ed1k just announced that he had ported SETIRQ, a utility originally written for DOS, to QNX 6 (x86 only). It is a command line utility. "setirq list" will show you the list of devices which uses interrupts. "setirq set link,irq" will assign given irq to devices with given link. All information about link numbers and possible IRQ is displayed by "setirq list" command.More detailed help as well as author's e-mail address for feedback can be obtained by "setirq -vvh". It is not a Windows "Device Manager", but it is better
than nothing.
Cautions:
1. It doesn't work in pre- QNX 6.2.0 releases.
2. You must slay all drivers for affected devices before issuing "setirq set" command.
3. Although many BIOSes report IRQ 6,14,15 as available for PCI IRQ steering, you should remember that these IRQs are usually used for FDD, IDE0 and IDE1 respectively. You can try to use them if you don't have some (or all :)) of those devices.
4. Dealing with this stuff, you should expect possibility of resetting/rebooting of your PC. So, save your work beforehand and don't blame the author for data loss, damaged hardware etc.
