====== Daniel Verkamp: COMBOOT Support ====== ===== Journal ===== ==== Week 8 ==== ---- === 15-17 July 2008 === * After a conversation with mcb30 last Thursday on how to fix the problems with COM32 stack overwrites during image loading, I've implemented his suggestions. This resulted in a 3-day debugging marathon until I switched to a simpler test case and just single stepped through the entire image execution process... and finally noticed (thanks to the Intel-syntax Bochs debugger) that I had written a constant as 12 instead of $12 (AT&T syntax strikes again :-)). But the upshot of all this is that COM32 programs using "Run kernel image" work totally correctly now, without any hack to limit the stack size, and I can say without reservation that menu.c32 is working perfectly fine now (given the configuration filename via the command line); it can load itself numerous times (until there is no more memory left to load the image again) as well as other image types without any problems now. I plan to start doing further testing on real hardware with various booting scenarios now, but so far, everything looks good.
