Hello,
 
Just a heads up, i was lead to believe that 1.26 was a bios that supported the resize bar feature. Installed new resize bar feature via evga's px1 and this lead to motherboard stuck on post code "d4". After multiple reboots/cold boot, didn't work, didn't try clear cmos though. Flipped my 3080ftw3u hydrocopper from "normal" bios to "oc" bios, it booted. Updated motherboard to 1.28 and reverted gpu from "oc" to "normal" and it worked. This is just a heads up. With 1.26 i was lead to believe i was okay (even though px1 was telling me to update) since in the changelog it says it "supports" resize bar but for me, it didn't.
 
No need to comment or anything it's just in case someone comes across the same problem. Easy fix if you have double vga bios. Otherwise -_-
 
Cheers!
