The attached dmesg_libata_force_80c.txt (dmesg) file shows the details of doing a warm boot with the LiveCD on my desktop computer that did not have Ubuntu installed on it.

I have a ThinkPad without a HDD plus a laptop adapter that will hold my CF card, but my Think Pad is a lot older than the ones discussed on Compact_Flash_boot_drive.  In addition, I did not see any recent updates to this Internet page, but maybe I can find someone to email who will update this page.

Is there actually any way to identify the adapter automatically? AFAIK, 
these CF-IDE adapters are just passive circuitry and there's no way to 
identify them through software.
