评论代码:

结构长靴用来进入布拉格反射,读写磁盘的参数.display_info()功能,显示器的各种参数盘,读来自布拉格反射.recover_with_values()功能是用来改变参数布拉格反射回软的.

用价值功能recover_with_values()、参数为1.44mb,3½英寸软盘的布拉格反射. 描写这些价值观已经在桌上给下一:

Value价值

Jump Code of 3 Bytes For specified Floppy, has been given EB 3E 90 (H)典试跳3字节软,已束第3E90(八)

strcpy(b.system_id," +05PSIHC ");strcpy(b.system_id"05psihc");

System Id of 8 Bytes.系统编号800字节. It is calculated with current date and time of the system, however almost anything works.据计算,目前该系统的日期和时间,但是几乎什么作品.
