Ok friend,
The best thing is to get the Tools to get free (SPI Programmer + Clip) but
We can try before this trick :
0x21067 Setting: LPSS SPI Support, Variable: 0x163
0x2108D Option: Disabled, Value: 0x0
0x210A9 Option: Enabled, Value: 0x1
0x210C5 End of Options
0x2179D Setting: BIOS Read/Write Protection, Variable: 0x1FC
0x217C3 Option: Enabled, Value: 0x1
0x217DF Option: Disabled, Value: 0x0 (default)
0x217FB End of Options
0x21A25 Setting: TXE HMRFPO , Variable: 0x170
0x21A4B Option: Disabled, Value: 0x0 (default)
0x21A67 Option: Enabled, Value: 0x1
0x21A83 End of Options
With the above, how would one amend these in a hex editor?
It's not to apply on Bios file but just to set into Hi-Mem Protected (NVRAM Emulation) so
only writing by FlaseClock Method is possible !
Regards
P.S. another user on Lenovo Yoga 2 Pro has done same and worked so i will ask to him !

Yoga Pro 2 has different bios though!!
I have tried GRUB and GRUB 2 and it boots to efi shell no problem.
It just will not boot that inside bios mod tool file, just hangs on black screen.

What is sleep bug?
Why would I need to downgrade the bios? I thought using SPI programme you extract from eeprom, modify and then flash modified bios?
I have searched for 92cn23ww / 92cn26ww, as these are the earlier bios versions for the yoga 2 11

I have ordered the tools.
I assume I will have to use the tools to provide a dump file for you?
Yes perfect !
Let me know just You get the tools to avoid to destroy Code into your Eeprom Chip as
We have to read before doing anything !

Hey
I have my CH341A programmer and SOIC8 cable.
Laptop has been stripped down and I have located the BIOS chip
What do I need to do now then / how do I use this thing? Assuming I plug programmer into another laptop, then hook up the cable to the programmer and then to the BIOS chip?
Thanks
Just read the FIrmware from the eeprom Chip and upload It here !
Let me know
Regards
