In "normal" bochs i was able to setup breakpoints, for example:
Normal bochs session wrote:
1. Restore factory default configuration
2. Read options from...
3. Edit options
4. Save options to...
5. Begin simulation
6. Quit now
Please choose one: [5]
Next at t=0
(0) [0x000ffff0] f000:fff0 (unk. ctxt): jmp f000:e05b ; ea5be000f0
<bochs:1> b 0x7c00
And now I have a problem in repeating this using gdb-stub, bochs was compiled with
configure option wrote:
./configure --enable-gdb-stub
, starting session results in
