We had a similar problem with our 4 processor machine, and Kevin Van Maren who was working on the support for the NX chipset suggested that this could be harmful in the SMP case, so it includes some code which reduces the number of PCI busses to be somtheing reasonable - see fixbushigh_450nx in sys/pci/pcisupport.c. The Dell BIOS guy who I eventually got in contact with said he had spoken to Kevin about it, and that the 255 value was "correct", but he couldn't say why because of an Intel NDA. The code which figures out the bushigh stuff for your machine probably needs a similar kludge, unless someone can say for certain that it isn't harful for the SMP case. David.
