Hi, sadly not. Make sure not to change anything you don't know the effect of.
You should be able to find most settings with google.

If you have any specific question, I will try to answer.

Hello,
I've just flashed your modified bios rom. It works! Great job.

I have some questions.
Boot from SD card possible?
I had a issue before. My Lenovo S205 equipped with 2 GB of Hynix RAM. I've installed Kingston 2GB DDR3-1333 mhz. 4 GB of RAM was seen correctly but the issue was PC can't wake up from sleep mode, just black screen. I am gonna try it again with this bios, do I need to change some settings?

Hi cinowell,

thank you. I wouldn't expect too much. I only revealed the hidden page setting, nothing else. Neither did I see any settings related to the two issues you mentioned.
I never tried to boot with the internal card reader, only saw some posts about it. You might want to try to boot from it in UEFI mode, but that depends on what you want to achieve of course.

Hi Sml6396,

thanks for adding it, keep up the good work.

For those who want to change the wifi card (or already did), I attached the current BIOS for the S205 without wifi card whitelisting and with the hidden menu option from xsmile's first post.

Thanks to xsmile, you just did a wonderful job

Please adjust the settings the way xsmile posted above.
