Where can I find the working drivers for unknown devices of my notebook (Toshiba Satellite) for XP SP3.

what is the model of this PC

M70

Try these drivers:
http://driverscollection.com/?H=Satellite%20M70%20%28PSM70%29&By=Toshiba
You have WLAN, Touchpad, Audio, Power saver, Modem, LAN, Display, DVD RAM, Controls, CardBus. Bios.

See if they work for you, and tell me what else is there after you install those.

I've fixed everything but not the Unibrain 1394 PC,what is this ?

Looks like a Firenet Adapter..
 

try this link..

cannot get it,It says : Unfortunately, the publisher of this program has not submitted any valid download links.

What is the full model code for your M70?  That should help us track the last driver down

I don't know because this PC has given to me from my friend and he doesn't knows.

There should be a sticker on the base with both model number ( "M70- ......") and serial number.

yeah :

M70/215
PSM70E / 01300JI

here you go... bottom of page

---> MariusSunchaser,the website that you have given to me is full of virus and spyware.

Then alternatively you can download the file from here

The file you are after is FireNet3_win.zip which contains the .exe driver installer and .pdf manual
DriverGuide is free to use but requires you to log in with an email address - I use the one I normally reserve for spammers but have never (in over 10 years) had any junk from them.

http://driverscollection.com is full of virus and spyware.

I have posted the link you need above..

here :

http://www.unibrain.com/download/download.asp

and here :

http://members.driverguide.com/driver/detail.php?driverid=979499

there are the same files and they don't work.

What happens if you delete the "Unibrain 1394 PC" entry from Device Manager (effectively removing the device) and reboot?

Thanks.
