The Egret system controller was the predecessor to the Cuda and the differences are minor. On Cuda, byte acknowledgement requires one transition of the TACK signal; on Egret two are needed. On Cuda, TIP is active low; on Egret it is active high. And Cuda raises certain interrupts that Egret omits. Accomodating these differences complicates the Cuda driver slightly but avoids a lot of duplication (see next patch).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
