Title: Question about VESA graphics programming for DOS
Post by: ben321 on January 28, 2022, 12:34:10 AM

I know I can use the VESA (very high resolution) specification with "INT 10h" and the AX register set to 4F02h and BX set to the VESA video mode number you want. But what is the default memory address for video RAM in VESA mode? Is it the same as VGA, which starts at A0000h? Or is the starting address for VESA mode video RAM something completely different? I'd like to know, so I can write a VESA mode assembly program.
