Andrew Boie 8240d7d07b x86: memory map BIOS Data Area ... Changes to paging code ensured that the NULL virtual page is never mapped. Since RAM is identity mapped, on a PC-like system accessing the BIOS Data Area in the first 4K requires a memory mapping. We need to read this to probe the ACPI RSDP. Additionally check that the BDA has something in it as well and not a bunch of zeroes. It is unclear whether this function is truly safe on UEFI systems, but that is for another day.
