ASUS Transformer Book T100

Console OS > Wiki > Devices > ASUS Tranformer Book T100


Device Description

The ASUS Transformer Book T100 is a family of 2-in-1 convertible tablets that support a physical keyboard dock. Some keyboard dock models include a 500GB Hard Disk Drive (HDD).

There are several variants of the T100 family. Our goal is to eventually provide full support for all T100 family variants.

This tablet line should not be confused with the ASUS Transformer Book T300 family which appears similar externally, but is powered by an Intel Core processor.


BIOS

Having the latest firmware (BIOS) for your machine is an essential part of making sure Console OS with Android works well.

There are several variants of the T100 Series. Each has a BIOS update available for it. Press F2 rapidly while booting the device to check its BIOS. You also can alternatively hold the volume down key while booting to access UEFI/BIOS settings.

  • For T100TA models, you must be running BIOS 314 or later.
  • For T100TAF models, you must be running BIOS 212 or later.
  • For T100TAM models, you must be running BIOS 206. Do not use BIOS 208 as it is actually older and for the T100TAN.
    • The T100TAN is only sold in China, which our staff does not have access to.
  • For T100TAS models, you must be running BIOS 214 or later.
  • For T100TAL models, you must be running BIOS 213 or later.
  • For T100 Chi models, you must be running BIOS 206 or later.

Please note: We have not fully tested with the T100 Chi. It may need some DPI corrections due to its HD display. We welcome feedback on the Console OS Forums.

Updating the BIOS

ASUS only provides a method to update the BIOS from within Windows. They do not have a path for updating the BIOS from Linux, or Android. We strongly recommend updating the BIOS before making any attempt to install Console OS.

We encourage people to send feedback to ASUS, asking for them to provide OS Agnostic flash drive BIOS update methods - as most PC makers now do.

If you have upgraded to Windows 10, you may have difficulty updating the BIOS using the Windows flash tool that ASUS provides. To fix this, you need to install the ATKPackage (typically under the ACPI tab) from support.asus.com.

From there, download the Windows BIOS Utility (available on the same site) and applicable BIOS version. Because of the tablet's design, you should backup all data before installing. If the BIOS update fails for some reason, it may not be possible to extract data from the eMMC solid state drive integrated in the system.

Installation Notes

Known Issues

  • If Wi-Fi does not work properly, restart the device. This tends to occur most on the first reboot when switching between Windows and Android without a full shutdown. We suspect ACPI tables in the BIOS are not cleared fully during a warm reboot.
  • Camera is not currently functioning

T100TA BIOS Issues

There is a known issue with the T100TA BIOS in that it will not always populate the list of available boot devices immediately. Console OS is pushing the limits of what BIOS makers normally test for - since 99% of people simply boot into Windows.

This most commonly may surface as a problem if you have Windows installed on the HDD keyboard dock, and Console OS installed on the eMMC SSD. It may not be possible to select the eMMC as a boot option - because the HDD dock fills the maximum list limit.

This also can surface as an issue if the HDD dock takes too long to spin up, only resulting in the eMMC to list as a boot option - even if Windows or Android have been installed properly to the HDD keyboard dock. Note: Not all keyboard docks for the T100 have a built-in hard disk drive.

There are two workaround steps you can take if things are not working right.

1) On the boot device selection area of the BIOS, if you do not see the internal SSD, but see three HDD boot targets, this is because the boot selection menu is full. To work around this, simply power the device down, detach the HDD/keyboard dock, and then reattach it when the device has finished booting.

2) If you do not see the HDD as a boot option, hit Save Changes and Exit in the BIOS, then rapidly hit F2 until the BIOS re-loads. This is caused by the BIOS not waiting long enough for the HDD in the keyboard dock to spin up, and thus does not always list it as a boot option.

We welcome you to report this issue to ASUS by sending them a length to this page. Strength in numbers.


Installing Windows to Keyboard Dock HDD, Console OS to SSD / eMMC

In this scenario, you have an ASUS Transformer Book T100TA and wish to install Console OS exclusively on the tablet’s internal SSD, and simultaneously deploy Windows 10 on the optional HDD dock.

To do this, you need the following:

  • An ASUS Transformer Book T100TA with BIOS 314 installed
  • ASUS Transformer Book HDD-enabled Dock (not all keyboard docks for the T100TA have a hard disk drive bay)

BIOS 314 Update Note:

If you get an error attempting to update the BIOS (particularly after upgrading to Windows 10), you may need to follow this guide: http://www.transformerforums.com/forum/asus-transformer-book-t100-general-discussions/41897-how-flash-bios-if-you-get-cannot-allocate-buffer-store-bios-file-error.html

Perform the following steps:

1) Install Windows 10 to the internal SSD/eMMC drive.

2) Once Windows 10 is installed, perform a second USB HDD installation of Windows 10. This second installation should activate automatically via Digital Entitlement. You will need to use a Windows To Go installation tool to install to the HDD dock. WinToUSB is our recommended tool for this task.

3) Install Console OS, erasing the internal SSD. Do not leave Windows 10 installed on the SSD, in this scenario. That could violate Windows licensing and result in both Windows installs being deactivated. It is strongly recommended that you remove the HDD dock for this step, to avoid accidentally installing Console OS to the HDD dock.

4) To boot between OSes, tap F12 during startup. Alternatively, you can rapidly tap F2, and switch over to the boot tap. This is necessary because the Console OS installer cannot currently detect Windows volumes on USB drives - so it cannot add a boot menu item directly. Hence, you have to use the machine’s built-in OS selector during booting.

Important: Once you have booted Windows 10 from the HDD keyboard dock, do not remove the keyboard dock while the machine is running. Doing so could cause data loss. Only remove the keyboard dock while the machine is powered off. Currently Console OS does not mount NTFS volumes, so while running Console OS, you can hot swap the keyboard dock when desired.
