Looks a bit odd. The AMI header even on 286 boards should always be readable and is but have to load in PCem or MAME to see if it really is OK.
That is the way they've mapped the 8-bit rom onto 16-bit data bus. Some motherboards or ega cards would use two chips, this motherboard uses single chip, and the most significant address line is used as a "byte select" input. So lower half of the chip stores even bytes, the upper half stores odd bytes.
