Thanks to work on the Dell Mini forum I now have my 8 gig SDHC card working fine. Not sure about everything but it reads and writes fine. Link to the kext is here: [url="http://www.mydellmini.com/forum/download/file.php?id=480"]http://www.mydellmini.com/forum/downloa ... php?id=480[/url] . Link to the forum for details is here: [url="http://www.mydellmini.com/forum/sd-card-slot-creating-developing-the-driver-kext-t360s190.html"]http://www.mydellmini.com/forum/sd-card ... 0s190.html[/url] . Will post comments on any odd behavior if I see any. Big step forward. Now if we could just get sleep to work ....
