I have a new DQ87PG-Mainboard and tried to make it fit for Windows 8.1. On the Intel-Support-Site I found 6 Bios - Version 30, 35, 36, 121, 139 and 141.
My mainboard came with v. 30. I installed Win 8 and upgraded dirct to Win 8.1 - the PC worked well. Then I found Bios 139 with 8.1 support. I tried to flash Version 139 with all three methods - without succes, each with the same "FWUpdateFullBuffer" - error message. So I started to flash each version step by step. My results:
V 35 flash without error
V 36 flash without error
V 121 error - Bios file is not for DQ87PG, but for DB85FL Board
V 139 error FwUpdateFullBuffer
V 141 error FwUpdateFullBuffer
I'ts not my first experience with flashing mainboard, but I never hat such a number of problems.
The V 121 is more the a month on the support site, I found in an other discussion here a hint about this, but nothing happens.
I'm sure to maked a mistake by flashing the board! My system is plain vanilla:
DQ87PG Mainboard
I5-4670 Cpu
2*8 GB Kingston Memory
1 Samsung 849 EVO SSD-Drive
1 Plextor DVD-Drive
and it is quite good, stable an powerful.
