Win (7) Install for multiple T400 (with diff grafics)

#1 Post by jwege » Sat Jul 13, 2019 10:38 am


I purchased three refurbished T400 (including valid WIN Licenses) and was hoping they would be "identical" so I could re-use my (relatively complex) setup on each machine by cloning the HDD (or even swap it) and only "correct" the Win key and also, if one machine would break, use the spare one to replace it.

Unfortunately, that (tried swapping disks first) works only with two out of the three. Starting the disk in the other gets me a blue screen with LENOVOBUS.SYS (or similar) error - i could post a screenshot if that helps. I guess that it's the video driver as that is the major difference I could figure out so far (is there, by the way, any program that could do such a cross-machine-check?).

In earlier Win Versions, there were hardware-profiles that I guess could have solved the problem by making one "native" profile that does not activate some devices and use that to make one for the odd machine.

Win7 does unfortunately not support that anymore.

Does anybody have solved such an issue or can direct me how to make it? One (major) reasosn I purchased three was to have one as a "backup" machine, if one of the two "majors" would break ... but for now, this plan is corrupted by hardware.

Thanks in advance.

What you want should be possible.

I am not familiar with anything called LENOVOBUS.SYS. A screenshot of the exact error would help.

Does the problematic machine start OK in safe mode?

T400 has either fully integrated (Intel) or switchable (ATI/Intel) graphics.
The latter option has a BIOS setting to select this.
They need different drivers, so that may be your problem.
