While it is an extension of the ISA system, it is not something that can be used with the same drivers as ISA. They are completely separate devices. And almost all systems have ISA devices, even though they have not ISA slots. For example, the mouse and keyboard are ISA devices. In V&, ISA gets built into the kernel whether you have it in your config file or not because too many people assumed that they didn't need it and built broken kernels. Yes, it is possible (and easy) to build a kernel without the ISA device, but it requires modifying another file that is used by config.) Also, some systems will fail to boot if the EISA driver is in the kernel. Rare, but becoming more common as EISA gets rarer. -- R.
