BIOS-Approved PCI Cards For Laptops 482

    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.

        The FCC regulations don't actually require what IBM does - the closest is a requirement that you not be able to use unauthorised antennae with an authorised card, which is the direct opposite of IBM's solution. The amount of the planet over which the FCC have jurisdiction is also fairly small compared to the size of IBM's market...
    • This is common of many newer IBM laptops. They will not boot with a mini-pci card other than the Cisco 350 series or Intel installed.

      It seems like a dirty trick, but I can understand why IBM would do such a thing. Think of it as certified hardware. IBM doesn't want to answer support calls asking "how do I set up a kwang-dong-fu mini-pci a/b/g card I picked up in china?"
      • by the way, mine is an A31. AFIK, the A, T, R, and X series are all the same in this respect. The only wireless cards that will work are the Cisco and Intel cards.

        I have no idea if this applies to non-wifi cards.

        Seems to me that if they don't want their computer to be compatible with PCI cards, they shouldn't advertise it as being compatible with PCI cards.

        But maybe I'm crazy.
        • Seems to me that if they don't want their computer to be compatible with PCI cards, they shouldn't advertise it as being compatible with PCI cards.

          These aren't PCI cards, they're mini-PCI--tiny little cards you have to open the case to replace. They're not that hard for a user to replace, but still I doubt this is a bullet point in the laptop advertisement in the way compatibility with PCI cards would be.

          --Bruce Fields

        • The last time I bought a laptop, none advertised that they were compatible with Mini-PCI cards. They all had the option of including factory installed Mini-PCI card, but none made any claim that it worked with anything other than the card that came with the system.

          I've very suprised that companies have begun to advertise otherwise, especially if they're required by the FCC to lock out untested wireless networking cards.

      Yes - this has pissed me off. I bought a 802.11b/g combo card to replace the 802.11b card in my Thinkpad T41. Little did I know that the laptop BIOS is deliberatly crippled, and refuses to boot with minipci network cards which aren't approved by IBM (often exactly the same cards, made by exactly the same manufacturers, but have a different hardware ID - a privelage you are supposed to pay 2x the price for).

      After a bit of research I managed to patch my BIOS to get around the problem - at least till I apply a BIOS update in the future.

      If I had know of this beforehand, I would have seriously considered a different laptop. The problem is there are no warnings, and the specs claim the laptop has a miniPCI slot - which would make one assume it is compatible with any card which follows the miniPCI standard.

Shortly after this is a set of PCI IDs, split up with 0s. The file is in little endian format, so the first byte in the file is the second byte of the ID. For instance, an IBM Pro/Wireless 2100 is 8086:1043 with a subsystem id of 8086:2551. This will appear as 8680431086805125. Make the modifications to suit your card.
    # Find the string EXTD. The 4 bytes after that are an additive checksum. When all the 4 byte blocks in the file are added up, they must equal 0. Change the checksum as appropriate. At some point I'll probably get round to writing a tool to do this.
    # Reflash your BIOS. Make sure that you use the /CS option to phlash16 in order to check the checksum.

    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.

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

      Because Airport is completely proprietary. I don't expect to be able to put a 3rd-party card in my iBook's airport slot because there are no 3rd-party cards that would fit. On the other hand, if IBM or anyone else advertises that their laptop has a [standard] mini-PCI slot, then it damn well better actually be a mini-PCI slot! And it should work with any [standard] mini-PCI card.

      (note: this is not Apple fanboyism -- I don't complain about the proprietary slot on the lid of of my Compaq laptop either.)
      • As others have posted, there is nothing proprietary about that slot. The original Airport slot was a standard PCMCIA slot, with a connector for the antenna. Airport was just a rebadged Orinoco. Airport Extreme is just a MiniPCI slot using a rebadged card (maker unknown). Apple doesn't tell you it's MiniPCI for just this reason - they aren't supporting anything else in that slot.

    It's too bad TFA doesn't say what kind of mini-PCI card. He probably bought some generic made-in-god-knows-where card from JustDeals or somewhere like that. Now, I'm an opponent of the direction "Trusted Computing" is going, but in this case there's something to be said for a manufacturer locking out shitty peripherals so they don't kill your system. It saves them one more support headache. Apple does the same thing. Sure, lot's of us Mac-heads bitch about it (myself included sometimes), but at the end of the day we can always brag about how plug-and-play Macs are. It looks as though PC manufacturers are following in footsteps of Apple again.

      Look, *all* the PC cards are made in the same giant sized factory called "Taiwan". I ran into a problem with an HP Netserver that HP blamed on my Crucial branded memory by saying only HP branded memory was good enough. Of course the solution ended up not involving the memory. Heck, HP doesn't own a memory fab; they just slap their sticker on whatever they get the best bulk rates on. In the article about the mini-PCI card, HP has no legitimate way to claim only thier PCI cards have to be used or the dang thing won't even boot. It's one thing to say 'we don't support it because you installed a third party peice' and it's completely different to actively prevent even trying.

    Which is what the blogger is referring to. Those cards, if I am not mistaken, are the kind of "built-in" cards that you can install, typically under the keyboard, but that you don't remove and re-install all the time. I think you are thinking of PCMCIA cards that you take in and out all the time. And in response to what the blogger is posting, he could remove the MiniPCI card and it would boot fine, and then revert his BIOS back to his old version (unless for some reason it had some VERY critical fix) and then put his card back in and simply not do the BIOS updates unless he really, really has to. But so basically, you don't have to worry at all, me thinks :)

    From TFA:
    I bought a Compaq/HP nx9110 a year ago, and recently upgraded my Mini-PCI Wireless card from non-OSS friendly Broadcom 11b to an 11g card. It's an HP Laptop. According to their marketing, I shouldn't have had to buy non-HP parts to be linux compatible.

    The HP BIOS for most models of laptop now have a whitelist of allowed Mini-PCI cards that can be installed in the laptop. If your new WiFi card isn't on the (very small) list of allowed cards for that specific model of laptop, then your laptop won't boot.

    Good reason not to purchase ANY HP/Compaq product from the Carly era, isn't it. Tough break there, but when you purchase something that's supposedly 'commodity', and then realize that it has a very, very short list of 'accepted' expansion options, you've done this to yourself.

    Personally, I'm a big IBM Thinkpad fan, plug in all type's of card's into them, and as long as I have driver support, I have no issues, be it XP, Linux, or any of the BSD's (of course, this changes with what hdd I plug in the laptop at the time).

      Bastard. Are you aware that all Thinkpads have Trusted Computing lockdown chips inside???

      Sure it's not causing any problems yet, but every Trusted Compliant system someone buys gives them that much more market share towards the point where they will be able to start utilizing that Trusted chip lockdown system. Sure the "unapproved expansion card" problem in the story can currently be overcome by reflashing your BIOS, but if any "security" software does make use of the Trust chip then you'll find yourself locked out of your own files if you attempt this fix. The Trust chip is designed to authenticate that the BIOS (and everything else) has not been "tampered with". As the Trusted-compliant market share increases you'll start seeing software start to use this chip. The software won't run at all on a computer without this chip, and it will only run on a computer with this chip when it's in "lockdown mode".

    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.

    Look, guys, Mini-PCI is not meant to be a route for user extensibility; it was meant to be a mechanism for the vendor to add individual cards to a standard motherboard. If you want to configure a high-speed a/b/g device, go through your USB ports.

    • However if you only have USB 1.1 (12mpbs) and Mini-PCI, an 802.11G (54mpbs) USB device is about as much use as a chocolate teapot.

    FCC certification is issued for the transmitter + antenna as a single unit. In the case of a Cardbus or conventional PCI wireless card, this is not a problem because the antenna is on the card. In a laptop with an internal mini PCI card the antenna is not on the card so the FCC certification is issued only for the manufacturers recommended wireless cards installed in the laptop with a chassis antenna. They include the white list in the BIOS to ensure that their FCC certification is not invalided by connecting an untested card to their chassis antenna.

    It sucks badly, but the current FCC rules are as much ti blame as the manufacturers are.

    The bios-level white list is an issue but that seems an undeserved cheap-shot against Broadcom.

      Fortunately, Linuxant has made their wrapper driver [] 64-bit compatible, so those of us with HP/Compaq notebooks running 64-bit Linux can use wireless, even though we have to jump through hoops to do so. (I've yet to get around to buying and setting up the driver personally.)

      I found out about the whitelist the hard way. Bought an expensive Atheros card, swapped it in, got the BIOS error message, got all

    Your Mini-PCI slot was never intended to be user upgradeable. Frankly, I always assumed they wouldn't be compatible between laptop vendors, models, or nescessarily even between two laptops of the same model that came off the assembly line on different days.

    If you want to upgrade to a better wireless connection, use a PMCIA card.

    Unlike a regular PCI add-in card, the miniPCI WiFi card(s) in question doesn't contain a PCI option ROM. Like VGA, SCSI or RAID cards, this option ROM configures the device before the OS loads.

    Since the option ROM isn't on the device, the ROM is stored in the system BIOS. When PCI option ROMs are stored in the BIOS, they are associated with the device's PCI "vendor ID" and "device ID". The "hack" described in an earlier post tells the BIOS to look for a different vendor/device ID (which hopefully is compatible with the embedded option ROM).

    Some network adapters require the option ROM for the OS drivers to work, and network booting requires the option ROM so the BIOS can use UNDI/PXE.

    This is a support problem from the notebook manufacturer. They only tested a few adapters, and only have room in the BIOS for one network option ROM. This has nothing to do with "trusted computing" or weird conspiracy theories. If the integrated card can't be upgraded, then USB or PCMCIA devices should be an option.

    Under 15 USC 50 2304 (Magnussen Moss Act []), HP has violated the terms of your warranty by disallowing you from using compatible hardware. When you purchased the laptop, one of the stated features was a PCMCIA slot - theimplied warranty is that it was interoperable with aftermarket componants which conformed to the PCMCIA standard.

    In short, you have the makings of a class action lawsuit on your hands. Get the to a slimy lawyer. They'll be in the phone book under "D" for democrat.

    I think alot of the confusion on this thread is stemming from the difference between mini-PCI and PCI and Cardbus (PC Card).

    To be very technical about it, PCI is the protocol, electical and logical that runs between on-board chips and plug-in cards. Mini-PCI, Cardbus and the most common flavor of edge connector PC plug-in card (called the "PCI expansion card" by the specification) all use PCI to communicate.

    In pupose and form factor, the three are very different.

    The PC plug-in card is used to provided user-accessible expansion capabilites to off-the-shelf PCs.

    Somewhat similiarly, Cardbus was intended as a laptop expansion slot for after-market upgrades. Again, user servicable.

    Mini-PCI was intended to allow laptop vendors to create an easy way to avoid the regulatory headache associated with getting UL (safety) testing done on every laptop with a modem. Modems are high-voltage devices.

    It turned out that mini-PCI was also useful for making other services (NICs and Wireless) easy to add to a base laptop design at build time rather than being designed directly onto the PCB. But this connection, was never meant to be user-servicable.

    In addition to the fact that there are no fewer than three specified and incompatible flavors of Mini-PCI, sometimes vendors even run non-standard signals through the mini-PCI connector, making them even more incompatible with each other (potentially hazardously so). All of this because they were never intended as user-servicable parts. If you want to expand your laptop, that's what PC Card is for.

    Wednsday May 19, 2004 I tried to post the progenetor of this to slashdot and got rejected. In particular I bought a top-of-the-line wide-screen HP (7130 ?) laptop with Media Center et al. It kept blue-screening so after two complete re-installs of windows I went to the HP site and got the BIOS update.

    After installing the new bios the box complained that my the build-in wireless board was not kosher ("authorized" is, I beleive, the correct word) and that I would have to remove the wireless board if I wanted the laptop to boot.

    I elected not to play...

    I returned it to Frye's for a complete refund.
