If you are not sure, say N here.
config ACPI_IBM_BAY
bool "Legacy Removable Bay Support"
depends on ACPI_IBM
default y
---help---
Allows the ibm_acpi driver to handle removable bays. It will allow
disabling the device in the bay, and also generate notifications when
the bay lever is ejected or inserted.
If you are not sure, say Y here.
config ACPI_TOSHIBA
tristate "Toshiba Laptop Extras"
