Hi all, I'm having trouble doing a fresh install of CentOS 7.3. I'm using the DVD installer ISO, burned to a USB flash drive. The system is a Supermicro 7048 with four Nvidia Titan Xp GPUs, and I have the monitor connected to the first GPU. In the BIOS, VGA priority is set to Offboard, so I am seeing POST messages (good). The CentOS installer begins and shows a few messages on my monitor, but it stops after "Reached target Basic System" ok. At this point, if I connect a second monitor to the motherboard VGA port, then I see the installer continuing on that screen. Is there some way to install without using a VGA monitor? Thanks in advance.

You might be able to indicate which video device to use for default with the right video= parameter to the kernel for the bootloader. -- Jonathan Billings <billings at negate.org>

One reason in particular is that 7.5 has a fix for Meltdown and Spectre, which known to reduce performance. This machine will be airgapped, so performance trumps security.> I suggest going into the BIOS and disable the internal video port, if > that's possible.

The best I can do is switch VGA priority tooffboard, that controls which screen shows POST messages. Also ? this time it shows a few more lines, nouveau says unknown chipset (132000a1) So I think I can fix it by adding nomodeset to the boot options.
