Ok there is Always problem of disalignment beetwen two Eeproms :

--- Flash Devices Found ---
W25Q32BV ID:0xEF4016 Size: 4096KB (32768Kb)
EN25Q80A ID:0x1C3014 Size: 1024KB (8192Kb)

You have to edit the Fparts.txt file to get these two row with same comand 0x60 or 0xC7

W25Q32BV, 0xEF4016, 0x2000000, 0x1000, 0x20, 64, 0, 0xc7, 80000

EN25QH80, 0x1C7014, 0x800000, 0x1000, 0x20, 64, 0, 0x60, 80000

Use WinRar v.5.20 or above and open (not extract) the .exe file (last tool) and open the 8.1.10.1286
folder to edit the "fparts.txt" file then edit the rows to get same comand so both 0xC7 or 0x60 !
Or You can use the "fparts.txt" from the folder of Original FPT 8.1.10.1286 which You used to
make the Backup and replace into the .exe Tool NEW_BACKUP_FPTs.exe !
Let me know

As directed, I opened the last file you gave me and edited both so they were either 0x60 and 0xc7. I ran the tool for both combos. The results are below:

http://rghost.net/6CYTyrhtg


Recovery Procedure :

Prepare an USB Dos Formatted Fat32 Stick and copy file into

- Shutdown the netbook (notebook)
- Remove all peripheral devices
- Remove battery, Remove AC power cord
- Press and hold the power button for 10 seconds (battery and AC power still out), then release
- Put the USB Memory Stick in the USB port
- Hold "Fn" + "Esc" and plug the AC power cord in
- Now press the power button (whilst still holding Fn + Esc).
Wait until the fan will run, then release "Fn" + "Esc" keys
- The fan will run for about 2-10 minutes and the USB drive activity LED will blink
- I think the netbook rebooted automatically. If it doesn't, unplug the AC power cord once the fan has turned off

The bios should be updated with the modified BIOS, and boot as per normal.

Let me know

Success! I followed the above procedure, and the modded BIOS installed successfully. I am now on 2.09 with full SATA3 support (along with a bunch of other options to explore):



Thank you so much.

Edit: there's one other thing. Since this computer's primary operating system is MacOSX, would it be possible to add an option to this bios to unlock the MSR bit as described here:

Unfortunately this bios breaks bluetooth. I have a AW-CE123 BCM94352HMB wireless ac/bluetooth 4.0LTE combo card. In 2.21, bluetooth worked fine; in this bios, I lost bluetooth in both OSX and Windows10. I don't see any relevant options in the bios for bluetooth.

Well, I managed to brick the machine. I set the video ram to 384mb and the machine will no longer boot, nor can I access the recovery mode to flash back to the stock bios: while I can use fn+esc to get it into recovery mode (seemingly), it never reads the usb drive with the bios on it. I tried shorting the CMOS reset jumper, but still no luck. How a simple setting change in the BIOS can brick a machine so badly a CMOS clear won't fix it, I have no clue. Looks like I'm well and truly screwed.

Any help you could provide would be deeply appreciated.
