Dear list I followed documents I found on the Internet which says by editing /boot/device.hints I can assign IRQ or disable devices, and I tried to do so, modification in /boot/device.hint do have effect over some device, for example: hint.fdc.0.disable="1" but some seetings do not have effect, e.g. hint.uhci.0.disable="1" No matter what I set to uhci (irq, disable, port, at etc), none of them works, next time the OS start it will always discover this device and assign the same irq, same port: [zhangweiwu@quasimodo ~]$ dmesg | grep hci uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0x9000-0x901f irq 11 at device 6.2 on pci0 uhci0: [GIANT-LOCKED] usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0 [zhangweiwu@quasimodo ~]$ Where can I get knowledge of how device.hints works? e.g. maybe it can only work with device that is not managed by a PNP BIOS or maybe it only manage ISA devices but not PCI devices? Thanks!
