9.3. An alternative approach

If you don't know how much memory address space your motherboard decodes (and who does?), try using a "non-trivial" address, like 0x1FC00000, which has enough bits set to "1" to work on any motherboard, even if a few are not decoded. Keep in mind that using for example 0x10000000 may end up right on top of your system memory if the motherboard doesn't decode all upper address bits. You will only do that once.
