Title: Changing IRQ
Post by: Waffle on April 23, 2005, 03:41:05 PM

How would one go about doing that? Bios?


Read in another thread about sound cards sharing IRQ with network cards...

Well...you guessed it...lmao got a few sharing...not sure if a big deal, or if sorting the issues out would help with perfomance.

well you could disable the com ports if your not using them to free up those 2 irq's  , i also disable the 1394 ports on my system aswell . most people dont use the com ports if they are on broadband through a nic card, do u use the 1394 ports? id disable atleast the one sharing with the VC , but if your not using the port im not sure if it would cause any problems due to the port not trying to access the system         38

Sometimes it's a simple as changing the PCI slot the card was in. I used to work on some of the older Gateway computers and if the LAN card would not work moving it to another PCI slot ussually fixed it. I would move it into the lowest number slot you have open.

You can hard set an interupt in BIOS for a particular PCI slot if you want but I would do this as last resort.
