Thank to the God and BIOS coders

FreeDOS assigns the volume letter to a physical drive it gets from the BIOS

There is none. None of the legacy DOS kernels provides a proper volume management.

Note: Bret's USBDOS driver set tries to provide this by [ab]using the "block device driver" hack. But then, forget BIOS support.

BTW, the proper way of doing is an USB driver, not BIOS. BIOS most likely will assign physical disks to storage devices (how many???) found just before booting, no idea what happens if you change the device or add one.

Yeah

This means???

Good

AFAIK the BIOS fakes a PS/2 mouse (using the hacky SMM CPU mode?). CUTEMOUSE definitely doesn't know anything about USB.

Right
