Remote debugging MBR bootloader on VMWare Workstation Pro with IDA Pro

Good afternoon everyone and nice to meet you all!

I'm a teacher and I'm developing a project to have my students better understand the invisible steps taken by an x86 32 bit computer before the OS boots up.

I'm able to enable the GDB debugging stub on my VMs and to connect to it from IDA Pro.

The problem is that I would like to see meaningful addresses, like "0xFFFF0h" for the reset vector or "0x7C00" for the first instruction of the MBR bootloader.

Instead of this, as soon as I attach Ida Pro to the GDB stub of VMWare Workstation, I get directed to address "0xFFFFFFFF" and I can then only press "Play" and I get lost in the code.

Can someone please help me?

My students would appreciate it too 😉
