Hello,
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
http://wiki.osdev.org/Detecting_Memory_(x86)#BIOS_Function:_INT_0x15.2C_EAX_.3D_0xE820
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.
Thanks,
-Rick
