That's because it's not longer there: |
137 |
|
138 |
$ cat /usr/src/linux/.config | grep -i CONFIG_ATA |
139 |
# CONFIG_ATALK is not set |
140 |
# CONFIG_ATA_OVER_ETH is not set |
141 |
CONFIG_ATA=y |
142 |
# CONFIG_ATA_NONSTANDARD is not set |
143 |
# CONFIG_ATA_VERBOSE_ERROR is not set |
144 |
CONFIG_ATA_ACPI=y |
145 |
# CONFIG_ATA_SFF is not set |
146 |
# CONFIG_ATARI_PARTITION is not set |
