First operation

101 on using the CD-berry

From this on the Raspberry Pi Zero will be called CD-berry

Start to use

1. Connect the CD-berry to your computer
2. When is has booted, the status led will start blinking with short pulses
3. A new USB drive will appear (labeled CD-berry). It should contain a mount report. If that contains errors, may be the ntfs partition has to be reformatted. Read the manual
4. Copy an .iso file to root of this drive
5. Rename it to cdrom.iso (lower case)
6. Now eject the USB mass storage drive. In Windows, right click the drive and choose 'Eject'
7. After a little while, the status led will start blinking with long pulses
8. The CD-ROM should now appear
9. Ejecting the CD-ROM will revert the CD-berry to USB mass storage mode

Shutting it down

Because it is an OS after all it should be shut downed properly

1. Press the button for about 3 seconds. At first the status led blinks half a second on, half a second off. Keep the button pressed until it starts blinking fast
2. If the CD-berry is currently in CD-ROM mode, it will shutdown immediately. Just wait for the power led to turn off
3. If the CD-berry is in USB mass storage mode, Eject the drive, within 12 seconds. The CD-berry will shutdown. Watch the power led

Booting from cd CD-berry

When the CD-berry is powered up and a cdrom.iso exists, it will start in CD-ROM emulation mode. This makes is possible to boot from the device, depending whether a bootable .iso was copied to the CD-berry.

Sometimes the computer is too fast to discover the CD-berry CD-ROM at boot time, because the CD-berry is still booting. In that case, reboot the computer a few times in succession, or pause the boot sequence if possible. Most computers will leave the USB ports powered, so after some the CD-berry has started and then can be discovered.
