- DISCLAIMER - "I make no warranty with respect to this program, and
- disclaim any implied/explicit suggestions of usefulness for any
- purpose. Use this program only if you are willing to assume all risks,
- and damages,if any, arising as a result, even if it is caused by
- negligence or other fault."
-
- Functions:
-
- 1. Examine Boot Sector
-
- This simply reads the boot sector from drive A and presents all
- its parameters in an easy to read form.
-
- 2. Change Boot sector executability
-
- With the advent of the ST disk virus that has recently been
- discovered this function may prove useful. The known germ/virus
- spreads via an executable boot sector on a disk. This function
- tells you if a boot sector has the checksum of an executable one
- and allows you to toggle this status. Only the checksum on the
- sector is altered so if you changed it and you wish you hadn't
- then you can easily change it back again.
-
- Note: Not all disks with executable boot sectors contain a virus.
- Some games use this feature to boot up and DC Format uses it to
- set up various features at boot time. Giving a boot sector that
- doesn't contain code an executable checksum will just crash the
- system at boot.
-
- 3. Examine BIOS parameter block
-
- This function in combination with function 1 is useful to folk
- who like to know what the parameters on the disk are like.
- I used them a lot while writing the program.
-
- 4. Alter AUTO execution sequence
-
- Someone once had this on their wishlist of utilities and I never
- saw anyone bother to do it so here it is. This function displays
- the filenames of all the PRG's in the AUTO folder on the disk.
- You can then swap them in pairs to get them in the desired order.
- The program only reads in the first 32 PRGs it finds. This is no
- big deal since I have never seen much more than 3 programs in \AUTO.
-
- 5. Wipe FATs and Root Directory
-
- Oddly enough this is exactly what the ST virus does! So this could
- be regarded as a virus in a cage. (Friendly/tame virus anyone :-)
- Wiping the file allocation tables and the root directory is
- effectivly the same as dragging all the files and folders to the
- trashcan but much quicker.
-
- 6. Verify Floppy Disk
-
- After reading the boot sector to see how the disk is formatted
- this function then attempts to read every sector on the disk.
- As it does so it prints the side & track numbers on the screen.
- Any damaged tracks are printed in reverse video. You can abort
- the verify at any time by pressing escape. This can be handy
- if the disk is a real gonner.
-
- The Future:
-
- Currently the program only uses floppy drive A (or B if Verifying)
- and some people might want to use it on a hard disk. If there is
- enough demand I will probably add that.
-
- Expansions:sector editor, formatter, copier
