vxWorks bootrom是基于vxWorks系统定制的一款boot loader， 由windriver公司自己开发的专用于vxWorks引导。其性质与uboot的一样，在参照vxworks bsp信息的基础上我们可以用修改uboot来取代windriver自己bootrom以引导vxWorks。网上有相关文档《vxWorks从bootrom到uboot》。
在vxWorks的集成开发环境workbench中我们可以很方便的得到bootrom image。像创建VSB或VIP一样，创建bootrom project，然后编译得到bootrom.bin。
windirver对bootrom官方的解释是：
The boot image is a specially-crafted version of vxWorks with a boot loader as its only application. Because this boot image is largely independent of development changes, it is seldom neccessary to re-progarm the flash, which saves development time. The boot image is reffered to as bootrom; the OS image that is loaded is referred to as vxWorks. These images are described later in the document.
