Lenovo shop here, have had to do BIOS updates on the Twist, Yoga, L440, and T540p to resolve issues with PXE, sound, and HDD issues.
All of these are in the past 2 years.

For example though, the Latitude E6430s have a bug with UEFI and secure boot on a docking station, in which the video doesn't show up until the login screen. This means bitlocker, or system passwords would sit there waiting, and the user didn't even know. The latest BIOS for that model fixes it. I also noticed the E6440 does the same thing. So there could be other fixes that I might not need at that time, but they're still problems none the less, so is rather have the fixed rev than to face possible problems later on.

I did that back in the old days (3.1,95,98, NT, maybe 2000). But I “never” update the BIOS now a days unless there is some functionality that is needed …. Which never happens.

But something happened a few months back where I had to switch so that the bitness of WinPE matched the OS being deployed. I think it was caused by driver injection problems, but I can’t remember exactly. I feel like I read the advice on DeploymentResearch.com<http://DeploymentResearch.com>, but I can’t find the post now. Anyway, matching the bitness fixed my problem. Now I am in a little trouble with this because I would like to update the BIOS on Dell computers during OS Deployment and it looks like Dell only has 32 bit versions of the BIOS updates available. I think I cannot run a 32bit executable to update BIOS while I am booted into a 64bit WinPE version. I could briefly boot into a 32bit WinPE boot disk while updating the BIOS and then continue on in WinPE 64bit, but the only two options for rebooting are into the Full OS or into the WinPE boot disk assigned to the Task Sequence. Is there a way for me to reboot into a specified WinPE image, update the BIOS, and then reboot back into the WinPE that is assigned to the task sequence? Is there a way out of this problem? One thing I can think of would be to do the BIOS update as a prehook before the real Task Sequence starts… ________________________________ Notice: This UI Health Care e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C. 2510-2521, is confidential and may be legally privileged.
