PCI Lookup is desinged to help you find the Vendor and Device descriptions you need to get drivers for your PC. If you are not sure where to start, there is some helpful information below that can get you started. If you are still lost, feel free to cont
先是来源于/drivers/pci/probe.c的pci_setup_device(),后者通过调用 pci_read_irq()也就是读取设备的IRQ Line(0x3C)。 如果为0,在pcibios_lookup_irq()结尾处的代码,会把它变为其他具有相同PIRQ号的 设备的IRQ号,当然如果不是0,而且又不和其他具有相同PIRQ号的设备的IRQ号一致, 那就出错。另外,如果BIOS...

Look up your device on pcilookup.com to identify the vendor and the device description. For example, the above VEN and DEV values give the following result. With the vendor and device information identified, if the hardware is from NI, then follow the steps in Windows Does Not Have a Dr...
Both denote configuration issues, particularly "The drivers for this device are not installed (Code 28)". For context, the PCI Serial Port has a: - Hardware ID of: VEN_8086&DEV_06E3&SUBSYS_1B9715D9&REV_00 - PCI Lookup Description of: Comet Lake Keyboard and Text Redirection For cont...
