NEWAX now adds support for planar modes, usable also for older GeForce. Maybe after many year of broken VBE nV finally get correct VBIOS that it deserves :)

NEWAX was originally designed for Kepler/Maxwell/Pascal cards, where VESA function 4F07h (Set/Get Display Start Address) is broken and requires the CRTC register workaround. However, version 0.8 now includes several additional fixes — most notably the 4F05h VRAM bounds check, the 4F01h page count recalculation, and the PLANAR mode support — which are potentially useful on older Nvidia cards as well (GeForce 6/7/8/9 series and GT2xx), where 4F07h is functional but other VESA issues may still be present.


It also some way helps on newer nvidia cards, like: RTX A4000 (Ampere, neither 4F06h nor 4F07h works there).
