Noob Installation issues

[newpctech]

I have been searching with no luck, please flame me and point me in the correct direction is this is an old topic

I am doing an install (trying) and getting the error: uart8: <16558 or compatible> at port 8x3f8 irq 4 flags 8x18 on isa0
I am installing this on a generic pc with a 64bit Intel Atom Z8350 (Amazon ASIN = B0BJV88NRL) using the ISO OPNsense-22.7-OpenSSL-vga-amd64.img  - - the DVD iso will not pass the Rufus scan.

This is the first time I am trying this, every video I have seen shoots right past this line to the installation. The bios is not highly configurable

Help??

uart are serial ports. Likely you are using the serial version image and the installer not finding an enabled serial port (likely on generic modern machines). Double check it is definitively the vga image.
The lines before and after related to the error would be helpful too.

Thank you for your message – I decided to again download the files (VGA and DVD) and utilize Etcher to burn the thumb drive for installation.  The DVD ISO errors saying no boot files located, so burning ti anyway it is not discoverable from the bios boot menu. After burning the vga files, it is located in the boot menu and will boot only to stop in the same place.
The last several lines of the installation prior to stopping is:
atkbdc8: <Keyboard controller (18842)> at port 8x68, 0x64 on isa0
atkbd8: <AT Keyboard> irq 1 on atkbdc8
kbd8 at atkbd8 atkbd8: [GIANT-LOCKED]
uart8: <16558 or compatible> at port 8x3f8 irq 4 flags 8x18 on isa0

Im not sure what the next steps might be, I did however download pfsense and it stops in the same place – I am starting to assume it’s the platform, although the DVD/ISO still doesn’t burn from the files I downloaded on Rufus or Etcher

You need to resolve the issue with correctly burning the ISO. Did you confirm the checksum matches after downloading the image? If the checksums do not match, your download is bad.

Are you using a USB stick or an actual DVD drive?
As well as making sure the image is made correctly by trying booting with it on the machine used as an example, and verifying with the checksums, which is a little tricky if using windows, which I assume by the use of rufus, I am inclined to think the problem is with the BIOS settings. That is because of the messages where the installer seems to get stuck.
Verify the pc uses bios or uefi. If uefi, then if you can, use a USB stick and make sure the partition scheme of it is gpt so that the image can be loaded at boot time.
If the usb stick is formatted with mbr scheme, then the bios needs to be set to either legacy or hybrid uefi & legacy.
The OPN image needs to match. DVD and VGA support both. Serial only MBR.
I can't see the pc model with that reference to amazon, so I can't see what it is.
Actually, if it is this one https://www.amazon.com/Fanless-Processor-Computer-Dual-Band-Business/dp/B0BJV88NRL?th=1 you are aware that is only got one ethernet port, right?
