While on the topic of lack of documentation, I would like to thank John Gilmore for reminding us about unfulfilled promises and Harald Welte for working with Via to get the Programmer's Guide to the VX855 Companion Chip used in XO-1.5 publicly released. It is linked into the XO-1.5 wiki page: http://wiki.laptop.org/go/XO-1.5#Core_electronics Cheers, wad
