The "4" is 406 is for 400 Mhz. The normal value is "a06", where "a" is decimal 10 for 1000 Mhz. The "6" is the voltage selection code; this processor only supports the value "6". Mitch Bradley wrote: > ok 406. 199 msr! > > The period after 406 is mandatory - it forces the number to be > 64-bi

SSE/SSE2 support in os116

2010-03-30 Thread Mikus Grinbergs
Happened to run an older version of mplayer on os116 on XO-1.5, and it claimed "SSE supported but disabled" (also for SSE2). So I looked in some Linux forums, and saw there: "CPUID will tell you whether the CPU supports SSE/SSE2, but not the OS. The OS (linux in this case) can have SSE and/or SSE

G'day, Those of you who have been testing XO-1.5 builds may have noticed that you cannot disconnect from a wireless network, and you cannot discard network history. The workaround was to remove connections.cfg. Per ticket #9977 and #9788, I've made some changes to Sugar network connection handli
