I have just built a system for Audio CD mastering with a Teratec DMX 6 Audio card and a ATI Rage Pro AGP card. I find that XP Pro has allocated the same Interrupt (16) to both cards. There are other Interrupts available. When I examine the Interupts in use I find they run up to 18. As far as I was aware there are only 16 interupts available 0-15 and have been ever since the 286 AT was invented way back. The XT only had 8.
Whatever I do I seem unable to change what XP Pro has set up. I have tried disabling the Com and LPT1 ports (They are not needed) to make more interupts available. I also have tried enabling and disabling P & P O.S. in the bios. M/B is an MSI K7T266 Pro 2 6380. The only card is the PCI Teratec and I have tried it in all the PCI slots without change. I am concerned about a clash between the demands of the cards on the processor an Athlon 1800 XP+.
