As far as I can see, the wording on the page only says that the BIOS
ends at address 0xFFFFF, not that it starts execution at exactly that
address. So I think that page is ok.

Title:
Possibly inaccurate statement in PC Platform Docs
Status in QEMU:
Fix Released
Bug description:
The documentation at:
http://wiki.qemu.org/Documentation/Platforms/PC
Contains the statement that the processor, after reset, executes code
starting from address 0xFFFFF, corresponding to the last byte of the
single megabyte of memory in the old 8086 address range.
From my recollection of working in the microcomputer industry in the
late 1980's, execution actually starts in real mode at the start of
the last 16 bytes of addressable memory, at 0xFFFF0. Think about it -
if it's the last byte there's no room for an address operand to
accompany a 1-byte opcode.
