VGA BIOS

[Dmitry Zavyalov]

Hello All,

I've found a trouble copy the VGA BIOS from standard 512kb flash to
  the 0xc0000 memory. When I read the ROM the data reading via 4k
  blocks (1st block - ok, 2nd block - copy of block 1, 3rd block - ok,
  4th block - copy of block 4). Looks like it's some hack to work with
  MTD devices (that uses only 12 address lines on ISA bus and works
  trough window). How to disable it? (i440bx/mx chipset).
