Giovo17,
My experience with the i5-3470's HD2500 graphics is that you have to
double check your BIOS settings. Boot and F10 gives you access to the
settings. You first have to go to Advanced, Device Settings and enable
integrated video. F10 to accept and reboot and F10 again. Then go to
Advanced, VGA Configuration. My experience has been that it is better
to set the HD2500 graphics as secondary, and boot off the discrete graphics
as primary. I think trying to set the HD2500 graphics as primary may
create a perpetual boot loop.
You should also check your settings in BIOS under Advanced, Option Rom
Launch Policy. Some graphics cards want Legacy and some want UEFI.
I'm still confused about your profile, however. I'm under the impression
that the GT640 is not metal compatible, and won't work with Catalina.
Similarly, the HD2500 graphics isn't very capable beyond the headless
configuration with ig-platform-id set to 06006201 (as Shiki recommends)
or 07005201 (the default if unconfigured), and cannot serve as the primary
graphics either.
What discrete graphics are you using?

GT640 is Kepler (GK-107) based graphics card
It is metal compatible, and work with Catalina out of the box.
