Is it possible to single-step through 16-bit real-mode code using the VirtualBox debugger?
In particular, I would like to be able to step through the boot process (i.e. from the execution of the guest's Master Boot Record). However, the 't' single-step command simply continues VM execution, as described previously in an April 4 2011 post for VBox 4.0.4 (original text below). Though I have encountered the same issue using the VBox 4.1.8. Previous message for reference: --- Elias Bachaalany lallousz-bochs at yahoo.com Mon Apr 4 11:54:10 CEST 2011 Hello, I am using VBox 4.0.4 with --dbg switch passed when I start the VM. Now in the debug console, I type: 1. stop The vm stops, I can inspect registers 2. t To single step However, I expect VBox to single step and break at the next instruction, instead is just resumes execution! --- Thanks in advance for any thoughts or advice. - Mike _______________________________________________ vbox-dev mailing list [email protected] https://www.virtualbox.org/mailman/listinfo/vbox-dev
