Lenovo T430/T530/W530 etc. (30'series with IVY bridge)Pay attention for solving TOLUD

Recommended Posts

Hello fellow Lenovo owners,

I've started at tech thread over at the Lenovo forums, to ask them for a bios update to solve the TOLUD problem.

Atm. i'm running the latest bios (2.59), and unfortunately my PCI bus memory adress says: DFA00000 - > TOLUD 3,5 GB = no room for eGPU with 4GB+ RAM.

I've tried to override DSDT aswell (Windows 7, 64 bit), but it all turns out to BSOD's at boot.

I've stumbled across another thread on lenovo forums, which gained the right attention for the Lenovo staff to update the bios's on the X230 and T230 models: http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/X230-expresscard-adressing-eGPU/td-p/792909

Therefore I hope it will be possible, for the T430/T530/W530 owners to receive the same solution. But for that I need the Lenovo staffs attention, ad therefore, your help.

head over to my thread at: T430 expresscard adressing (eGPU) - Lenovo Community

and leave a comment, if you would like to see a solution in the future.

Hopefully in the end, it will be something the bios tech guys pay attention to, in the future bios designs.

Thanks in advance :)

Earlier this month, Lenovo released a new bios for the X230T, version 2.60. Does anyone know if this new bios will allow better egpu implementation? There were problems with memory allocation, effecting TOLUD and limiting ram to one 8GB stick instead of two. Anyways, thought I'd give a heads up about the new bios. Maybe someone can confirm if the issues are fixed now?

[edit] Well, did the update and checked device manager - still at 3.5GB TOLUD for me.

      Hello, I just got my exp gdc dock (Beast) and my GPU (ASUS GTX 1660 SUPER) and it seems like the bios "blocking" the egpu.
      Can someone give me a mod?
      Thanks

      Hello !
      I tried a tutorial on the forum to remove the supervisor password on a X260 thinkpad but the winbond 25Q128FVPQ chip is not recognized with the programmer CH341A and ASprogramer (does not detect automatically and not manually). Plugged into the motherboard with a soic8.

      Can you help me with detection?
      Can I find the password with the software or do I have to write it?
       
      Thank you so much !!!

      To install the unlocked bios, I prepared and booted a freedos usb. I start the installation by typing flash.bat but every time I get the following error: Error 28: Protected Range Registers are currently set by BIOS, preventing flash Access. Please contact the target System BIOS vendor for an option to disable Protected Range Registers.
      How can i solve this problem ?

      Hi!

      I would love to have my BIOS modded to disable the wireless whitelist.
      I tried to do it myself (dump BIOS from chip, disassemble, locate the reference to the error message "Unauthorized Wireless network card is plugged in..." memory address and modify the condition in the binary file so not to "land" in the infinite loop) but I couldn't dig to anything meaningful I could easily change.

      Laptop: Lenovo ThinkPad S440 (TYPE 20BB-S00400)
      BIOS version: 73ET71WW (1.71)
      Original WiFi/BT card: Intel Wireless-N 7260 (7260HMW BN) (vendor: 0x8086, device: 0x08B2, subdevice: 0x4262)
      Target WiFi/BT card: Broadcom BCM94352HMB (I haven't received it yet, waiting for delivery)

      Manufacturer BIOS download: bootable ISO, updater for Windows
      My BIOS dump (using CH341A SPI Programmer under Linux): http://www.mediafire.com/file/mn0gfr9ext7yqrn/S440_73ET71WW.bin/file
       
      Thanks!
