ULTRADSK Use this tool to save boot sector viruses from infected disks. It is very slow and meticulous but it won't miss any of the tricks viruses use to hide. It searches for hidden, odd numbered sectors, it searches for extra, hidden tracks, etc. If you send boot sector viruses to us, please use this tool to save them and zip the resulting file. To learn how to use it just type ULTRADSK and follow the instructions. RWIMAGE This tool is used to save and restore boot sector viruses. It is much faster than ULTRADSK and it will work 90% of the time. All of the boot sector viruses on this CD are stored as IMG files made with this program. One advantage of this program is that it will allow you to make an unusual format disk, e.g., you can make a standard 360K disk out of a 3-1/2" floppy. To use it, just type RWIMAGE and follow the instructions. PUTBS This program puts a boot sector stored in a file onto floppy disk. Just tell it the file to use and it will take the LAST 512 bytes of that file and write it to the specified floppy boot sector. Type PUTBS to learn how to use it. MOVEBS This moves the current boot sector to a selected Track, Head, and Sector on a floppy disk. It should be used in conjunction with PUTBS to reconstruct boot sector viruses from boot image files. Type MOVEBS to find out how to use it.
