What modes ? All ???

Use safe resolutions 640x480 and 800x600.

> I think 640x480 is safe to run on most computers.
YES, there is VGA 640x480x4bpp with planes, B***-S*** VESA and LFB VESA.

COOL.

COOL :-)

Wrong. Who said this? Anyone tried to get them working instead of


while (1) printf ("no support in DOS no need in DOS get Linux there is no BLOAT in Linux DOS doesn't need more than 4gb")


Also, filesystems don't need any hardware support, and the FAT crap mess is there, why? Because nobody ever tried to fix it, or even missdeclares it as a "feature" :-(

No real mode, no Ring0, no physical memory, no bloat avoidance, ... :-(

Examples + evidence please.

Indeed. But where are all the new games ???

Don't forget APIC :-(

it still is and still is obsolete

DPMS - another superset of DR-EMM386 (only)

DUGL - a graphics and GUI library for DGJPP and FreeBASIC

VESA - a software standard to access graph card with INT $10 from real mode and partially also from protected mode
