In order to reduce the size, some port adapter drivers are not included in the boot image. When the boot image is loaded, certain port adapters will not be supported.
This error message indicates that the port adapter specified is not supported by this boot loader.
If support for the specified port adapter is needed when running the boot loader image, configure the router to use a full image as the boot loader.
For more information, refer to Field Notice: Oversized Cisco 7200/uBR 7200 BootImage.
