+## Complete Silence: Disabling Firmware Beeps
+
+While our customized Arch Linux ISO disables system beeps at the operating system level, some computers may still emit beeps from the firmware/BIOS during the Power-On Self Test (POST) process. These beeps are controlled by your computer's firmware settings and cannot be disabled by the operating system.
+
+### Understanding Firmware vs. Operating System Beeps
+
+- **Firmware/BIOS Beeps**: Generated during boot before the operating system loads; indicate hardware status
+- **Operating System Beeps**: Generated by the OS after it has loaded; controlled by our customizations
+
+### Accessing UEFI/BIOS Settings
+
+To disable beeps at the firmware level, you'll need to access your computer's UEFI/BIOS settings:
+
+1. **Restart your computer**
+2. **Enter UEFI/BIOS setup** by pressing the appropriate key during boot:
+   - Common keys include: F1, F2, F10, F12, Del, or Esc
+   - The exact key varies by manufacturer (watch for on-screen prompts during boot)
+   - On newer systems with fast boot enabled, you may need to access BIOS through your OS's restart options
+
+### Common BIOS Beep Settings Locations
+
+Beep settings are typically found under different menus depending on your manufacturer:
+
+| Manufacturer | Common Menu Location                            | Setting Name                 |
+|-------------|------------------------------------------------|------------------------------|
+| Dell        | System Setup > POST Behavior                   | Keyboard Errors / Warnings   |
+| HP          | Advanced > Device Options                      | Beep Codes / POST Messages   |
+| Lenovo      | Config > Power > Beep and Alarm               | Power-On Beep / Keyboard Beep |
+| ASUS        | Advanced > Onboard Devices Configuration       | System Beep                  |
+| MSI         | Settings > Advanced > Integrated Peripherals   | Chassis Intrusion / USB Beep |
+| Gigabyte    | BIOS > Advanced > Boot                        | Quiet Boot / Boot Beep       |
+| Intel       | Advanced > Beep Options                        | Power-On Beep / Error Beep   |
+
+### UEFI vs. Legacy BIOS Navigation
+
+- **UEFI interfaces** typically have a graphical interface navigated with a mouse
+- **Legacy BIOS interfaces** usually require keyboard navigation with arrow keys and Enter/Esc
+
+### Common Beep-Related Settings
+
+Look for settings with these or similar names:
+
+- **System Beep** or **Power-On Beep**
+- **POST Beep**
+- **Audio Alert**
+- **Quiet Boot**
+- **Speaker** or **Internal Speaker**
+- **Boot Up Beep**
+- **Keyboard Beep** or **Keyboard Click**
+
+### Manufacturer-Specific Notes
+
+#### Dell Systems
+Dell computers often have the beep settings under "POST Behavior" in System Setup. Look for "Keyboard Errors" or "Warnings and Errors" options.
+
+#### HP Systems
+HP BIOS typically places beep controls under "Advanced" > "Device Options" or "Built-In Device Options", with settings like "Beep Codes" or "Startup Sound".
+
+#### Lenovo Systems
+Lenovo systems usually have beep settings under "Config" > "Power" or "Config" > "Beep and Alarm" with options like "Power-On Beep".
+
+#### ASUS Motherboards
+ASUS motherboards typically have a "System Beep" option under "Advanced" > "Onboard Devices Configuration".
+
+### After Disabling Firmware Beeps
+
+After disabling beeps in your BIOS/UEFI settings:
+
+1. **Save changes** and exit the BIOS/UEFI setup (usually F10 or a "Save & Exit" option)
+2. **Boot into Arch Linux** (your system should now be completely silent)
+3. Verify that both POST beeps and system beeps are disabled
+
+### When BIOS Beep Disabling Is Not Available
+
+Some systems don't provide options to disable firmware beeps. In these cases, you might consider:
+
+- Physically disconnecting the internal speaker (for desktop computers)
+- Using a headless configuration (no monitor) where supported
+- Checking for BIOS updates that might add beep control options
