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.
5 r...@purevil:ttyv0 ~ 15:11:24 fwcontrol
2 devices (info_len=2)
node EUI64 statushostname
0 00-1d-72-ff-ff-c5-6b-71 0
-1 00-1e-8c-00-01-7b-f5-38 0
Then I plugged in the cable:
fwohci0: BUS reset
fwohci0: node_id=0xc000ffc1, gen=8, CYCLEMASTER mode
firewire0: 2 nodes, maxhop = 1, cable IRM = 1 (me)
firewire0: bus manager 1 (me)

crw-rw 1 root operator0, 53 27 Jul 14:56 /dev/fwmem0.0
0 r...@purevil:ttyv0 ~ 15:12:04 more /dev/fwmem0
read error (press RETURN)
The question is.. 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?
Best regards,
EforeZZ
