VESA modes in an NT driver?

Hello everyone,

my question is quite short:
Is it possible to use/set VESA display modes from within a standard NT
driver? I.e. can the driver call a BIOS interrupt such as 10h? If not, does
anyone have any information about VESA modes without use of the VESA BIOS
Extensions (VBE) - which require to call interrupt? If you don’t have
information, maybe you can point me to some book or website.

Thanks in advance,

Oliver

VideoPortInt10 is documented. So, if some of the modes you’re supporting
are VESA- compatible - then you can try implement mode switch using VESA.
