From d6fe56e5d70ef5a1f968d528734f71620a253a66 Mon Sep 17 00:00:00 2001 From: Konstantin Belousov Date: Tue, 11 Nov 2014 12:52:45 +0000 Subject: [PATCH] Based on some BIOS configuration (GGC register in host bridge, bit 1), IGP may declare subclass as either VGA-compatible, or non-VGA. The difference is that in the later case, IGP does not claim VGA cycles. Other than that, the device functions normally, and agp_i810 should attach to it.
