Subject: No OS Boot without a graphics card

Firstly sorry for my bad English, I speak badly this language

I mounted my new server for the house with these components:

- ASRock X470 Taichi Ultimate
- AMD Ryzen 5 2600
- Samsung SSD 970 EVO Plus M.2 PCIe NVMe
- G.Skill Fortis Series 32 Go (4x 8 Go) DDR4 2400 MHz CL15
- Controller card PCI-E 1 port RS-232 (DB-9)
- x8 Seagate barracuda 2TB

I use a graphics card the time of installation, everything works perfectly.
but when I remove the card (because on this server I do not want it for electrical consumption and I'm using ssh for this server) the server does not start.

I feel like it's stuck on the BIOS selection screen.
Is there an option in the bios to allow me to boot without a graphics card?

thank you in advance

The Ryzen 2600 has no integrated graphics, so you have to have a graphics card of some kind for it to run. I don't know of any option to allow boot with no graphics at all.

All my other servers under intel xeon with asrock card work without problem.
they do not have integrated display or graphics card

Why make this mandatory with amd?

It is an ASRock thing. Ryzens and TRs can run headless servers without any issue.

It's the mobo that actually checks for a GPU during POST and refuses to boot without one.

There is no solution? No adjustment possible in the bios?

There might be one. I am just not aware of it.

You can also try emailing tech support for more info.

Or you could get a $100 server/VM AMD GPU.

I have gpu, that's not the problem. Only for power consumption I do not want a gpu. ASRock allows it with Intel and not with AMD? weird

Most discrete GPU have a really low power draw in idle, while not feeding a monitor, e.g. 12-25W. Some have even lower power sip.

For 24/7 usage it really adds up, but what are your other options?

yes apparently I have no choice. I am disappointed with Asrock. Thanks for your help

I had to reboot just now so wandered through the BIOS, didn't see anything that sounded like allow headless boot except possibly for the boot splash screen option under Boot - I didn't experiment but you could try it.

I found a reddit posting where someone claimed to be able to boot headless with one of the Gigabyte B450 boards. The interesting bit is that Gigabyte told him no, that doesn't work, you have to have a GPU!

Late to the party, but: I've been able to boot without an attached monitor on an asrock b460m-itx/ac after enabling CSM in the BIOS. Otherwise, I got 5 beeps from the chassis speaker, and no boot.

I have some hosts on Asrock mainboards where i have inetl F without graphics and i can boot OS without any problems.

Asrock B460M Pro4 with i7-10700F   = OK
Asrock H370 Pro4 with i3-9100F     = OK
Asrock B460M-ITX/ac with i5-10400F = OK

Recently i purchased Gigabyte B460M DS3H with refused to boot with i5-10400F. I was thinking that it Gigabyte MB issue and last time i purchased again Asrock H470M-HVS and you know what? I can't boot OS without graphics. I have tried almost every option in BIOS and no luck.

BTW - i have checked OS logs and system try to BOOT, but something in the end goes wrong. Neworking is not starting, so i can't access it using ssh. We need a specialist to solve this.

/var/log/kern.log without graphics:

Apr 15 17:50:02 43oz-pve1 kernel: [    3.859298] softdog: initialized. soft_noboot=0 soft_margin=60 sec soft_panic=0 (nowayout=0)

Without grahics networking is not starting. Any ideas?
