Vesa bank

Unknown

Hey...

I am trying making a procedure that makes a line. I am making it in 640x480x256 (mode 100h). I know that mode 100h have 4 banks, but how many lines is each bank.

I am wondering, why mode 101h requires 320kb memory and mode 100h only requires 256kb. The only difference is that, mode 101h has 5 banks and mode 100h has 4 banks.



Thanks...
