Introduction
Express Cards are like PCMIA cards but much faster.They come in two sizes one larger and one smaller. You can plug a card made for a smaller slot into a bigger slot but not vice versa. Currently there are few cards in this format.
see http://en.wikipedia.org/wiki/Expresscard for more information.
Installation
The installation of a ExpressCard should be trivial. The default kernel has support for "PCI Express Hotplug driver". The kernel option CONFIG_HOTPLUG_PCI_PCIE should be set and you should have a module called pciehp in your system.
Kernel Module
sudo modprobe pciehp pciehp_force=1
Troubleshooting
Load the module with the option "pciehp_force=1", otherwise some errors are generated, because the ACPI firmware lacks support for the _OSC function:
[ 290.828000] pciehp: HPC vendor_id 8086 device_id 27d0 ss_vid 0 ss_did 0 [ 290.828000] Evaluate _OSC Set fails. Status = 0x0005 [ 290.828000] Evaluate _OSC Set fails. Status = 0x0005 [ 290.828000] pciehp: Cannot get control of hotplug hardware for pci 0000:00:1c.0 [ 290.828000] pciehp: HPC vendor_id 8086 device_id 27d2 ss_vid 0 ss_did 0 [ 290.828000] Evaluate _OSC Set fails. Status = 0x0005 [ 290.828000] Evaluate _OSC Set fails. Status = 0x0005 [ 290.828000] pciehp: Cannot get control of hotplug hardware for pci 0000:00:1c.3 [ 290.828000] pciehp: PCI Express Hot Plug Controller Driver version: 0.4
