If you are paying out-of-pocket like me, I would suggest the el-cheapo route. I paid $50 to PCI SIG, and receive a printed copy of PCI 2.2, and a CD-ROM containing -all- the PCI specifications. http://www.pcisig.com/ > I believe LinuxBIOS does a good job with the PCI resource allocation. > Possibly imperfect but good. Not nearly everything needed to be fully compliant, and compliant basically means bloat. I would prefer to leave linuxbios PCI setup as-is, for current setups -- but with the option to turn it off if "freebios" is present to do a better job. > The core LinuxBIOS needs to contain all of the motherboard specific > information and either provide it implicitly by setting up the hardware > correctly, or explictily by exporting it in the LinuxBIOS table. I disagree for one case, the "freebios" case. If we are booting linuxbios -> freebios -> linux kernel it is silly to include all options for all hardware, in the "freebios" piece. Thus, one must provide a custom "freebios" image for the specific hardware you are running, or a subset of systems. Jeff -- Jeff Garzik | Building 1024 | MandrakeSoft | Choose life.
