Hi all, After Jerry's response I did a lookup of floppy drives in /dev directory and obtained a list of those beginning with fd0 (and identical list was there for fd1): fd0 fd0D360 fd0D720 fd0H1440 fd0H360 fd0H720 fd0d360 fd0h1200 fd0h360 fd0h720 Can I assume that when the system starts up it looks in ROM Bios and matches up my 1.44M floppy drive with its device driver fd0H1440 and uses its device info? What do all of the other numbers stand for and why are there repeats (360 appears four times)? If these numbers reference disk capacity does the letter preceeding it represent drive size (8", 5 1/4", 3 1/2")? Thanks.
