I am having some problems with my floppy disk controller driver:
- Resetting the controller using either DSR or DOR will trigger IRQ 6 on Qemu, but not on real hardware.
- Sending the Calibrate command to the controller won't trigger IRQ 6.
My code is available here: https://github.com/weedboi6969/puckos. Can someone help me with fixing the problems?

I have no experience with floppies, and I know this doesn't answer your question, but why would you want to support floppies at all, whether it is emulated or real HW? ATA hard disks are even simpler than floppies, and most real hardware with SATA controllers can be configured in the BIOS to work in emulated IDE mode, so why not just use hard disks?

My kernel can be booted from floppy, CD or HDD, and I want to support all of them.

Are you using an usb floppy on real hw? Then it wont work
