Fixing PCI-Express for Coffee Lake CPUs on Sky/Kaby Lake non-Asrock(and some new Asrock) motherboards

LittleHill · March 1, 2018, 4:06pm

Hi,
how did you flash the BIOS? Gigabyte EEPROM is soldered, so no SPI flashing is easily possible.
Or did you use modified efiflash to get it flashed to the Board?

1st: it is SPI "serial" flash. Not EEPROM.
2nd: And you can usually contact the memory with adapter like this one : https://goo.gl/DFBA96

50/50change the SPI has grounded CS when board is off so if unlucky you actually have to desolder.

NOTE: This is only for the time when normal flashing of the bios fails.

Pretty sure Gigabyte is grounded or I fried the BIOS Chip on my last board. Couldn’t get it working in any way with flasher or rasppi GPIO.
Modified efiflash should be able to flash the modded BIOS in theory?

Gigabyte leave their Flash Description all 0xFF so you can use fptw64 -f to flash including ME or whatever you want to flash.

use efiflash.exe 0.44 version in Dos.

@all
anyone knows if 6-Core are already tested successfully on the z170 Boards?

use efiflash 0.44 version in dos.

Test with z270 gaming k3 is ok also.

asus strix z270-f have errors like this

Mov_AX_0xDEAD · March 1, 2018, 11:27pm

because this bios has new patterns, wait for next version

Hello, I would like to ask why the Clevo P7XXDM in the BIOS directly add microcode after the machine can boot, but will be stuck in the boot logo on it? You can enter the UEFI setting. But as long as any storage devices plugged in, the boot hard drive lights flashing several times on the card in the logo there.

dsanke · March 2, 2018, 2:47am

for additional
old bios only have 506e0 506e1 506e2 506e3 4 microcode updates and do not support kaby lake.
added 506e8 microcode trying to support kaby lake es cpu

IMaFish · March 2, 2018, 5:57am

Is it possible to achieve 7 or 8 generations of support by replacing modules in the P7xxDM BIOS with a DM2 BIOS module?Or replace the relevant modules in DM2BIOS to restore audio and power off?

Just patched and checked MSI Z170-A Pro, works fine with i3-8100, m.2 ssd, GTX 970.
Thanks!

the last version? 1203？

Mov_AX_0xDEAD · March 2, 2018, 9:50pm

yes, 1203. try use original bios (capsule) for test purpose

nickywin · March 2, 2018, 10:08pm

After test, the orginal bios is ok, but fixbios show these errors ( already fix the mc, gop and vbios)

is it importance?

or do the pcie patch first before mod the mc and gpu?

you have issues with dirs/rights/windows
ignore these errors, bios was patched OK
