Hi, I was playing around with fwcontrol and its "-m" switch. I connected my FreeBSD 7.2 notebook to Win7 PC Via firewire and attempted to access Win7's RAM through the /dev/fwmem interface. I failed.

Should this always work? As far as I know I should be able to access other PC's RAM through the firewire connection without any support from the connected PC's OS, right?
