Whatabout a quick-and-dirty DOS version of DeepSleep just for TP600E with fixed port numbers? Sharedoc, I've uploaded a DOS version of the DeepSleep utility to http://home.pacbell.net/wmarcusm/deepsleep/ It is pretty beta level. I've only tested it under PC DOS 7.0 on my TP600e 2645-55U. It only lo...

Shardoc,

I found some code to do the PCI device lookup under DOS, so I'll post a DOS version in the next day or two.

Difficult to say how many legacy Win98 users there are out there. Whatabout a pure dos DeepSleep utility that can be inserted in autoexec.bat in Win98? To my understanding this would be quite simple extracting the core part of the SpeedStep driver. The code to do the DeepSleep call from DOS is only...

OK, I tried to install for Win98, but it fails to open \system32\drivers for copying file Sharedoc, Yes, as I suspected. Even if the OS directory structure were the same under win9x/win3x, the piix4.sys driver would not load under win9x/3x :-( Are there a significant number of folks that would stil...

wmarcusm, Could you share the piece of code you wrote?? That would help this TP600e community a lot. - ProtoColD ProtoColD, et al, I've posted the winxp/2k version of the DeepSleep code at: http://home.pacbell.net/wmarcusm/deepsleep/ If you have winxp or win2k installed on your thinkpad 600e you ca...

Wmarcusm, I wonder if CPU overheating related throttling in 600E has been implemented using the same DeepSleep/BX Southport mechanism, since it seems to trigger the higher SS speed as well. My TP600E uses the original Windows98 installation that came with the laptop. So it is prior to SE. Sharedoc,...

Wmarcusm, Wow, thanks for bringing eventually light to the SpeedStep issue! Software initiated DeepSleep: What a great idea! Newer came to think of that before. I always assumed that the state transitions were driven by platform hardware signals. Is there any danger of left hanging there in DeepSle...

[quote="Sharedoc"]Brokencase, You are right. I admire your logical deduction capability. Let's try to find solution to SpeedStep. Now this what I have found out sofar. Intel has a specific chip that controls SpeedStep. It propably works in a way of a special I/O device containing internal registers ...

You need to disassemble the laptop and take off the motherboard. At the lower side there is clock generator (IMISG577). Equivalent spec can be downloaded http://www.standardics.philips.com/products/pck/pdf/pck2000.pdf Please check pin#25 (sel100/66) when power is on: 0V=L=66MHz, 3,3V=H=100Mhz. If i...
