If there's no PCI host bridge with ISA then check for PCI host bridge with alias "pci0" (first PCI host bridge) and if it exists then choose it as the primary PCI host bridge. This makes choice of primary PCI host bridge more stable across boots and updates as the last fallback candidate for primary PCI host bridge (if there is no choice) is selected arbitrary.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
