What do the Ubuntu Live CD F6 Other Options mean?

[Rytron]

Hi.
When the Ubuntu Live CD is booted from you get many more options at the end of the screen.

Under 'F6 Other Options'
acpi=off
noapic
nolapic
edd=on
Free software only

The 'Free software only' option is obvious but what do the other options mean exactly?

Thanks.

These options in Boot Options are for machines that don't have support for acpi, apic or lapic.

without these appropriate options being selected the install will likely not succeed, if it can even begin in the first place.

Thank you presence1960. That is a comprehensive answer.
