T400 BIOS and virtualization

I know this topic has been opened before but I have not found any answer. I have the T400 and I can not enable the virtualization on it. I have sees some people hack the BIOS but for different models, is there any success with the T400 ?

Re: T400 BIOS and virtualization

There shouldn't be any hacking necessary.  I've been able to turn on virtualization on my T400 in every BIOS I have run on it.

 

It's there in BIOS->Config->CPU-> Intel Virtualization Technology and Intel VT--d feature.

 

I'm running BIOS version 7UET86WW(3.16).  What BIOS version are you running?

I have 7UET66WW (2.16) and the two settings options are disabled

 

I have just updated to 86, still the vt-d and virtualization are disabled and can not be selected.

Have you done a full power off power on cycle since the BIOS update?  ISTR that just a reboot doesn't quite do the job.

 

[edit] The power cycle requirement may be for _after_ you enable VT, which you currently can't do.  Worth a try.

 

Also, what processor do you have?  I would be quite surprised, but there may be some processors that don't support virtualization (very unlikely) or maybe a BIOS bug that relates to certain processors.

 

Have you called support about this?

 

[more edit] Are you able to change _other_ BIOS settings, or are they also grayed out?  Perhaps you have a password option set that lets you view options but not set them?

Re: T400 BIOS and virtualization

I found the problem, there is a supervisor password set.

What's DOS?
