It's packaging... here is some info from the config... --- cut --- # CONFIG_BLK_DEV_ALI15X3 is not set # CONFIG_BLK_DEV_AMD74XX is not set # CONFIG_BLK_DEV_CMD64X is not set # CONFIG_BLK_DEV_TRIFLEX is not set # CONFIG_BLK_DEV_CY82C693 is not set # CONFIG_BLK_DEV_CS5520 is not set # CONFIG_BLK_DEV_HPT34X is not set # CONFIG_BLK_DEV_HPT366 is not set # CONFIG_BLK_DEV_SC1200 is not set CONFIG_BLK_DEV_PIIX=y # CONFIG_BLK_DEV_NS87415 is not set # CONFIG_BLK_DEV_OPTI621 is not set # CONFIG_BLK_DEV_PDC202XX_OLD is not set # CONFIG_BLK_DEV_PDC202XX_NEW is not set CONFIG_BLK_DEV_RZ1000=y # CONFIG_BLK_DEV_SVWKS is not set # CONFIG_BLK_DEV_SIIMAGE is not set # CONFIG_BLK_DEV_SIS5513 is not set # CONFIG_BLK_DEV_SLC90E66 is not set # CONFIG_BLK_DEV_TRM290 is not set --- cut --- So there are a lot of ide chipsets that will run in pio-mode only, In your case it's the: # CONFIG_BLK_DEV_AMD74XX is not set wich needs to be changed...
