- HOT-BOOT 2
- John DeHaven (from original by Jason Loveman)
- (TSR - may be loaded high)
-
- A MINIMALIST TSR MANAGER AND BREAK-OUT UTILITY
-
- I am indebted to Jason Loveman for his wonderful tiny utility
- that has been part of my computing life for years. The way it
- came to me was sparse: the program, source, and a document.
- Jason did not indicate in any of these how he might be reached.
- Jason, wherever you are, thanks!
-
- NOTE: In the spirit of the original program this particular one
- is FREEware. In other words, if you ONLY use this program out
- of this collection, we will be happy if you don't send any
- shareware money. If you can find Jason, you might send HIM a
- little something...
-
- HISTORY
-
- The original hot-boot was conceived primarily as a "break-out"
- utility. If HOT is resident, then any time a program hangs, you
- can quickly break out with the keychord CTRL-ALT-INS. This is
- instant compared to a reboot attempt, and will often work when
- the CTRL-ALT-DEL reboot will not.
-
- OPERATION
-
- The idea is to run HOT at any time, and leave it lurking as a
- TSR. When, later, you hit CTRL-ALT-INS, the running program and
- HOT are dumped and your computer will be restored to the
- condition it was in before you ran HOT.
-
- Jason did not emphasize it, but I've used HOT as a minimalist
- TSR manager. It's possibly the smallest in existence. The idea
- is that that magic keychord not only dumps the running program
- and HOT itself, but all TSR programs that have been installed
- after HOT. Thoughtful application of HOT has paid off very well.
-
- The only caution about HOT that Jason mentions is that it should
- not be loaded after SideKick or other TSR programs that might
- fight with it for possession of that keychord.
-
- WHAT'S NEW?
-
- But now we are in a world of loading high and UMB's, and it was
- time to update this program to work as well in this new world.
-
- HOT2 works exactly like HOT did, except that it will also unload
- any programs that were loaded high into UMB memory after HOT2 was
- run and installed. HOT2 may itself be loaded high.
-
- HOT's dumping operation is very dangerous under Windows. HOT2
- will not attempt a dump if Windows is running.
-
- VIRUS IMPLICATIONS
-
- The original HOT would remove and deactivate many viruses. Just
- like removing any other TSR, it would remove TSR viruses that
- did not use "stealth" techniques or DOS memory management
- manipulations to defend themselves. This would work for viruses
- of this type (very common) that somehow got loaded after HOT was
- loaded.
-
- HOT2 will remove these, and also many that manipulate DOS memory
- management to conceal themselves, and some that might try to
- hide in the UMB memory. Stealth viruses of various flavors may
- evade HOT2. HOT2 is not intended to be a true anti-virus tool,
- but is useful in many cases, as a side-effect.
-
- LIMITS
-
- In order to keep HOT2 small, the number of "memory objects" it
- can record before it is loaded is limited to 50. This is more
- than sufficient for just about every computing environment. If
- by chance you have more memory objects than that, the behavior
- of HOT2 will revert to that of the original HOT program, which
- is still useful.
-
- Any technique like this will just about always work, but will
- never CERTAINLY work. Some programs may do exotic things to
- your system when they install and cannot be rolled back cleanly
- by HOT2 or the original HOT for that matter. An example of such
- a program is SMARTDRV. Still, HOT2 may bail you out of a sticky
- situation, and is always worth a try before you resort to the
- infamous red switch.
