Hi
I bought a DZ77GA-70K motherboard last month. General, my computer worked good with an integrated CPU i5-2500 video and without any overclocking.
My BIOS was the 0021 version. And I decided to upgrade it to the last BIOS (0066 version).
I made an upgrade by F7-way from USB-flash and I got the upgrade finish message 'successful'.
BUT, after restart my motherbord had bugs:
1*. I could not enter to the BIOS by F2 button, F7 and F10 buttons worked;
2*. the back-to-bios button and BIOS configuration jumper didn't work;
3*. the motherboard could not do an auto motheboard select to the integrated CPU i5-2500 video (black screen was on the hdmi output).
So, I decided do a BIOS rollback to another version. I inserted a PCI (not PCI-E) videocard in the motherboard and got a normal boot to my OS (without ability to enter BIOS!). I made BIOS update to 0063 version by 0063.EB.EXE-way from HDD. This BIOS version looks good: F2 button works, integrated CPU i5-2500 video works with auto motherboard select.
* - Tested with integrated CPU i5-2500 video and with external PCI (not PCI-E) videocard.
Is the BIOS version 0066 not good to use?
Is the BIOS version 0064 is stable and is it recommended to use?
Thank you in advance.
I'm sorry for my English.
