Hi guys,

Please excuse my ignorance in advance, but I am having all sorts of problems and wonder if it might be IRQ sharing conflicts. I'm having problems installing a cd-writer and a new graphics card over the past few weeks. There is something wrong somewhere; I just don't have enough knowledge to knwo what it is. Does the following give any indications?

There appear to be a couple of strange entries there. The IRQ o & 11 for IDE controllers for one. The undetermined entries. I suggest that you enter the BIOS and find an entry called "reset configuration data". Set this to enable and reboot. After one boot cycle reenter the BIOS to verify that this entry has defaulted back to disable. If it hasn't, then reset to disable manually. This should result in a more conventional allocation. while in the BIOS before exiting, I suggest that you also disable any onboard hardware that you don't use. This will free up the resources allocated to that hardware.

Well, it looks like a few things have changed, although the IRQ10 and 11 controllers setting is still there. I don't understand enough to know if this is an improvement or not, LOL
