+Subject: [PATCH 22/22] OvmfPkg/QemuVideoDxe: fix bochs mode init
+
+Add VgaInb() helper function to read vga registers.  With that in place
+fix the unblanking.  We need to put the ATT_ADDRESS_REGISTER flip flop
+into a known state, which is done by reading the
+INPUT_STATUS_1_REGISTER.  Reading the INPUT_STATUS_1_REGISTER only works
+when the device is in color mode, so make sure that bit (0x01) is set in
+MISC_OUTPUT_REGISTER.
+
+Currently the mode setting works more by luck because
+ATT_ADDRESS_REGISTER flip flop happens to be in the state we need.
