Fortunately, it works just fine under wine albeit sometimes with noticeable--but not distracting--slowdowns. Here is the screenshot of Hexworkshop
Anyway, the difference between the AMI BIOS tools and Hexworkshop, lies in their installation method. You have to "install" Hexworkshop to wine (by using the winefile utility or other similar means) prior to using it, while AMI BIOS tools are just fine to invoke directly from the shell, such as:
pinczakko@opusera:~/work_in_progress$ wine AMIBCP_V3.37.exeThat's it. Now, I can mess with AMI BIOS file in Linux.
Since I have a rather weird 3G modem that doesn't work correctly in Windows, I have to use Linux (x86_64) to get online. This is a drawback when I want to do some BIOS modification, until just now. I experimented with Windows AMI BIOS tools recently in my Slamd64 Linux installation with wine. The result is promising. The BIOS binary produced by the AMI BIOS tools runs just fine, equal to modifying the BIOS in Windows. Well, there is some warning of unimplemented filename related API when I run MMTOOL but overall, it works just fine.
Below is AMIBCP screenshot running under wine in Linux

Perhaps, you noticed the weird font rendering. Well, I can't get the font right yet on applications running under wine in my system.
So, now I can do BIOS modification in Linux (at least AMIBIOS) without having to resort to the "painful" Windows installation in my machine.
