I'm pretty sure I've read somewhere that the status can be gotten from one of the MSR's. It's lousy peace of shit though, it is much better to go with one of the 100-133 Mhz AMD 486's, and it will only run for an hour then it dies, but the fan runs :) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Søren Schmidt (sos@FreeBSD.org) FreeBSD Core Team Even more code to hack -- will it ever end ..
