i modified 

<param name="core-db-name" value="/dev/shm/core.db" />

to

<param name="core-db-name" value="g:/db/core.db" />

in switch.conf

to run db in a ramdisk for windows xp, which is assigned with volumn g, but then FS is not able to boot up,

the console simply closed after printing

2013-07-06 09:24:02.763297 [DEBUG] switch_nat.c:118 No InternetGatewayDevice, using first entry as default 

(http://192.168.0.100:2869/

upnphost/udhisapi.dll?content=uuid:9fe913c0-45bd-4637-b8fe-a9c380de91d4).

it's not the problem of the ramdisk itself cuz i tried <param name="core-db-name" value="c:/db/core.db" />

and there's the same issue.

so is there any problem for FS to run core db in ramdisk for windows installation, or am i missed any other configurations?
