Fortunately, the memory isn't on the ISA bus, so that's not a problem. However, the BIOS call that tells you how much memory is in the system uses a 16-bit return register, limiting you to 65536 Kb. Memory-mapped peripherals on the ISA bus are limited to the 16M address space. VESA local-bus vga cards are not.
