I replaced the PCI card with this new board, but it seems the board is listed but otherwise ignored. The only trace is in lspci output. There isn't a list of devices in the other side of this PCI-to-PCI chip. # lspci 00:01.0 SCSI storage controller: Adaptec AIC-7880U 00:02.0 SCSI storage controller: Adaptec AIC-7880U 00:03.0 PCI Bridge: Netmos technology Unknown device 9250 (The card vendor and product are IDs 9710:9250.) When I plug the card on an i386 machine, it is recognised since lspci display the card and all three devices present on the same card (devices accessible via the PCI-to-PCI bridge). All these devices are available to udev, so udev start all relevant drivers. I started checking my kernel config. Do I have to activate any specific CONFIG_?? option in order to use such a card (beside the driver for all devices). Actually I have: CONFIG_HW_HAS_PCI=y CONFIG_PCI=y CONFIG_MMU=y # CONFIG_HOTPLUG_PCI is not set while on i386 I have: CONFIG_PCI=y # CONFIG_PCI_GOBIOS is not set # CONFIG_PCI_GOMMCONFIG is not set # CONFIG_PCI_GODIRECT is not set CONFIG_PCI_GOANY=y CONFIG_PCI_BIOS=y CONFIG_PCI_DIRECT=y CONFIG_PCI_MMCONFIG=y CONFIG_PCIEPORTBUS=y CONFIG_HOTPLUG_PCI_PCIE=m # CONFIG_HOTPLUG_PCI_PCIE_POLL_EVENT_MODE is not set CONFIG_PCI_MSI=y CONFIG_HOTPLUG_PCI=m CONFIG_HOTPLUG_PCI_FAKE=m CONFIG_HOTPLUG_PCI_COMPAQ=m # CONFIG_HOTPLUG_PCI_COMPAQ_NVRAM is not set CONFIG_HOTPLUG_PCI_IBM=m CONFIG_HOTPLUG_PCI_ACPI=m CONFIG_HOTPLUG_PCI_ACPI_IBM=m CONFIG_HOTPLUG_PCI_CPCI=y CONFIG_HOTPLUG_PCI_CPCI_ZT5550=m CONFIG_HOTPLUG_PCI_CPCI_GENERIC=m CONFIG_HOTPLUG_PCI_SHPC=m I am using kernel 2.6.18 on both machines, as shipped with Debian stable.
