220 Start-Up<br />

acpi=<strong>of</strong>f<br />

This parameter disables the complete ACPI subsystem on your computer. This may<br />

be useful if your computer cannot handle ACPI at all or if you think ACPI in your<br />

computer causes trouble.<br />

acpi=force<br />

Always enable ACPI even if your computer has an old BIOS dated before the year<br />

2000. This parameter also enables ACPI if it is set in addition to acpi=<strong>of</strong>f.<br />

acpi=noirq<br />

Do not use ACPI for IRQ routing.<br />

acpi=ht<br />

Run only enough ACPI to enable hyper-threading.<br />

acpi=strict<br />

Be less tolerant <strong>of</strong> platforms that are not strictly ACPI specification compliant.<br />

pci=noacpi<br />

Disable PCI IRQ routing <strong>of</strong> the new ACPI system.<br />

For more information about these issues, search for Support Database articles with the<br />

keyword “acpi” at https://portal.suse.com.<br />

Once you have determined the right parameter combination, YaST automatically writes<br />

them to the boot loader configuration to make sure that the system boots properly next<br />

time.<br />

If unexplainable errors occur when the kernel is loaded or during the installation, select<br />

Memory Test in the boot menu to check the memory. If Memory Test returns an error,<br />

it is usually a hardware error.<br />

9.2.4 Machine Fails to Launch the Graphical<br />

Installer<br />

After you insert the first CD or DVD into your drive and reboot your machine, the installation<br />

screen comes up, but after you select Installation, the graphical installer does<br />

not start.
