I tried running X-VESA Beta 5 on ZimaBoard (CPU: Intel Celeron N3350 [Apollo Lake], GPU: Intel HD Graphics 500) and the result was:
No VGA adapter detected

X‑VESA requires a real IBM‑compatible VGA core (sequencer, graphics controller, CRTC, planar modes, latch logic, etc.).

Intel Apollo Lake (HD Graphics 500) no longer includes a legacy VGA hardware block — only a VESA framebuffer interface provided by the firmware.

Because INT 10h function 1A00h does not return a valid VGA Display Combination Code (07h/08h), X‑VESA correctly reports “No VGA adapter detected”.

This is expected behavior on modern Intel SoCs where the VGA subsystem has been removed from the silicon.

That happened on my netbook with Intel N4020 CPU. There are various "fakevga" programs out there. The one I used to supplant this message, and get X-VESA and quickview pro, and others to run is called FAKEVGA.COM a small .com file which fools the system into thinking VGA is in the system by modifying INT 10 function.

Thank you for the information about FAKEVGA.COM.

Using FAKEVGA will indeed allow X-VESA to pass the initial VGA detection check, but this is strongly discouraged. X-VESA relies heavily on direct VGA hardware access throughout its execution — sequencer registers, CRTC, graphics controller, planar modes, latch logic — not just at startup. These are not optional code paths but core to almost every function X-VESA performs.

On systems without real VGA hardware, any of these accesses may produce unpredictable results or cause X-VESA to crash at any point during execution. This would not be a bug in X-VESA — it would be the expected consequence of running software that requires real VGA hardware on a system that does not have it.

In short: FAKEVGA + X-VESA on nonVGA/partialVGA or similar platforms = use at your own risk, crashes are expected and will not be investigated as bugs.
