Blinking underscore at boot, no response

Hello, I'm trying to set up my first Hackintosh on a Dell Latitude D630. So far I've used the vanilla install method (with gibMacOS, since I don't actually have a real Mac on hand) to create a bootable High Sierra install with OpenCore, followed all of the guides and popped in the necessary kexts/.efis/DDSTs/config.plist and I'm 89% sure I did all that correctly. I've got my SATA set to AHCI and all the BIOS settings, but when I try to boot all I get is a blinking underscore in the top left hand corner indefinitely. Is my CPU too old / does it need anything special to work? I'm running a Core 2 Duo T7500 with 4 GB of RAM and Intel x3100 graphics (built into the GMA 965 chipset). I've seen other posts on here of this old laptop working, but I'm still kind of inexperienced and would like some guidance.
