System Memory
A 512 KB flash ROM is mounted on the IR-320 as the system ROM. After the BIOS is booted, the
system BIOS resides in the 64 KB area between 0F0000h and 0FFFFFh, and the video BIOS
resides in the 44 KB area (40 KB for the IR-300) between 0C0000h and 0CBFFFh. The area
between 0A0000h and 0FFFFFh in the system memory (main DRAM) is used for the shadow
memory and system management memory (SMM). The figure below is a system memory map.
