it's a configuration issue. If you have nvram settings enabled (CONFIG_
USE_OPTION_TABLE), you can enable `sata_ahci_mode` with nvramtool.
No idea why combined mode is the default, it's only useful for OSes from
the '90s. It's not about the type of drives (SATA vs PATA) connected but
how the SATA controller identifies itself to the OS.
Hope that helps,
