For the description of Bochs debugging function, please refer to the previous section 14.2, here is based on the Linux 0.11 kernel to explain the basic method of Bochs system debugging operation in the Windows environment.

"C:/Program Files/Bochs-2.1.1/bochsdbg" -q -f bochsrc-hd.bxrc chsdbg" -q -f bochsrc-hd.bxrc = Bochs x86 Emulator 2.1.1 Now create a simple batch file run.bat in the directory containing the kernel Image file, with the following content: We assume that the Bochs system has been installed in the directory "C:/Program Files/Bochs-2.1.1/", and the name of the Bochs configuration file of the Linux 0.11 system is bochsrc-hd.bxrc. Where bochsdbg It is the debug executive program of Bochs system. (0) context not implemented because BX_HAVE_HASH_MAP=0 Now the At this time, the main display window of Bochs is blank, and the control window will display something similar to the following:Ĭ:/Documents and Settings/john1/Desktop/Linux-0.11>"C:/Program Files/Bochs-2.1.1/boĠ0000000000i reading configuration from bochsrc-hd.bxrcĠ0000000000i installing win32 module as the Bochs GUIĠ0000000000i Warning: no rc file specified.Ġ0000000000i using log file bochsout.txt Run the batch command to enter the debugging environment. ctxt): jmp f000:e05b ea5be000f0Īt this point, the Bochs debugging system is ready to run, and the CPU execution pointer has pointed to the instruction at address 0x000fffff0 in the ROM BIOS.

This would be a tremendous speedup, but currently there are compiler errors about bit arithmetic. Either a nicer terminal output or SDL output in the browser

Currently it runs under node in the console.

I will try a clock divider since I don't need instruction-precise timers anyway. Not sure what to replace the instruction counter with since 32bit counter will overflow in (2^32instructions/30,000,000instructions/s/60s =) 2.5 minutes.

-s INLINING_LIMIT=0 compiles very slowly.

I am very concerned that doubles > 2^32 may not be monotonic when adding 1.

-s PRECISE_I64_MATH=0 will likely not work.

I have removed all files that were not absolutely necessary for compilation in order to get my bearings. This git repo is currently my work bench and a bastadization of the original bochs code.

It runs the BIOS code reasonably fast, but then goes down to 0.04MIPS instead of native 30MIPS.Īlso, I have almost no output options yet.

The code runs flawlessly under javascript. (Being) Ported by Johannes Ahlmann Status Inspired by Fabrice Bellard's fantastic jslinux.
