Hi, Hoping someone can help me here.
I have a small issue with one of my rigs. this rig has 8x 580 8g Sapphire Nitro’s.
Recently my old Motherboard developed a fault and had to be replaced under warranty. They could not give me the same board, so instead I got a new MSI B460 Tomahawk as a replacement -no problem.
However, All my cards run modified vBios (of course) , and when the card that is plugged into the main PCI-E slot boots up on modified vbios - the motherboard gives me the ‘No GOP Support detected’ error. Then it automatically switches back to CSM mode.
I cannot run HIVE OS w/multiple cards in CSM mode. It must be UEFI mode.
So - the only way i can get the rig running , is to hit the vbios switch back to default on that one card and boot the system. Then that 1 card only manages around 27mh… so I’m loosing hash rate on 1 card.
It doesnt matter which bios i flash to… once I have flashed the bios in switch position 2, then It does not boot in UEFI (due to no GOP support).
How can I get GOP support working on my modified Vbios? OR … How can I disable the MSI Motherboard from checking for GOP on UEFI mode?
I understand there is some way of flashing GOP tables into the VBIOS , however the VBIOS is then too big for the flash…
SO - what have others done??? Surely I don’t have to put up with running one card on factory bios, just to pass the GOP Boot check??
