OK, something has happened to the flash chip on my XT-CF Lite, Lo-tech's flash utility will no longer detect what type of flash chip it is, so its attempts to program it fail. The troubleshooting below is with the XT-IDE I assembled yesterday, but I don't have a way to plug a CF card into it. OK, …

Can you post a picture of the entire motherboard ? Some one might recognize it :) Just in case my initial identification was incorrect. (Note that I installed the Cyrix FasMath, and replaced the very dead DS1287 with a GlitchWorks GW-DS12887-1.) IMG_3844.jpeg IMG_3845.jpeg I'm puzzled, what is …
