Hi all Looking around http://dev.haiku-os.org/ticket/3441 "ZeBeos not accessible" (and duplicates - 4408 5539 5696 5720) I added on-screen output to "haiku_loader" and then "stage1.S". It seems that the boot sequence does not enter the "haiku_loader" nor the "stage 1 boot code". Now, I'd like to add traces to the MBR boot code. The "kBootCode" array in \trunk\src\add-ons\kernel\partitioning_systems\intel\PartitionMapWriter.cpp contains the compiled code, but I can't find the source file. Is it in our repository ? Regards.
