HP Pavilion Wave Desktop 600--no icon menu at opencore boot - boots up fine after

howdy all, pulled this old project out for one last hurrah for hackintosh and was also tired of windows 10 install on the device being so lame and screwing around with edge vs chrome. Spruced up the opencore version to latest, redid my config, fixed a bunch of little problems and near the goal post

HP Pavilion Wave Desktop 600-a010 i5-6400T 2.20GHz 8GB

This was on one of those hard to hack ones that i cobbled together over time back in 2017, initially in clover, later a opencore conversion and currently everythings working finally over opencore 09.9, catalina. Bluetooth, usb, wifi [swapped card out when i bought it]. icloud. My only issue now is that im trying to update to Monterey and to facilitate that was trying to get the icon version of boot screen to work. Ive gone through the guides more than once and adjusted but still getting list, and this message below the boot list -
OOC: missingGOP on C.
crOut - unsupported PC: change resolution to 0x00

I believe this may have to do with intel graphics 530 not loading at first? not sure, any input for things to read up on or recheck would be appreciated
