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.

Why? 7.5.1804 has been out since May of this year. You're going to end up downloading a ton of updates the first time.

I suggest going into the BIOS and disable the internal video port, if that's possible. You might be able to indicate which video device to use for default with the right video= parameter to the kernel for the bootloader.

For a specialized software, we have to wait for the developers to certify each new OS. They are still recommending 7.3. 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.

This is not possible. The best I can do is switch VGA priority to
offboard, 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.
