The INT 0x15, EAX=0xE820 function lists available memory, including a type.
Who defines those types? Or is it simply what BIOSes happen to be doing?
I found a list of types on
and would like to add a few types, like
Type 0xBAD1: BadRAM address/mask pair
Type 0xF1A5: Flash memory on the memory bus (so, NOR Flash)
and am in search for the best way to do this.
