Remove |
| 34 |
Device Drivers -> |
| 35 |
ATA/ATAPI/MFM/RLL support -> |
| 36 |
generic/default IDE chipset support |
| 37 |
|
| 38 |
and |
| 39 |
|
| 40 |
Device Drivers -> |
| 41 |
Serial ATA (prod) and Parallel ATA (experimental) drivers -> |
| 42 |
Generic ATA support |
| 43 |
|
| 44 |
from your Kernel config. You might be using generic drivers instead of |
| 45 |
your specific drivers. Also double check all kernel options concerning |
| 46 |
Disk controllers. |
