I'm trying to set up my first hackintosh ever, but the system I'm using for it is quite old. I have a modded xeon E5420 on an ASRock G41C-S, with 2x4 GB of DDR3 memory and a GT510 as graphics card. I followed a video tutorial on youtube (https://youtu.be/O8fCgmQd7SY) but at 9:48 the guy in the video says that the bootflags he's using are only for his specific machine (in fact those don't work for me). How can I know my bootflags? I haven't completely understood what a bootflag is right now, since this is my first experience with hackintosh. If anyone can help me, thanks.
