### Ukuhlohlwa kwe--ACPI Kususwe Isakhono

Current hardware usually requires ACPI (Advanced Configuration and Power Interface) to control the interrupt handling. ACPI completely replaces the old APM system.

Select Ukuhlohlwa kwe--ACPI Kususwe Isakhono if you encounter problems during boot of the kernel. Known problems with machines that have problems with ACPI are:

- kernel freezes when booting
- PCI Cards are not detected or initialized properly

You may also try the Uvavanyo lwe-Firmware boot option and look at the test results of the ACPI validation.
