MSI Z170A Bios Update Problems

I’ve got a Z170A Tomahawk mobo and downloaded latest bios from MSI.

On startup I hit Del to enter Bios, select M Flash. System reboots but the display shuts off and doesn’t come back on unless I switch off and on the PSU, which then stops me entering M Flash... repeat process several time but same thing keeps happening.

I’ve got dvi connected to onboard graphics. Cant see anything so cannot update bios.

I’ve tried connected to an R9 290X graphics card on pcie slot 2 through dvi on the card and that made no difference.

Any help would be greatly appreciated.

Update:

I did a hard reset of CMOS using a method previously recommended on this board:

1. turn off power, disconnect PSU.
2. Remove CMOS battery
3. Press + hold power button for 1min.
4. Bridge JBAT1 pins 1+2 for 10min
5. Remove bridge on JBAT1 pins
6. Reinstall CMOS Battery
7. Connect PSU and retry.

Worked like a charm... was able to complete BIOS update.
