I tried it today (3 december 2018). I was updating my EeePc 1015CX using its dedicated Asus EZ flash utility from a very normal 2Gb Fat 32 USB pendrive; and everything went fine. Now EMT64 support is listed both in Bios and using the lscpu command.
I am very grateful because I really like my small Netbook. I have been treating it very good in the last 5 years, so it's in excellent conditions. Unfortunately Skype (Microsoft) has dropped its linux i686 support, making it impossible to use it.
Thank to this mood I was able to boot a 64 bit kernel and soon I'll get the right version.
In a word you gave me the opportunity to enjoy my nice little PC for some other years!
Thank you!
Almost 4 years after you posted this and someone (me) still finds it useful!
Thanks! It will bring new life to an unused eeePC I had laying around.
I join all thanks sent by users to the person who posted this post! This mod is installed on Asus 1011cx. Everything works fine! No complaints. Many thanks!

Dear Messiah, thanks for the modified BIOS. I installed it on my little Asus 1011CX without any problems. Delivered Windows 10x64 1809 (replaced HDD with SSD). The system responds well. Now busy looking for a driver for the Intel GMA 3600.

For some reason LibreElec generic is not booting stuck at network driver loading..
Is it possible to add below features..
- disable inbuilt keyboard? (not working - random keys get inputted)
- display bios over hdmi output?
- power on - when ac power on
- power on - wake on lan
Thanks once again
After PFSense discontinued support for 32bit your bios became golden for me. Many thanks to you. You saved me $$$.
