Error when installing

[unclebensucks]

I'm getting the following error when I try to install ubuntu on my very old machine:

ACPI: BIOS age (1997) fails cutoff (2000), acpi=force is required to enable ACPI
ACPI: Disabling ACPI support

What do I do now ?

What version of ubuntu? Make sure the version is correct, x86, 32bit.

Update your bios, then go into BIOS, locate Power Management section, and enable ACPI.

If this is not enough then try a different version of Ubuntu or at least a different cd. When you load the cd, hit F6, then add acpi=force
