ACER 1360 BIOS 1.15 Model ID check error

I’m recovering a heat-damaged Acer Aspire 1360 and I wanted to update the BIOS. I went to the Acer web site and found the 1.15 version. This didn’t install but failed with a “Model ID check error”.

I re-downloaded the file from a different Acer site (UK and US) but same problem. I then tried the Acer FTP site,

and sure enough I found the problem.

The old BIOS files had two models in them, the 1520 and the 1360 but the version 1.15 only has the Acer Aspire 1520 files.

So AFAIKS you can only flash to version 1.11 of the BIOS (this gives 64 bit support).
