GTX970 with Pegatron 2AB5 (not working)

[gpbob 2]

Looking for inputs and recommended solutions regarding my motherboard and the ability to accept a newer GPU.  Because I currently have the GTX660
running ok I expected to be able to update to a GTX970 without problems.  When installed, the computer will not boot beyond the HP boot screen.  A
little research on forums seems to indicate that the Pegatron MOBO has this bios version that isn't supported any longer and requires a version 8 bios
which doesn't exist in order to run the GTX970.  Short of installing a new MOBO is there another solution?

How about a Radeon GPU?  Is there any difference between Nvidia and AMD regarding the ability to be backwards compatable to this AMI bios? Seems the

R9 390 should also work on a 600W PSU but not sure its compatable with the bios??

Thanks to the community for some advice!

 

System Specs: Hewlett Packard h8-1070t, I7 2600 3.4Ghz, GTX660, Mobo - Pegatron 2AB5 with AMI bios version 7.05, 600W PSU

OK, I'll reply to myself - tried a Radeon card with same result.  Looks like a new MOBO is in the cards.  I'm hoping to get myself back to the GTX970 based on the excellent reviews I see on AVSIM

I have a motherboard Pegatron 2AB5 (also called "IPISB-CH2") and i had the same problem with my new Video Card GT610

my problem was solved when i used a modified BIOS found on this link:
