"Firewire is sharing IRQ with video card and one usb port. I don't

This is probably your issue. With ACPI motherboards along with the
ACPI
Windows HAL, you can't really change the IRQ assignments. Some BIOS
allow a little latitude in this area, most don't.
The reality of this situation is that a lot of laptops are not
going to
be well suited for use as a hardware platform for real-time audio
processing. Laptops are deigned for (a) battery life and (b)
portability. Those design goals are achieved at the expense of I/
O and
processor performance. Occasionally you will run into a laptop that
works just fine. Other times you can get a laptop that has the best
specs in the world and is touted to be a "multi media" high
performance
machine and it just plain stinks up the place when running
PowerSDR. I
have one of the later machines from Dell.
It looks like you have done all the right things as far as
performance
tuning.
Is the version of Windows installed on the laptop one that came from
Toshiba or did you load it yourself from a retail CD? I have found
that
loading the OS myself eliminates any of the integrator installed
"fluff"
programs that they include for usability or support and those get
in the
way of a laptop being able to reach it's highest performance
potential.
I know Neal (K3NC) is looking into a laptop optimized for PowerSDR,
but
due to low demand and high cost may not be offering it as a product.

One other thing you can try is to use the on-board Firewire
interface and
see if that works any better.
Good luck.

All is done and powersdr is not stable.
Using XP with all services (not needed) dissabled.
All hardware not in use is dissabled, indexing dissabled, power
saving in
high performance.
wireless and ethernet dissabled.
Firewire included in the laptop dissabled.
Using an express card firewire card with the correct chipset.
Firewire is sharing IRQ with video card and one usb port.
I don't know hot to change irq in the laptop.
What do tou think?
This laptop was bought only for powersdr, but this is being really
dificult for me.
Thank's a lot.

Ruben and Robert,
Remember that on a laptop to turn the "Power Saving" programs
off, go
into Power Options of Windows control panel, set for "Always On" or
"High Performance" option so that things like hard drives and
external
devices do not time out. You might also check the BIOS and make
sure
that that Intel's Speed Step or AMD's Cool Run is turned off
(this will
slow the processor down) and while in there, make sure in any
Power
window, that timers again are turned off.
This for ALL Windows OSs and machines, I feel that Windows
Indexing
should be turned off. It's built in to Vista, but in XP it was
added as an add on via an update, so check the Add/Remove programs
and make sure that Windows Indexing 4.0 is not installed (it's a
real
CPU
killer) .. Wireless is also something that might be giving
issues,
either through a slow driver or setting for the local network, best
to disable and see if this makes PowerSDR run smoother..
Of course watch the DPC
