T400 BIOS bug in version 7UET79WW (3.09 ) [ Edited ]

[Izmi]

I have a T400 (2767AG8) and run Win 7 64. Before I've upgraded to Win 7, I've updated my BIOS to version 7UET79WW (3.09 ). As before the update, I made sure to disable various devices which I do not use to speed up my notebook start. Among the disabled devices are Intel AMT and the Ricoh CardBus controller. But Windows still detects these devices. This suggests that the BIOS does not correctly disable these devices.

Is the issue known?

Another issue:

I've disabled legacy ports in the BIOS. But today, Win 7 x64 recognized a serial port (as COM1) and an ECP parallel port (as LPT1)...

I have the same problem with a T400 upgraded to the latest BIOS V3.12.  Intel AMT is disabled in the BIOS, yet I still get a "PCI Simple Communications" device in Device Manager without a driver.  Even if I disable this device, I still am prompted for a driver each time I boot the computer.

Hi cjc1103,

Welcome to the forums!

I can confirm your observation. I have the same situation on my T400 with BIOS 3.12 under Win 7 x64.
