Hello,
I would think you only need to regenerate initramfs (after having
switched the UEFI/BIOS to AHCI instead of IDE) because last time it was
generated with the dep parameter, the PC was in IDE mode so AHCI was
not included.
if you want to explicitely specify modules for AHCI usage, I think the
name of the module is simply AHCI:
