Type the'help' command behind the command prompt to list the basic commands for debugging the system.
#RUN BOCHS IN DEBUG SERIAL#
Among them is the command input prompt, and the number in it represents the current command serial number. 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. (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.

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. 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. This is also one of the main reasons why this article chooses Bochs as the preferred experimental environment. I found some good information, and I want to put it on my blog, so that I don’t find it when I want to use it later
#RUN BOCHS IN DEBUG CODE#
Recently, I am studying the kernel code of linux0.11, mainly referring to the book "Linux Kernel Complete Notes" by
