A few weeks later our Dell rep pointed me to an ftp site with a newer version:  ftp.us.dell.com/.../r316053.exe.  This worked for me.
Hey group, so while I wait on Dell and other vendors to start pumping out Win 8 certified hardware, I have been running the Win 8 CP on my ST slate since February. With the release of RP this weekend I readily upgraded. Now i was able to get all functionality working previuosly but am now running into an issue with the wireless/BT card driver. Seems Microsoft sees the BT part of the Dell 1535C mini card but will not allow the wireless driver to load. Anyone else with thoughts or experience with this issue? Thanks in advance. Rick
