If this fails, proceed as above, but choose Installation--Safe Settings instead. This option
disables ACPI and DMA support. Most hardware should boot with this option.
If both of these options fail, use the boot options prompt to pass any additional param-
eters needed to support this type of hardware to the installation kernel. For more infor-
mation about the parameters available as boot options, refer to the kernel documentation
located in /usr/src/linux/Documentation/kernel-parameters.txt.
TIP: Obtaining Kernel Documentation
Install the kernel-source package to view the kernel documentation.
There are various other ACPI-related kernel parameters that can be entered at the boot
prompt prior to booting for installation:
acpi=off
This parameter disables the complete ACPI subsystem on your computer. This may
be useful if your computer cannot handle ACPI at all or if you think ACPI in your
computer causes trouble.
acpi=force
Always enable ACPI even if your computer has an old BIOS dated before the year
2000. This parameter also enables ACPI if it is set in addition to acpi=off.
acpi=noirq
Do not use ACPI for IRQ routing.
acpi=ht
Run only enough ACPI to enable hyper-threading.
acpi=strict
Be less tolerant of platforms that are not strictly ACPI specification compliant.
pci=noacpi
Disable PCI IRQ routing of the new ACPI system.
Once you have determined the right parameter combination, YaST automatically writes
them to the boot loader configuration to make sure that the system boots properly next
time.
