bogo-howto: ATA-100 drives on the Asus A7A266
People are using the archive and discovering my earlier question about getting my ATA-100 drive to work on the Asus A7A266, and are now writing to see whether I ever got a solution.
I did, and since I have had a number of enquiries I decided to excerpt the correspondence as a pseudo-howto. I am posting this message in hopes that others may find the information useful.
The information is at

Good luck with it, and holler if you have better suggestions.
