ATOM-15 Black screen
« on: February 06, 2017, 08:05:12 am »
Hi, having just flashed my third ATI card with ATOM-15 without the expected results I think it may be time to give up.

I tried a HD 4350, 6570 and recently a 6670 in an asus p8z77-v pro motherboard connected to a Sony PVM-20L.

All I get during boot up is a black screen until Windows and CRT-Emu drivers kick in. Atom-15 and ATI-winflash reported success with the flashing and my LCD went blank during the boot, yet displayed the BIOS before flashing so I believe the card is outputting the correct mode during boot, but either my MOBO, PVM or both are incompatible.

The PVM is 15.7 khz max so can't show 600i and the ASUS is UEFI. Is this a hopeless situation? I thought I'd at least see some text during boot up.

Thanks


EDIT* I tried the DVI-I port with a DVI/VGA adapter and still get a black scree and get nothing in windows until plugging back into VGA port

Hmmm, will a UEFI Bios display in 600i @50Hz? Your PVM is probably capable of 16.2kHz, so that might be a way around. I'm not sure where the Atom15 modelists are though. Just thinking out loud, really.

That sounds as if the mother board is disabling the card output for some reason, maybe due the safe boot feature. Is there an onboard GPU? Have you tried connecting the cable to it?

OK, just connected TV to onboard HDMI and the BIOS was displayed so I disabled iGPU and now the complete BIOS and bootup info is displayed on the CRT! I can't believe I didn't think of this, but very happy to have a fully contained MAME PC with no need for a second display.
