Yes, you are correct, the listing no longer includes the comments. Sorry for causing you a problem. What is happening is that the preprocessor parser is stripping the comments during the creation of the .i file. Then, the compiler is invoked on the .i file -- thus, the comments are gone. This is going to take a bit of work to correct, but we will do it. In the meantime, try using the -Pn flag to disable the preprocessor. When this flag is set, the preprocessor is completely bypassed and the compiler should function as it did previously.

OK, I will take a look at it. Are all the comments throughout the code stripped from the listing? > -----Original Message----- > From: Idwer Vollering [mailto:vidwer@gmail.com] > Sent: Monday, July 30, 2012 10:35 AM > To: Moore, Robert > Cc: Michael S.

The last version of iASL that worked (for me) with SeaBIOS is acpica-unix-20120215. Idwer

It looks like the latest acpi compiler versions are stripping the comments out. You'll have to use an older version of the iasl compiler until we can update the SeaBIOS build. -Kevin
