Install - screen goes blank when pmshell starts

The System Evaluation (Alt-F1) at AOS boot from hard drive or Install/Maintain AOS menu says:
Display native resolution: 1920x1080 not in mode list. The mode list shows: 640x480, 800x600, 1024x768, 1280x1024.

The answer, if you insist on using the old video card, is to try the Panorama VESA driver and if it works use it. That is what I use on my Ryzen with built in graphics and it pushes 1920x1200 without problems.

Well, to have the System Evaluation thing means you are in EUFI mode. And the fact that SNAP is using the VBE driver shows something is not right with your X600, namely not compatible with UEFI makes it look like you have 2 choices, boot and install in legacy mode or use a different newer video board.
When booting from the thumb drive, have you tried using the F11 or F12 (depending on computer) built in boot manager? Perhaps try it and see if you get 2 choices of USB boot, might have to expand the USB drive to see both choices.
As for the PCIe 1X etc, on my computer I'm pretty sure it is speed related. There's been 4 or 5 generations of PCIe, each basically doubling the speed. An old card might work better at the lower speed.
Yours could be different.
Is there access to your MB's manual online?
Doug Clark:
Dave (and Ivan) - thank you for your help. I appreciate it.
I have attached the manual for the motherboard.
The message I saw about the video card was: "There is no GOP (Graphics Output Protocol) support detected in this graphics card. We recommend you use a GOP/UEFI compatible graphics card." I believe the system then turned on CSM itself.
I think I have two somewhat different issues: 1) the install program stops with a blank screen at PMSHELL, 2) whether SNAP and/or my Radeon X600 will run once the install is complete.
1) Install doesn't run
I THINK the issue with the AOS install is that AOS sets the resolution of the system to a mode that is not supported by the x600 when it switches to graphics mode during the install. I am basing this on the message from the system diagnostic, and that the x600 card doesn't support GOP. According to the web GOP replaces VESA as the method to communicate with graphics cards with UEFI.
If that is true, the potential fixes are: 1) buy a graphics card that supports GOP for the install, 2) get AN to add a option to the Boot with Own Values screens where you can specify a resolution for the rest of the install. The new graphics card will obviously be the fastest solution.
2) Whether the Radeon x600 and/or SNAP will run in UEFI.
Since development on SNAP stopped before UEFI was wide spread I doubt that SNAP used GOP to query the video card. And I seem to remember that the web said you couldn't use GOP to talk to the card once an OS was booted - although video type data built during the boot process could be accessed from the OS.
So the question is: can SNAP use VESA to talk to the video card installed on a machine using UEFI and CSM? I would think it would have to in order to run correctly - otherwise how would it know the video resolutions supported by the card and monitor.
And how does the AOS system diagnostics know what the supported video modes are without talking to the card?
I am not opposed to buying new video cards, if that is needed.
Once again - thanks
Dave Yeo:
Unluckily, UEFI, or at least the way it works with OS/2, custom resolutions do not work. Newer graphics card or figure out if a legacy boot is possible on your MB. I'll look at your manual.
BTW, add a testlog generic to your ticket.
