The initial PCI specification permitted a maximum clock rate of 33 MHz allowing one bus transfer to be performed every 30 nanoseconds. The PCI specification defines two types of connectors that may be implemented at the system board level: One for systems that implement 5 Volt signaling levels, and one for systems that implement 3.3 Volt signaling levels. In addition, PCI systems may implement either the 32-bit or 64-bit connector. Most PCI buses implement only the 32-bit portion of the connector which consists of pins 1 through 62. Advanced systems which support 64-bit data transfers implement the full PCI bus connector which consists of pins 1 through 94.I have seen reports of this problem affecting a T41p, T43, X40, R31, X31, and T30 but I do not know how far back this problem goes or if there are exceptions. Will be finalized into some user-friendly thing hopefully.I am unsure about which models this applies to. 15 How many people have really successfully taped over a MiniPCIe PiNBasically solved here. 11 Other issues with unauthorized cards 4 Confirmation - patch not working on T43 3.3 Volt add-in boards include a key notch in pin positions 12 and 13 to allow them to be plugged only into 3.3 Volt system connectors.Anyone have a list?There were several edits to the previous page to the effect that "this didn't work for my T43". Now I need to know what vendor and device ID strings to use when I flash the card's BIOS. Seemed like there was, so I bought a mini-pci-to-PCI adapter and installed the card(s) in my desktop. When I discovered that it would not work in my Thinkpad I came to this site to see if there was a fix. - Kevinoid 05:44, (CET)I have a R40 model 2681-K9G that came without any mini-pci card so I bought a Intel PRO/Wireless 2915ABG mini-pci card for it.
I tried several cards (some working without patch in another thinkpads (t40, t42, x40), but no success.- Jap 09:50, 13 June 2006 (CEST)I'd like to send out a BIG FAT WARNING that 'hotplugging' the mini-PCI card can easily lead to frying the system board, mini-PCI bus, or both. - Kevinoid 05:44, (CET)I can confirm, that a "nvram/cmos" patch is not working on my T43, exact type 1871-A62. If anyone can confirm or deny this statement, please do so (and possibly ask on the ML for solutions if it does not work for you). I applied the C-Patch from here. Bought an Intel Wireless card since the linux drivers for the madwifi are crap. - LJSBrokken 13:01, 20 July 2006 (GMT+1)I tried this on a Lenovo Z60t. However, somewhere it must have gone wrong because now the laptop hangs immediately when the IBM/Intel boot logos appear. Pang game free downloadAfter a few secons grub starts with its default entry (Gentoo Linux). At this point I can't use the keyboard, the key symbol is still displayed in the upper left corner. Even if I don't put my finger on the sensor, it continues with GRUB. ![]() Mini Pci Card Pin Count Update The SubsystemOn the other hand adding a new set of vendor ids in the madwifi driver isn't a big deal either. Have a look into the source code comments at the begin of ath_info.c. Moral of the story is be careful with ath_info.You should be able to use ath_info _without_ the madwifi driver use some low level pci tool to manually configure the card. The card is basically bricked, unless I find time (ha ha) for some kernel hacking. I *still* got the warning message, and now the ath driver doesn't pick up the card, so I can't use ath_info. I made a mistake at this point and didn't update the subsystem vendor id / subsystem device id, just the primary pci vendor and device ids. Ikea kitchen planner mac plugin(yak - )I've added a new section called "Problem with WiFi LED". Changing PCI-ID is quite easy, see this (also helpful: Patching the EEPROM section of Ipw2200 article). However, I've found a way to fix this: see here. (yak - )It does the same for my r40 and not IBM intel 2200, I think that the led would work only if the PCI ID of the minipci card would be changed to IBM, but i dont know excatly how to do this, I just remember seeing it somewhere (kajencik - )I now know that someone changed the PCI-ID of my Intel 2915ABG card so it looks like an IBM one. If this is common to all non-authorized cards, this wiki article should mention this. A little note - the r40e obviously dont have an antena - i'll have to get some, but its working even without antena for short range indoor (the accesspoint is about 3 meters away)I'm not sure if this is common but my Intel Pro 2915ABG (not from IBM) works on my T41 (both from eBay so some patch was probably already applied) except that the WLAN LED on the laptop stays off all the time. modifying the PCI-ID of the wlan card for atheros: Does anyone know if there is an incompatibility issue with Atheros card in the R31?I'm just trying to fix the 1802 error, but several links indicated in the useful solutions section don't work any more: What I shall try soon is to swap the 5005G with a friend for a Realtek card from his laptop. (yak - )I have the BIOS hacked in my R31 so it boots with the unauthorized card and XP picks it up, but XP will randomly lock up with the current card (Atheros 5005G) I have tried another of the same chipset and it does the same thing. The antenna cables are long enough to reach if you (carefully) untape them from the plastic cover sheet. The X61s doesn't seem to check the second Mini PCIe slot (near the audio sockets) against the whitelist. I'm running Ubuntu Intrepid. But is anyone able to retrieve equivalent links or to upload the live cd again? - Jwollbold 22:03, 6 September 2008 (CEST)I bought a non-IBM Intel 4965 from eBay and was able to get it running without twiddling the BIOS. That seems to be easy and has worked for t40, ubuntu and a broadcom pci card, according to the list of successful BIOS modifications (in this case only the CMOS has to be changed, which is more secure). I recall that others have reported the BIOS complains if there are two. (I can come up with some photos if it helps).This disables the killswitch, but it never worked with the original Atheros card anyway, so it's no big loss to me.Interestingly, I had no problems running the machine with two WiFi cards. I got around this by taping over pin 20 with a tiny piece of a post-it note. I assume that it's only wired to the first PCIe slot. Tested on X230, taped pin 20 and tried both half-mini-PCIE and WWAN mini-PCIE slots, didn't work - MagicFab 17:43, 9 January 2013 (CET) Anyone should thoroughly research a software based solution for your hardware/unsupported card combination before attempting to tape over a MiniPCI-e PiN. The task itself is frustrating and should be undertaken with a new, sharpest of razor blades, a good magnifier glass/visor in a well lit area on a stable surface. The PiNs are smaller than the tip of a pen, even a ThinkPad stylus is wider. ![]() With regard to how difficult this is-I managed with just a role of cellotape and a pair of scissors. Before, it was detected but could not connect. Taped pin 20 and after that the device worked.
