6 HIGH PERFORMANCE MODEL QCPU FILES
(2) Precautions
This section indicates the precautions for performing "Automatic write to standard
ROM"
(a) If the file to be booted from the memory card shares the same name as a
file in the program memory, the memory card data will be overwritten. Also,
if the file to be booted from the memory card does not share the same
name as a file in the program memory, it will be added to the program
memory. The "FILE SET ERROR (Error code: 2401)" will occur at this time
if the capacity of the program memory is exceeded.
(b) It is possible to select whether to perform the boot after the program
memory has been cleared, or perform the boot without clearing the program
memory when booting from the memory card to the program memory.
Performing the boot after the program memory has been cleared when
"Automatic write to standard ROM" prevents the program memory from
overflowing during the boot.
(c) The "Auto Download all Data from Memory card to Standard ROM" setting at
the "Boot file" tab screen is valid only when the High Performance model
QCPU parameter valid drive is to "Memory Card".
The "Auto Download all Data from Memory card to Standard ROM" setting
at the "Boot file” tab screen is disabled if the parameter valid drive is set to
"Program Memory" or "Standard ROM".
