Hi! Below the post related to version 'P01.B1'. It seems that only ACER has it and did not published it. Charon13 said 'Service BIOS' sent only from ACER. My desktop has a serial starting with this reference DT.VDJEM.127…

Danke! Charon13 was ist der Unterschied zwischen dieser Service Bios und "normalen" bios? mejo sagte bereits erhalten und blitzte...

können Sie mir bitte senden BIOS version 'P01-B1'.

Besides the size is really different: P01-B0.2M --> 2048 Kb P02-A1.2M --> 2560 Kb

I wanted to flash the latest BIOS version "P02.A1L" but I got this error message:" Rom fle size does not match existing BIOS size". The same thing with…

Hi! Can you please send me this BIOS version. The official one is not working! Bitte können Sie mir diese schicken BIOS version.

I have re-downloaded the BIOS file but the same thing. I think that I should use the same BIOS version that I already have and check if the build date is new.

Ok! Thanks. I have this screen after trying to upgrade the bios: Reading file......... done FFS checksums..... ok –ROM file size does not match existing BIOS size

There is no issue. I want to have the most up to date Bios & Drivers. I have a Laptop (not Acer) and I made the bios upgrade easily by running the utility under windows. Thanks.
