Each PCI slot is "hardwired" to an IRQ channel.
Often two or more slots use the same IRQ channel. Each "channel" can get an available IRQ assigned to it. Thus you can see the problem... A board may share an IRQ with another board since they are both on the same channel. You may have a sound card in slot 4 that appears to have the same IRQ as a card in slot 2. No matter what you do, these two boards will ALWAYS share the same IRQ unless you move one card into another slot. You CAN change the assigned IRQ, but you cannot change the IRQ sharing (which it sounds like you are running into). The easiest way to change the IRQ to channel assignment is to do it in the BIOS. This makes it consistent across multiple OS's... If you use WinBlows and Linux both may utilize the same assignments this way... Although in Windows you may have to go into the control panel and under "system devices" modify the settings so that Windows does not try to reassign IRQ's... -JMS |-----Original Message----- |From: [EMAIL PROTECTED] |[mailto:[EMAIL PROTECTED]] On Behalf Of Michael Dannhorn |Sent: Monday, October 22, 2001 12:05 PM |To: [EMAIL PROTECTED] |Subject: [expert] just one irg for PCI | | | |Hi, | |I have a wonderfull board with ami-bios and there is no build |in way to say |wich irq to which pci slot.
