BIOS-Approved PCI Cards For Laptops

Posted by timothy on from the to-benefit-the-consumer dept.

derek_farn writes "First there were printers that would would only work with vendor annointed ink cartridges; now we have laptops that will only boot with vendor annointed PCI cards. Keeping a list of approved PCI cards in the bios is one way of ensuring that customers renew their maintenance contracts. How else are they going to be able to plug in a PCI card released after the last BIOS update?" My HP laptop is several years old; can anyone confirm this?

  1. IBM Thinkpads are the same way by explorer · · Score: 5, Interesting

    My older Thinkpad T40p has a whitelist, too. Luckily the Cisco 350 mini-PCI card I needed to connect to the corporate wireless LAN is on the whitelist. IBM actually sells the Cisco card with an IBM part number.

    But forget trying to buy a random 802.11 a/b/g card and plug it in.

      From what I've read this is because the FCC approval for the wireless is the combination of the card and the antenna (which is built into the screen). Obviously it's not really in IBM's (or any other manufacturer) interest to test every possible wireless card with their kit. They probably lock them to keep the FCC happy.

  2. HP is (in)famous for this sort of thing by n6mod · · Score: 5, Interesting

    I have an old NetServer LPr that I use as a Debian server. It's built like a tank, and has been fairly reliable, save for one issue:

    Since I got it (used), it always printed a warning that non-HP DIMMs were detected, and HP's on-site warranty didn't cover problems caused by non-HP memory.

    Then two of the DIMMs failed, so I popped the lid.

    You guessed it. HP memory.

    At least the motherboard was kind enough to turn on a flashing light next to the bad DIMMS. (Seriously)

  3. Incompatibility List? by DavidNWelton · · Score: 5, Interesting

    There is a list of hardware that is not very Linux friendly here: http://www.leenooks.com/ - perhaps this stuff would make a good addition to the list.

  4. Mini PCI was never intended for end users by Anonymous Coward · · Score: 5, Interesting
    Intel Technology Journal:
    The PCI Express Mini Card specifically targets addressing system manufacturers' needs for build-to-order (BTO) and configure-to-order (CTO) applications rather than providing a general end-user-replaceable module. This form factor has characteristics more typical of an "embedded" application including the platform integration of the media interfaces such as communications connectors or wireless antennas.
    Cisco MPI350 FAQ:
    The Cisco MPI350 cannot be sold as an aftermarket adapter because ... Regulatory certification is based on the MPI350 being coupled with a particular antenna. Although modular regulatory approvals are available, they only apply to the original equipment manufacturer (OEM), who is responsible for embedding similar antennas in different devices. Modular regulatory approval does not eliminate the restriction on aftermarket sales since the end user might embed the adapter in devices with unapproved antennas.
    Basically, these companies are using FCC regulations as an excuse for limiting Mini-PCI cards (not just on these particular laptop models, but all Mini-PCI cards in general) to OEM installation only.

    There's an easier way. See this page for a utility that disables the check without requiring BIOS modification.
