Appendix B
PC3K Bootloader
The Bootloader is the program that runs when the PC3K is first turned on. Its job is to check that
hardware is functional, initialize the digital systems, and load the main synthesizer program.
Under normal circumstances you might not even notice that the Bootloader is there at all, since
the PC3K will start up on its own without any problem. However, if you want to update your
unit, or perform maintenance on it, you may need to interact with the Bootloader program itself.
This appendix describes what the Bootloader can do and how you can use its functions.
The first thing to understand is that PC3K executable programs and all object data reside on a
file system contained inside the instrument. This file system is based on flash memory
technology and will persist across power cycles. When the PC3K starts up, the Bootloader copies
the synthesizer program into memory and executes it ‐ just like a PC “boots up” when you turn
it on. The PC3K also stores its factory ‐ defined objects, and all of your own customized user
objects on the file system. The Bootloader program itself is not found on the file system. Instead,
it resides in a ROM chip that cannot be erased, and therefore is permanently installed in your
PC3K.
Using the Bootloader Menu
Normally the Bootloader program will do its tasks and hand over control to the synthesizer
program automatically. If you want to interact with the Bootloader itself, hold down the Exit
button (to the right of the display) while turning the power on (while the message “Initializing
Scanner” is displayed on the front panel). Instead of completing the boot process, the Bootloader
will display its main menu page on the screen:
Use the soft buttons underneath the display to choose an action.
Run PC3K
Press this soft button to run the PC3K from the Boot Loader without
restarting the PC3K.
System Update
Press this soft button to update the entire system (OS, objects, etc.) from a
.KUF file (Kurzweil update file.) You will be prompted to choose a USB
device and locate a .KUF file.
Run Diags
Press this soft button to enter the PC3K diagnostics utility, which can help
determine if there’s a hardware error on your unit.
System Reset
This will clear out all user ‐ defined objects and return the PC3K to its
default “Factory” state.
