Hello good day. I am going to install the F4-FMPAC board of the RBSC group and I would like to know what is the F4? I have heard that it is a MSX2 + registry, but I do not know what its function is or what it is for. Anyone know what is the F4 ?. Thank you

The F4 register is used for a.o. a soft reboot not showing the logo. So if a reboot of the system is initiated by the software running on the machine the boot logo is not displayed. More info on the I/O ports page by Grauw.
