7. CentOS AHCI Platform Boot Failure Recovery
In BIOS version 4.05 series, the SATA driver was switched from Ampere Computing eMAG driver to standard AHCI platform driver. This
creates a disk detection issue at boot time if you originally installed CentOS with Ampere Computing eMAG SATA driver. To recover
from this boot failure, follow the steps below:
1. Boot up CentOS using rescue kernel.
2. Run the following command to see all the currently installed kernel version images.
3. Run the following command to recover the desired kernel.
4. Reboot to that kernel version.
# dracut –f -–kver <desired kernel version>
# rpm -qa kernel | sed -e 's/kernel-//g'
