Hello again, Just to clear up a few things. I have been informed that I was mistaken on a couple of the configuration items below. The kernel is not Debian - that's the development system. The kernel is 2.4.22 w/ linuxppc-2.4.22 & rtai-24.1.12 patch files applied. Some cleanup done to clear build errors. Compiler is HardHat-2.95.3
Thanks again!! -John ----- Original Message ----- From: "John Manby" <[EMAIL PROTECTED]> To: <linuxppc-embedded at lists.linuxppc.org> Sent: Wednesday, January 21, 2004 10:39 AM Subject: PCI resource conflicts > > Hello, > > I looked into the archives and found where several others have asked this > question, but I couldn't find where anyone had received a sufficient > solution.
