AFAIK, you can't: accessing page tables needs to run at ring 0, because the instructions to do that are privileged. > Also, can gdb display info about the LDT and GDT? What info about these tables do you want to display? > Can either of these debuggers dump memory using a specific selector? Please define ``dump memory''. GDB generally displays memory addresses as variables; if you mean ``dump memory'' the DEBUG.COM style, then it cannot do that, even for memory that is part of the normal DS selector addressable range. FSDB does have a memory pane, though. As for other selectors, I don't think you can do that currently. If you have specific needs, there might be a way to do something, so please consider telling what memory do you need to dump and why.
