I get VGA and boot lights. boot light is expected, as i dont have a HDD hooked up. i am using an i5-13600k processor, which has an igpu, but it wont USE that, and since i cannot see the bios (which it is booting into), it makes it impossible for me to do anything, like flash the bios, etc.

I was able to boot using an old ass GPU i had laying around....

But now I can't seem to figure out how to enable the iGpu function of my CPU, there doesnt seem to be a setting in the bios that addresses it. I updated to the latest bios (5.01 or whatever).

Onboard video just doesnt work.

I feel like the dumbest guy....

Turns out, when you search for "i5 13600k" on amazon, they will give you results for "i5 13600kf" as well as results for what you actually asked for.

long and short, the KF version doesnt have the iGPU. and that is what i bought. luckily, amazon returns are amazeballs. so i will have the right CPU tomorrow (only an $11 difference between the two, btw).
