Hi, An XO 1.5 here has release 13.2.1. The original SD card remains and storage is near capacity. If the card is replaced with an 8 GB Kingston and 13.2.5 is installed, is any difficulty likely? Thanks, ... Peter E. -- Telephone 1 360 639 0202 or +13606390202 or 12506293757. Bcc: peter at easthope.ca http://easthope.ca/Shop.html
