PCMCIA cards do not work on Dell Latitude e5510 under Windows XP. Works fine on Windows 7. Cards are recognized by Device Manager but do not work correctly. For example, CF adapter does not recognize when a card is inserted and network card is unable to obtain an IP address.

Other systems that may be affected:

Latitude E4310
Latitude E5410
Latitude E5510
Latitude E6410
Latitude E6410 ATG
Latitude E6510
Dell Precision Mobile WorkStation M4500

Wow you were really quick to ask and answer your own question... – JNK Sep 8 '10 at 19:47

Locate the following key in regedit:


Add a REG_DWORD named IrqRouteToPciController and assign a value of 8.

Reboot and try PCMCIA again.

Excellent. Thanks, Rich! – Rich Sep 8 '10 at 19:45
This did nothing. I have a E5520 running XP, and if you look in the device Manager, under PCMCIA adapters, it has one entry, but it's a Generic Cardbus Controller. – user94518 Aug 17 '11 at 18:09
