1. Connect the AOpen drive to the Promise controller.
2. Configure the IDE pdc202xx_new driver and remove the libata pata_pdc2027x driver.
3. Boot the kernel with IDE pdc202xx_new driver to see if IDE works ok with the AOpen drive?

Thanks.
