Good day sirs,

As one of OS Dev members pointed out I should use Bochs for my debugging, but as soon as I switched to it from QEMU, the system stopped booting and halts on floppy initialization.

Any ideas?

Yes, debug your code. Bochs never has bugs (well, they're rare enough that you must exhaust all other avenues and produce a minimum test case to be sure), so your code is at fault.

Printf spam, single stepping, cli;hlt, it's up to you.

Two things come to mind:

One: bochs is not designed (according to the wiki) to handle polling-mode FDC transfers, so if you don't use DMA this may be the problem.
Two: the floppy subsystem requires a timer and bochs BIOS leaves the PIT uninitialized.
