The system software that controls the equipment is installed on HDD.
There are two types of system software; system software 1 for CPU1 (IC51), system software 2 for CPU2 (IC45).
When the host machine is started, the CPU1 loads the BIOS program in BIOS to the SDRAM for system processing, and then loads the system software 1 and the
system software 2 from HDD to the SDRAM for system processing. After that, the CPU 1 executes the system software 1.
The CPU2 requests the system software 2 to the CPU1 according to the BOOT program in the BOOTROM.
The system software 2 is transferred from the SDRAM for system processing to the SDRAM for image processing, and then executed.

While the CPU1 or the CPU2 is reading system software from HDD to SDRAM and executing start-up sequence including hardware initialization, the following
screen is displayed, where the progress bar indicates the progress status.

MEMO:
The boot program (included in system program 1) of the CPU1 (IC51) is stored in HDD.
HDD is accessed while the progress bar is being displayed. Never turn off the main power.
If the main power is turned off, a fault in HDD (E602) may occur.
