the following bugs. - When constructing a resource configuration, respect the order in which resource descriptors are read, in order to establish the correct mapping between the descriptors and configuration registers. "Plug and Play ISA Specification, Version 1.0a", Sec 4.6.1, May 5, 1994. "Clarifications to the Plug and Play ISA Specification, Version 1.0a", Sec 6.2.1, Dec. 10, 1994. - Do not ignore null (empty) descriptors; they are valid descriptors acting as filler. "Clarifications to the Plug and Play ISA Specification, Version 1.0a", Sec 6.2.1. - Correctly set up logical device configuration registers for null resources. "Clarifications to the Plug and Play ISA Specification, Version 1.0a" - Handle null resources properly in the resource allocator for the ISA bus.
