Hi Dudley,
yes, I think this is the only one explain for my problem, my VISTA 64
bit is SP1 and digital sign
disable is only "apparent". If in the hardware resource FLEX5000
appears ready to use, this is false.
The hardware (F5K) is not seen by driver, stop !
There are no reasons for MS to make a free ability to run his VISTA64
without digital sign for the hardware's driver.
If, with a simply boot controlled by F8 option anyone can use his
driver without digital sign requirement, why impose
this requirements for a normal boot ? It is non sense.
Well......very embarrassing situation !
- Flex5000 is one of the best HF radio, and the best combination of
Hardware and Software in SDR.
- HP IQ500 is one of the best and friendly desktop PC never seen before.
- Together may be the best existing SDR system.........when a
digitally signed F5K driver will be ready.
Same situation with other SDR, our "Italian" receiver: PERSEUS
Cypress, the maker of USB chip installed on PERSEUS, did not issue
the 64-bit driver for it.
PERSEUS do not "play" on IQ500....of course.

Beppe,
With the radio being a real-time device, can't wait on
anyone, video being a very busy device, this could be a
problem, but may not be your issue though, I think that it's
Vista 64, particularly if you are running with SP1. I understand
with SP1, MS has killed the ability to run in the test mode to
ignore unsigned drivers. Maybe just out of luck with 64 bit Vista
until a good signed driver appears.

Hi guys,
for last time.......return on problem:
Looking on System Resource of IQ500&Vista64, I found that Firewire
(IEEE 1394)
interface.......share the IRQ16 with the video adapter (NVIDIA) and
with one of the
USB HUB on board too.
Is this the problem ?
In the other VISTA PC I have, the IEEE1394 has exclusive
IRQ.....and F5K works.

Sorry, no... that's not correct.
Windows divides the VIRTUAL address space in half, not the physical
address space. So on any x86 (32-bit) system, each PROCESS has a maximum
4GB of virtual address space, with 2GB (on most machines, for most
processes) reserved for system use and 2GB available to the application.
The physical memory is absolutely not divided in half. That wouldn't
make any sense.
The amount of physical memory used by Windows at any given time will
vary, depending on what's paged in or out. Note that many drivers, as
well as parts of the operating system itself, are pageable (though on
most practical systems today, the OS itself is almost never paged).
Also, parts of the OS (such as the paged and non-paged pools, the
scratch storage area the OS uses for control structures and whatnot)
will expand (within limits) as necessary.
Soooo... If you have a system with 2GB of physical memory, it is
entirely possible that more than 1GB of that memory could be used by a
single process (assuming no competition for memory resources by other
processes, ymmv, etc, blah blah).
Hope that helps,
Peter
