How do I check my current BIOS version?

Myself and many others have explained this previously, but going forward don't assume anything on the ASUS SUPPORT pages for the T100TAx models... especially related to BIOS updates and what will work on your T100, this is a poor organizing effort by Asus. There should be separate pages for all T100 models, like the T100TAM, T100TAL, etc has. Yes this is the latest update currently but ONLY for the T100TAS not T100TA, nor T100TAM, nor T100TAL, T100TAF etc'.


If you want to be sure which BIOS version is running on your T100 model or your confused, make sure you check the current BIOS already installed on your T100. To do that, simply do one of the following through Windows, no need to restart and see BIOS, and remember this for future references for any upcoming BIOS releases,

1- Right-Click Start > Control Panel

2015-03-08 13_47_21-.png

2- Administrative Tools > System Information

2015-03-08 13_48_08-Administrative Tools.png

or if you want to access it easier/quicker,

1- Press WIN Key + R to Open 'Run Command'
2- Type 'msinfo32.exe' & Press 'Enter'

2015-03-08 14_18_46-Bios Version 213 (2015.03.05 Update).png

Once you have accessed, System Information, read on the right side under 'System Summary' for something like the below highlighted screen, it should clear all your doubts and tell you exactly which model you have and which BIOS is installed, TA, TAF, TAL, TAS, TAM, TAR etc.

Do not by any means use, EASY FLASH method, or force BIOS by any method on the T100 unit except WINFLASH which works, any other way/method/wrong BIOS you are likely going to brick your T100.

If you know your T100 exact Model and want to upgrade BIOS now, make sure to update your User Profile on these forums here as well, and refer to the sequence of the T100 Latest Model BIOS List for that particular T100 model here.

You can download the BIOS relevant updates from the official Asus Support & Drivers page for that T100 model, which can be found below.

Do Note, On the the below first page which is for T100TA, you will notice alot of BIOS Updates, since there is no separate T100TAS page, you will see it's BIOS updates stacked there too, however T100TA's current latest known BIOS is 313 dated 2014.09.23.


For T100TA & T100TAS (Why Asus Why??),
ASUSTeK Computer Inc. -Support- Drivers and Download T100TA

For T100TAM,
ASUSTeK Computer Inc. -Support- Drivers and Download T100TAM

For T100TAL,
ASUSTeK Computer Inc. -Support- Drivers and Download T100TAL

For T100TAF,
ASUSTeK Computer Inc. -Support- Drivers and Download T100TAF

For T100TAR,

If you have any other questions/queries, please comment on any other BIOS discussions thread accordingly in the respective 'T100 General Discussion forum section' or search the forums for BIOS discussions to find relevant threads.

Hope this clears out any confusion going forward, until Asus organizes the Support Pages properly, if you are really reading this then, organize properly by adding separate support pages for all T100 Models especially the T100TAS it should not be under T100TA. Goodluck & All the best on upgrading BIOS!

How do I update my BIOS?

-------------------------------------------------------------------------------------------------

*CAUTION*
Do not use the BIOS update method found at Asus.com service FAQ.

Here's a video tutorial that shows the proper way, using Winflash, to update your T100 BIOS.

Make sure after downloading the proper BIOS file for your model from the Asus service website, that you unzip it to a known location before proceeding.

Make sure you're plugged into power.

Note, there may be some update process occurrences where the updating "progress bars" will show on a full blue screen (with EasyFlash shown in the title) rather than the Winflash widget shield screen as shown in this video. If you see the update process screen with the EasyFlash title, this is a normal condition but...

REMEMBER...
NEVER EVER DIRECTLY USE EASYFLASH OR YOU WILL
BRICK YOUR T100 BEYOND EASY REPAIR.

FYI anything after 1:27 in the video is not necessary and in fact is discouraged to do.

The latest BIOS for the T100HAN is 214 dated 2015 Nov 24 on the Acer site; but internally has an Octoberr date! HAN appears to be the Acer designation for all HA models so don't worry about the "N".

Thanks to this forum I successfully updated my bios. During the auto reboot there was a concerning blank screen for several seconds. Be patient as this is Acer updating a driver--apparently necessary for this bios version. A dos-like text box finally appears showing this downloading, updating--and finishing.

Latest version is 216. Direct downloaded from Asus support website. Updated mine yesterday.

For T100 HA:
http://www.asus.com/latin/supportonl...Desk_Download/
In description of the new BIOS it says "BIOS 206 (T100TAN)"
Is this for T100HA?
Thanks

Welcome to the forum

A few points...
1) The TAN is a different model
2) The Asus website has been known to be wrong - both in descriptions and in linked files
3) The only 100% safe way to update the BIOS is via Asus Live Update

In other words, no-one can say and you do any manual BIOS update at your own risk.

Thanks janner43, I know that TAN it's a different model, but peterscm updated his Asus TF Book T100HA to 216 (But in the download page for T100 HA it says "BIOS 206 (T100TAN)") so thats why i'm confused. Thanks anyway. Will wait

If you download from ASUS Transformer Book T100HA | 2-in-1 PCs | ASUS Global

The description as below:

BIOS 206 (T100TAN)
Modify panel select rule

Notice：Please check in the BIOS setup for the correct BIOS file name of your Notebook PC. Please refer to FAQ:
BIOS Name of Notebook PC
https://www.asus.com/support/faq/114958

but once downloading the zip file, it is T100HANAS216.zip. File content is T100HANAS.216

I believe it is typo or Copy & Paste error on the description.

Latest version for T100TAF is 212 from 2015/10/15
