T61/X61 SATA II 1.5 Gb/s cap - willing to pay for a solution

An experienced BIOS modder doesn't need a HOW TO from me. He just unpacks the modded BIOS and compares it with the original one.
And what do you mean saying "to continue"? I'm almost sure that there will be no further BIOS updates for such old Santa Rosa machines. All bugs were fixed a long time ago. If BIOS update with serious changes is released, then I'll modify the mod but Tivoli OS issue isn't the reason to update the package (from my point of view).

 

Hi middleton,

Thanks for your response!

While I agree with you for the most part, to be fair, there really hasn't been updates to the T61 series in a while. IBM/Lenovo has been known to taper off with rarely releasing newer BIOS'es for Thinkpads as they get older; and by now, this generation is pretty much deemed as a "legacy" series.

Seeing that it's been updated to version 2.29 and not 2.28, albeit most likely due to internal testing, what I am hoping for and have seen done in the past are undocumented "under-the-hood" changes. The biggest issue for the T61 series has been DPC latency issues for a lot of users and I am hopeful that they have been addressing it silently with this update.

I have donated money for the initial modification before and I would be willing to pay for an update again

Please let me know your thoughts on this and again, THANK YOU!!

 

I've never had a ThinkPad, so the information that lenovo doesn't mention all changes in the official change log is news to me. In this case, there is a real chance that version 2.29 includes some useful fixes "under-the-hood".
OK, I'll update T61/T61p patch (and X61/X61s/X61 Tablet too) next week.

 

Thank you middleton!!

I will be sure to donate again!!

Thanks again and again and again!

 

please explain what those are

 

Hi miro_gt,

For more information, I would suggest starting HERE.

And one of the tools used to monitor DPC Latencies can be found, along with more information, is HERE.

Hi,

please hope someone could help me.
I flashed the bios with ctrl+fn swap.
But this is not realy good for me.So i like to switch back.
How could i do that?
Flashed orginal Bios, no chane.
Please, help me.
Big thanks
Bye

 

Make sure you flash back to middleton's non-CTRL+FN swapped BIOS and then once completed after a successful reboot, go back into the BIOS and press F9 to load all setup defaults, then press F10.

I'm not a 100% sure, perhaps middleton or soemone else can help answer this, but I don't know if the ECP gets wiped out and re-flashed as well, which from my understanding, is where the keyboard is mapped out.

See if that helps and let us know.

 

Read here how to get back the original FN-CTRL layout. Create flash.bat in BIOS update folder (version without CTRL-FN swap) and run it as administrator.

 

As you know, recently lenovo released new BIOS for several "old" ThinkPads. Here are my patches based on the latest official BIOS-es:

ThinkPad model : machine type​	BIOS​
T61, T61p R61 (14.1" widescreen with IEEE 1394): 7732, 7733, 7734, 7735, 7738, 7742, 7744, 7751, 7753, 7754, 7755 R61i (14.1" widescreen with IEEE 1394): 7732, 7742	2.29-1.08
X61, X61s	2.22-1.03
X61/X61s SXGA+	2.22-1.03
X61 Tablet	1.25-1.02

UPDATE: these patches were successfully tested and became recommended ones. You can download them from page 8.
