Don’t Throw Away That Old Pentium 4!

How to turn a 15-year-old computer into a powerful Automated School Bell System.

Do you have an old computer gathering dust in your school lab? Maybe it’s a Pentium 4 with only 1GB of RAM that struggles to run Windows 7. Before you send it to the scrap heap, I have good news: That computer is perfect for running the School ICT Automated Bell System.

The problem isn’t the computer; it’s the operating system. Windows 7 uses about 800MB of RAM just to stay awake, leaving no room for your applications. By switching to a lightweight Linux distribution, we can free up that memory and run the Bell System smoothly 24/7.

In this guide, I will show you exactly how to install Q4OS Linux, fix common sound issues, and set up the automated bell system on hardware from 2005.

Step 1: Download the Right Linux Version

Since most old school computers are 32-bit (x86), you cannot use standard modern operating systems. We need a specific “Distro” designed for older hardware.

My Recommendation: Q4OS (Trinity Desktop) Q4OS is excellent because it looks almost exactly like Windows XP/7, so other teachers won’t feel lost using it.

1. Go to the Q4OS Downloads Page.
2. Look for “Q4OS Aquarius, Trinity, install-cd – 32bit / i386”.
3. Click Download (The file is about 600MB-800MB).
   • Note: Do not download the “64bit / x64” version unless you are sure your PC supports it.

Step 2: Create a Bootable USB (The Right Way)

Old computers are picky. If you don’t burn the USB correctly, it won’t boot.

1. Download Rufus on a working Windows PC.
2. Insert your USB drive (4GB or larger).
3. Crucial Settings:
   • Device: Select your USB.
   • Boot Selection: Select the Q4OS ISO file you downloaded.
   • Partition Scheme: Change this to MBR (Not GPT).
   • Target System: “BIOS (or UEFI-CSM)”.
4. Click START.

Tip: If the old computer refuses to boot from USB, use software like ImgBurn to burn the ISO file to a blank DVD. Optical drives are often more reliable on Pentium 4 machines.

Step 3: Installation

1. Plug the USB/DVD into the old PC.
2. Turn it on and tap the Boot Menu Key (usually F12, F9, or Del) immediately.
3. Select your USB device from the list.
4. Follow the on-screen instructions. Select “Erase Disk and Install Q4OS” to give the system maximum speed.

Step 4: The “No Sound” Fix (IMPORTANT)

After installing Linux on old hardware, you might find the sound doesn’t work. This is the most common issue, but it is easy to fix.

Fix A: Configure the Driver (TDE Control)

1. Go to Start Menu > Control Panel > Sound & Multimedia.
2. Open Sound System (or “TDE Control Module”).
3. Go to the Hardware tab.
4. Under “Select the audio device”, change it from “Open Sound System” (which is obsolete) to “Advanced Linux Sound Architecture” (ALSA).
5. Click Apply.

Fix B: Unmute the Hardware Switch Linux often installs with the sound card “Muted” for safety.

1. Open the Terminal (Black screen icon).
2. Type alsamixer and press Enter.
3. Look at the “Master” bar.
   • If you see MM at the bottom, it is Muted.
   • Press M on your keyboard to switch it to 00 (On).
4. Use the Up Arrow key to raise the volume to the green zone.
5. Press Esc to exit.

Fix C: Test It In the terminal, type: speaker-test -t wav -c 2 If you hear a voice saying “Front Left… Front Right”, your audio is fixed!

Step 5: Setting Up the Bell System

Now that your robust Linux machine is ready, let’s run the School Bell System.

1. Download the System: Get the latest Bell System files (HTML + JS + MP3s) from SchoolICT.net.
2. Copy to Desktop: Move the folder to your Linux desktop.
3. Browser Settings (Crucial): Modern browsers block “Auto-play” audio by default. We must allow it so the bells ring automatically.
   • Firefox: Go to Settings > Privacy & Security > Permissions > Autoplay. Change “Default for all websites” to “Allow Audio and Video”.
   • Chromium: Click the Lock icon near the address bar > Site Settings > Sound > Allow.
4. Run It: Open the .html file in the browser. Leave it running, and your bells will ring automatically on schedule!

Summary

By spending 30 minutes installing Linux, you have saved your school the cost of a new computer. This setup is virus-free, stable, and perfect for the 24/7 nature of a bell system.
