U盘第一扇区引导代吗，引导16~32扇区，U盘初始化为FAT32文件系统（注意笔记可能要求INT 13H 调用时DL=81H或者82H，本机为一体机测试用的是DL=0H）-U disk first sector of the boot-generation guide 16 to 32 sectors, U disk is initialized to the FAT32 file system (note the notes may require the invocation of the INT 13H DL = 81H or 82H, the machine is one machine for testing DL = 0H)
