Appendix B
PC3A Bootloader
The Bootloader is the program that runs when the PC3A is rst 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 PC3A 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 rst thing to understand is that PC3A executable programs and all object data reside on a le
system contained inside the instrument. This le system is based on ash memory technology
and will persist across power cycles. When the PC3A 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 PC3A also stores its factory-dened objects, and all of your own customized user objects on
the le system. The Bootloader program itself is not found on the le system. Instead, it resides in
a ROM chip that cannot be erased, and therefore is permanently installed in your PC3A.
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 PC3A Press this soft button to run the PC3A from the Boot Loader without
restarting the PC3A.
System Update Press this soft button to update the entire system (OS, objects, etc.) from a
.KUF le (Kurzweil update le.) You will be prompted to choose a USB
device and locate a .KUF le.
Run Diags Press this soft button to enter the PC3A diagnostics utility, which can help
determine if there’s a hardware error on your unit.
System Reset This will clear out all user-dened objects and return the PC3A to its
default “Factory” state.
System Utilities This oers a menu of le system functions that can be useful in
maintaining your system or diagnosing software problems.
