Hello, |
| 2 |
|
| 3 |
I also have had this problem. The cause was I didn't have the driver for my |
| 4 |
hard drive compiled into the kernel. |
| 5 |
The solution for me was: |
| 6 |
|
| 7 |
#cd /usr/src/linux |
| 8 |
#make menuconfig |
| 9 |
|
| 10 |
Device Drivers ----> |
| 11 |
ATA/ATAPI/MFM/RLL support ---> |
| 12 |
<*> ATI IXP chipset IDE support |
| 13 |
|
| 14 |
The driver must be compiled into the kernel and not as a module. |
| 15 |
You could also look under File Systems ---> and check that all neccessary |
| 16 |
file systems are selected. |
