Catalyst CatScan
is a Windows-based PCI/PCI Express configuration space Read/Write
utility that allows the user to scan, decode, display and
write to the system configuration registers. The user interface
provides a detailed display of the devices present on the
system, with color codes to allow easy visualization of different
registers and capabilities. The user can decode and change
each bit value of any register on the fly without flipping
any pages on the PCI Specification. It also displays the complete
component information on the target system, and currently
supports PCI Express Specs 1.0A, 1.0A+ECN, and 1.1.
