Hello,
I flashed the bios of an ACER Z3770 PC with version P11-B0 BIOS P11-B0 and since then I have a problem detecting the hard drive:
The disk is well detected on the port but it no longer appears in the Hard Disk Drive Priority...

If I reset the bios by removing the battery, the PC boots without worries.

If I reboot the machine then I get a Disk Boot Error and the disk is undetected again.

I tried to flash the previous version P03-A2 P03-A2 but couldn't because I think the previous version flash is locked.

Do you have an idea or a solution to this problem?

I've been looking everywhere for 5 days and I can't find anything.
Thank you in advance :)

What do you mean?

I mean it's impossible to rollback by software solution.

That's what you say, but the program should return an error message. Let's leave the SPI flasher as a last resort.

Hello,

I try to write the original file from Acer directly in the chipset : the computer doesn't start anymore. I have the backup, it's ok but i really need to find someone who can make a fresh file with old bios version please.
Can you help me ?

Thank you very much.
