floppy

I'm trying to create a bootable floppy drive for my boot.bin and kernel.bin files. My boot.asm code is: bits 16 section .text start: JMP MAIN WAIT_FOR_KEY: MOV AH, 00H INT 16H RET CLEAR: MOV AH, 0H ;CHANGING THE VIDEO MODE TO CLEAR THE SCREEN MOV AL, 03H ;VIDEO MODE COD INT 10H RET LOG_TO_HTS: PUSH BX PUSH AX MOV BX, AX MOV DX, 0 DIV WORD[ALL_SECTORS] ADD DL, 01H MOV CL, DL MOV AX, BX MOV DX, 0 DIV WORD [ALL_SECTORS] MOV DX, 0 DIV WORD[FACES] MOV DH, DL MOV CH, AL POP AX POP BX MOV DL, BYTE [BOOT_DEVICE] RET ECHO: ;-=-=-=PRINTING FUNCTION =-=-=-; LODSB ;MOV ONE CHAR FROM SI TO AL AND DELETE IT

On Windows (XP-7), is there a reliable way of programatically differentiating between USB floppy drives and USB flash drives in C++? At the moment, I'm using WMI to get updates when new Win32_LogicalDisk instances are detected, and then using the DriveType attribute of the LogicalDisk object to figure out a basic type. This works quite well, except that floppy drives and USB flash drives are both of DriveType DRIVE_REMOVABLE , so to differentiate between those (floppy vs. flash), I'm using the IOCTL_STORAGE_GET_HOTPLUG_INFO interface to figure out if the device is hotpluggable, and was working

How do I write a .bin file to be in the first sector of a floppy disk/virtual floppy disk/floppy image? I'm trying to boot a simple 512-byte bootloader. The size on everywhere says "512 bytes" so I should be good already. Additional Information: The bootloader simply displays a string, and I'm learning simple assembly. Some of the work is made in Windows and some in Ubuntu 14.04 (Trusty Tahr) (if this matters). It doesn't boot even though it has the bootloader sign. If you are on Linux you can do it with DD utility. There is a version of DD for Microsoft Windows as well. General DD usage If
