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. |
