27 The flash IC is located right next to one of the SATA ports:
30 ### Internal programming
32 The main SPI flash cannot be written because Asus disables BIOSWE and
33 enables BLE/SMM_BWP flags in BIOS_CNTL for their latest bioses.
34 An external programmer is required. You must flash standalone,
35 flashing in-circuit doesn't work. The flash chip is socketed, so it's
36 easy to remove and reflash.
40 - PS/2 keyboard with SeaBIOS & edk2 (in Mint 18.3/19.1)
42 - Rear/front headphones connector audio & mic
44 - S3 Suspend to RAM (tested with OS installed in a HDD/SSD and also with a
45 Mint 18.3/19.1 LiveUSB pendrive connected to USB3/USB2), but please
48 - USB2 on rear (tested mouse/keyboard plugged there. Also, booting with
49 a Mint 18./19.1 LiveUSB works ok)
51 - USB3 (Z77's and Asmedia's works, but please see [Known issues])
53 - Gigabit Ethernet (RTL8111F)
55 - SATA3, SATA2 and eSATA (tested on all ports, hot-swap and TCG OPAL working)
56 (Blue SATA2) (Blue SATA2) (White SATA3) (Red eSATA SATA3 rear)
57 port 3 port 5 port 1 port 8
58 port 4 port 6 port 2 port 7
60 - NVME SSD boot on PCIe-x16/x8/4x slot using edk2
61 (tested with M.2-to-PCIe adapter and a M.2 Samsung EVO 970 SSD)
63 - CPU Temp sensors (tested PSensor on linux + HWINFO64 on Win10)
65 - TPM on TPM-header (tested tpm-tools with Asus TPM 1.2 Infineon SLB9635TT12)
67 - Native raminit and also MRC.bin(systemagent-r6.bin) memory initialization
68 (please see [Native raminit compatibility] and [MRC memory compatibility])
70 - Integrated graphics with both libgfxinit and the Intel Video BIOS OpROM
71 (VGA/DVI-D/HDMI tested and working)
73 - 1x PCIe GPU in PCIe-16x/8x/4x slots (tested using Zotac GeForce GTX
74 750Ti and FirePro W5100 under Mint 18.3/19.1)
78 - The rear's USB3s on bottom (closest to the PCB) have problems booting or
79 being used before the OS loads. For better compatibility, please use
80 the Z77's ones above the Ethernet connector or the Asmedia's top one
82 - After S3 suspend, some USB3 connectors on rear seem not to work
84 - At the moment, the power led does not blink when entering S3 state
86 - Currently, we have not setup the SuperIO's Hardware Monitor (HWM),
87 so only the CPU sensors are reported
89 - If you use the MRC.bin, the NVRAM variable gfx_uma_size may be ignored
90 as IGP's UMA could be reconfigured by the blob
92 - Using edk2 + a PCIe GPU under Windows crashes with an
93 ACPI_BIOS_ERROR fatal code, not sure why. Using just the IGP
96 - Under Windows 10, if you experiment problems with PS/2 devices, change
97 HKLM\SYSTEM\CurrentControlSet\Services\i8042prt->Start from '3' to '1'
108 - PS/2 keyboard in Win10 using edk2 (please see [Known issues])
109 - PS/2 mouse using edk2
110 - PCIe graphics card on Windows and edk2 (throws critical ACPI_BIOS_ERROR)
112 ## Native raminit compatibility
114 - GSkill F3-2133C10D-16GAB(XMP,1.60v) 2x8GB kit works at 1333Mhz instead
117 - Team Xtreem TXD38G2133HC9NDC01(XMP,1.50v) 2x4GB kit works at 1600Mhz
118 instead of XMP 2133Mhz
120 - Kingston KVR1066D3N7K2/4G(JEDEC,1.50v) 2x4GB kit works at 1066Mhz
121 but the board only detects half its RAM, because those DIMMs have
122 Double Sided(DS) chips and seems only Single Sided(SS) ones are
125 - GSkill F3-10666CL9T2-24GBRL(JEDEC,1.50v) 6x4GB kit (4 DIMMs used)
126 works perfectly at full speed (1333Mhz)
128 ## MRC memory compatibility
130 - GSkill F3-2133C10D-16GAB(XMP,1.60v) 2x8GB kit works at 1333Mhz
131 instead of XMP 2133Mhz
133 - Team Xtreem TXD38G2133HC9NDC01(XMP,1.50v) 2x4GB kit works at
134 1600Mhz instead of XMP 2133Mhz
136 - Kingston KVR1066D3N7K2/4G(JEDEC,1.50v) 2x4GB kit works at 1066Mhz
137 but the board only detects half its RAM, as those DIMMs have
138 Double Sided(DS) chips and seems only Single Sided(SS) ones are
141 - GSkill F3-10666CL9T2-24GBRL(JEDEC,1.50v) 6x4GB kit (4 DIMMs used)
142 works perfectly at full speed (1333Mhz)
