He says in the first email that when he puts the boards into an x86 box he can read them. The quick turns the ROM back on if the firmware is turning them off. In the PPC box the ROMs aren't being run so they would still be in power on state. I'd expect them to be readable in power-on state. You can dump the PCI config block in /sys with hexdump and see if the PCI_COMMAND_MEMORY bit is set. I was also unable to locate where in the kernel PCI_COMMAND_MEMORY is being set. It could be that it is set by the BIOS at boot on the x86 and not on the ppc. -- Jon Smirl [EMAIL PROTECTED] _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
