I would think the video card is one of the worst devices to share an IRQ with however.
If you can get into your BIOS at boot time, try turning the setting that defines whether you are using a PnP capable OS to On/True or whatever signifies you want the OS to manage IRQs. Usually this is set off because we normally trust the hardware vendors more than Microsoft to manage PnP but if you cannot get a separate IRQ any other way, try turning on this feature which means the hardware stops assigning PnP IRQs and lets Windows give it a try. Its a compromized solution but its worth a try. 73 Neal kn3c On Fri, Oct 10, 2008 at 1:04 PM, Giuseppe Campana <[EMAIL PROTECTED]> wrote: > 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. > > 73 Beppe > IK3VIG > > > www.cqdx.it > > > > > At 17.17 10/10/2008, you wrote: >> >> > >> >The thing most people need to understand is that Windows (XP as well >> >as Vista) divides the memory in half, and gives one half for "system >> >usage" and the other half for your programs. >> > >> >> Sorry, no... that's not correct. >> >> Windows divides the VIRTUAL address space in half, not the physical >> address space.
