Bochs VBE Extensions: Difference between revisions

In order to change any of the registers (with the logical exception of VBE_DISPI_INDEX_ENABLE), the VBE extensions must be disabled first. To do so, write the value VBE_DISPI_DISABLED (0x00) to VBE_DISPI_INDEX_ENABLE (4). The changes are not visible until the VBE extensions are enabled again. To do so, write the value VBE_DISPI_ENABLED (0x01) to the same register (see also note below on enabling the LFB below).
