Hi, I'm trying to get a on-board PDC20265r "raid" controller to work with the ataraid driver... Unfortunately I had no luck yet... The problem seems to be that the disks of the raid-1 array are detected as hde and hdg. Next the promise fastrak driver tells me that "No raid array found", which is strange because I rebuild the whole array and the controller says there is one. During Kernel compilation I selected CONFIG_BLK_DEV_PDC202XX, CONFIG_PDC202XX_BURST, CONFIG_PDC202XX_FORCE, CONFIG_BLK_DEV_ATARAID, CONFIG_BLK_DEV_ATARAID_PDC and CONFIG_BLK_DEV_ATARAID_HPT thanks for any advice, andreas The Kernel messages are the following: Aug 30 13:14:29 dyn119 kernel: PDC20265: IDE controller on PCI bus 00 dev 80 Aug 30 13:14:29 dyn119 kernel: PCI: Found IRQ 11 for device 00:10.0 Aug 30 13:14:29 dyn119 kernel: PDC20265: chipset revision 2 Aug 30 13:14:29 dyn119 kernel: ide: Found promise 20265 in RAID mode.
