This device is using an Interrupt Request (IRQ) resource that another device is using.
An IRQ cannot be shared. This might occur when a PCI/EISA SCSI controller is sharing an IRQ that is also in use by a real-mode device driver that Windows 2000 cannot change.
Remove the real-mode driver that is using the same IRQ as this device. The real-mode driver might be loading in the Config.sys or Autoexec.bat file.
