all cbm IEC-bus devices (such as the 1541 discdrive) are so-called
"intelligent devices" ... they have their own cpu+ram+rom+i/o and so
they are basically a microcomputer of its own.... all the dos-stuff
you are referring to is entire handled by the drive itself, the c64
just issues commands like "open file xyz" or "read 2 bytes from open
file" or whatever.... the c64 doesnt (need to) know about the drives
hardware-layout by this time.
