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

@M-HT

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.
