Looking for intel h57h-am2 DSDT patch

Trying to get ATI radeon HD 5450 working. Just did a fresh install and finally got the DSDT to open with MaciASL, but I still need to apply a patch right? I've got this guide to go off of, https://www.Tonymacx86/threads/guide-enabling-ati-radeon-hd-5450.180817/ but can't compile without any errors. That's about as far as I can get.

El capitan already installed Acer aspire m3910 u4012 radeon hd 5450 h57h-am2
