Well, don't know why it is considered vga bios is 64k, memory map shows it 
is 32k in fact, further are ata rom and other devices, so we can skip 
everything behind 32k - which gives 2 bytes diff, at exactly the same 
locations as for me - 0x22 & 0x1CC(1C8 in your case, but looks as the same 
header still)
