 ## Flashing
 
-### SD Card
+### Linux
+
 ```bash
+# SD Card:
 sudo dd if=build/out/rpi-audio-mixer-*.img of=/dev/mmcblk0 bs=4M status=progress conv=fsync
-```
 
-### USB SSD
-```bash
+# USB SSD:
 sudo dd if=build/out/rpi-audio-mixer-*.img of=/dev/sda bs=4M status=progress conv=fsync
-# Then on Pi: sudo rpi-eeprom-config --edit → BOOT_ORDER=0xf41
+
+# NVMe HAT:
+sudo dd if=build/out/rpi-audio-mixer-*.img of=/dev/nvme0n1 bs=4M status=progress conv=fsync
 ```
 
-### NVMe HAT
+### macOS
+
 ```bash
-sudo dd if=build/out/rpi-audio-mixer-*.img of=/dev/nvme0n1 bs=4M status=progress conv=fsync
-# Then on Pi: sudo rpi-eeprom-config --edit → BOOT_ORDER=0xf614

+diskutil unmountDisk /dev/diskX
+sudo dd if=build/out/rpi-audio-mixer-*.img of=/dev/rdiskX bs=4m status=progress
+diskutil eject /dev/diskX
 ```
 
+### Windows
+
+Use [Raspberry Pi Imager](https://www.raspberrypi.com/software/) or [balenaEtcher](https://www.balena.io/etcher/).
+
+## Configuring EEPROM Boot Order
+
+The RPi4B boots from SD card by default. To boot from USB or NVMe, configure the EEPROM once:
+
+```bash
+# Check current
+sudo rpi-eeprom-config
+
+# Edit
+sudo rpi-eeprom-config --edit
+```
+
+| Boot Order | Sequence |
+|---|---|
+| `BOOT_ORDER=0xf41` | USB → SD → Restart |
+| `BOOT_ORDER=0xf614` | NVMe → USB → SD → Restart |
+
+### First-Boot Bootstrap
+
+Without a working SD card, flash RPiOS Lite to a temporary SD, boot, configure EEPROM, then switch to your USB/NVMe drive.
+
+### Boot Device Codes
+
+- `0x0` = SD Card (SDIO)
+- `0x1` = USB Mass Storage
+- `0x2` = NVMe (PCIe)
+- `0x6` = Network (PXE)
+- `0xf` = Stop/Restart
