+# ASUS P8Z77-M Pro
+
+This page describes how to run coreboot on the [ASUS P8Z77-M Pro]
+
+## Flashing coreboot
+
+```eval_rst

+
+The flash IC is located right next to one of the SATA ports:
+![](p8z77-m_pro.jpg)
+
+### Internal programming
+
+The main SPI flash cannot be written because Asus disables BIOSWE and
+enables BLE/SMM_BWP flags in BIOS_CNTL for their latest bioses.
+An external programmer is required. You must flash standalone,
+flashing in-circuit doesn't work. The flash chip is socketed, so it's
+easy to remove and reflash.
+
+## Working
+
+- PS/2 keyboard with SeaBIOS & Tianocore (in Mint 18.3/19.1)
+
+- Rear/front headphones connector audio & mic
+
+- S3 Suspend to RAM (tested with OS installed in a HDD/SSD and also with a
+  Mint 18.3/19.1 LiveUSB pendrive connected to USB3/USB2), but please
+  see [Known issues]
+
+- USB2 on rear (tested mouse/keyboard plugged there. Also, booting with
+  a Mint 18./19.1 LiveUSB works ok)
+
+- USB3 (Z77's and Asmedia's works, but please see [Known issues])
+
+- Gigabit Ethernet (RTL8111F)
+
+- SATA3, SATA2 and eSATA (tested on all ports, hot-swap and TCG OPAL working)
+    (Blue SATA2)  (Blue SATA2)  (White SATA3)  (Red eSATA SATA3 rear)
+       port 3        port 5         port 1             port 8
+       port 4        port 6         port 2             port 7
+
+- NVME SSD boot on PCIe-x16/x8/4x slot using Tianocore
+  (tested with M.2-to-PCIe adapter and a M.2 Samsung EVO 970 SSD)
+
+- CPU Temp sensors (tested PSensor on linux + HWINFO64 on Win10)
+
+- TPM on TPM-header (tested tpm-tools with Asus TPM 1.2 Infineon SLB9635TT12)
+
+- Native raminit and also MRC.bin(systemagent-r6.bin) memory initialization
+  (please see [Native raminit compatibility] and [MRC memory compatibility])
+
+- Integrated graphics with both libgfxinit and the Intel Video BIOS OpROM
+  (VGA/DVI-D/HDMI tested and working)
+
+- 1x PCIe GPU in PCIe-16x/8x/4x slots (tested using Zotac GeForce GTX
+  750Ti and FirePro W5100 under Mint 18.3/19.1)
+
+## Known issues
+
+- The rear's USB3s on bottom (closest to the PCB) have problems booting or
+  being used before the OS loads. For better compatibility, please use
+  the Z77's ones above the Ethernet connector or the Asmedia's top one
+
+- After S3 suspend, some USB3 connectors on rear seem not to work
+
+- At the moment, the power led does not blink when entering S3 state
+
+- Currently, we have not setup the SuperIO's Hardware Monitor (HWM),
+  so only the CPU sensors are reported
+
+- If you use the MRC.bin, the NVRAM variable gfx_uma_size may be ignored
+  as IGP's UMA could be reconfigured by the blob
+
+- Using TianoCore + a PCIe GPU under Windows crashes with an
+  ACPI_BIOS_ERROR fatal code, not sure why. Using just the IGP
+  works perfectly
+
+- Under Windows 10, if you experiment problems with PS/2 devices, change
+  HKLM\SYSTEM\CurrentControlSet\Services\i8042prt->Start from '3' to '1'
+
+## Untested
+
+- EHCI debugging
+- S/PDIF audio
+- Wake-on-LAN
+- Serial port
+
+## Not working
+
+- PS/2 keyboard in Win10 using Tianocore (please see [Known issues])
+- PS/2 mouse using Tianocore
+- PCIe graphics card on Windows and Tianocore (throws critical ACPI_BIOS_ERROR)
+
+## Native raminit compatibility
+
+- GSkill F3-2133C10D-16GAB(XMP,1.60v) 2x8GB kit works at 1333Mhz instead
+  of XMP 2133Mhz
+
+- Team Xtreem TXD38G2133HC9NDC01(XMP,1.50v) 2x4GB kit works at 1600Mhz
+  instead of XMP 2133Mhz
+
+- Kingston KVR1066D3N7K2/4G(JEDEC,1.50v) 2x4GB kit works at 1066Mhz
+  but the board only detects half its RAM, because those DIMMs have
+  Double Sided(DS) chips and seems only Single Sided(SS) ones are
+  fully detected
+
+- GSkill F3-10666CL9T2-24GBRL(JEDEC,1.50v) 6x4GB kit (4 DIMMs used)
+  works perfectly at full speed (1333Mhz)
+
+## MRC memory compatibility
