CMOS LockIt 2.3
Platform:
Turbo Assembler 4.0/Win16
Description:
A very strange project. Had you ever seen those BIOS crackers? They remove BIOS password if it's set. Well, this one does the inverse: it sets password into BIOS!!! "But why?", should you ask. My answer is: "I dunno". Use your creativity, damn! The largest exploitation should be... trojans. Argh!

P.S. - the second program, CMOSCONF, can be used as simple backup utility for CMOS data. Backup your CMOS data with it before you start playing!
P.P.S. - works on MS-DOS, Windows 3.11 & Windows 9x only!

demoniac beeper v0.666
Platform:
ANSI C (DOS/Win/Linux/FreeBSD)
Description:
Pretty funny. Plays Iron Maiden famous song Fear Of The Dark on PC Speaker. This is a very old project of mine. The original purpose is to provide sound alert on Linux machines with unavailable/weak sound card.
I used it to signalize when somebody telnets to my machine (my good old Sound Blaster AWE64 didn't allowed me to play any 16 and neither 8 bit sound when I was listening to some MP3).
Some days ago I needed such function but on Windows system so I decided to port demoniac to every system I'm able to program on :)
So currently it works on DOS, Windows 9x/NT/2K/XP, Linux & FreeBSD. Note that WinNT-derivated systems has native API to access PC Speaker hardware. Thus, administrator rights are only required on UN*X systems. (DOS & Win9x are single-user by default, duh).

P.S. - for more practical applications take also look at Eugeni Dodonov's libPCSpeaker which derivated from original beeper a long time ago :)

Keyboard Click
Platform:
Turbo Assembler 4.0/DOS
Description:
One of my first assembly programs. Produces click sound on the PC Speaker when any keyboard key is pressed. Authentic "Useless but Cool®" project! This is maybe the most simple TSR (Terminate Stay Resident) application. It can install & remove itself to/from low memory.

Parallel port LED controller v4.2
Platform:
Turbo Assembler 5.0/DOS
Description:
Simple control program for a homebuilt LED parport device. What the heck is that?! Look at the picture and schematic (note that resistors are 470 ohm). You can get more info at Tomi Engdahl page about Parallel port output. Now, back to program. it allows you to blink LEDs wired to your PC's parport and also performs some elementary operations on parport's data (NOT, ROL & ROR). Has a nice "GUI" with intuitive "keyboard shortcuts" ;)

XRio - X11 FrontEnd for Rio Utility
Platform:
Perl script
Description:


Discontinued Project!
I've developed Total Commander filesystem plugin with same funcionality. It's interface is much superior as it "steals" TC GUI; and it's native library instead of console front-end.
But... It's Windows only :(



X11 FrontEnd for Rio Utility v1.07 made by guys from Snowblind Alliance. Surely not the best nor most beautiful of all GUIs to manage Rio MP3 Player, but I tried to implement some ideas that "real" managers doesn't use. List of some "interesting" features:
  • 2 windows side-by-side like in Norton Commander legacy managers
  • specially optimized to manage big playlists and huge directories
  • displays remaining space as you select files to download
  • current file & overall progress bars
  • realtime display of transfer speed
Note that you need Perl Tk 800 library to get this soft running!

P.S. - if you get problems downloading files with long names, apply patch I provided above on Rio Utility (not XRio itself!)
