Panel Type Initialization
The VGA BIOS will issue an INT 15h function call during POST. This function call allows
the system BIOS to specify the panel type to the VGA BIOS. The system BIOS should get the
panel type from GPI pins before the VGA chip initializes, and pass this information to VGA
BIOS through INT 15 Function 5F00h.

3.3.4 Enhanced IDE
The system BIOS can support 4 IDE devices on two controllers up to 12GB in capacity. The
BIOS supports Ultra DMA 33 and automatic configuration of drives using both the LBA and
CHS large drive re-mapping method. In addition to supporting standard drives through an
auto-configuration process that does NOT require user involvement or confirmation. The
system should automatically do this at POST time in a way that is transparent to the user. If a
drive is connected to the bus, the drive should be automatically recognized, configured and
available for use under MS-DOS.
Ultra DMA
Ultra DMA/33 is a new physical protocol used to transfer data between an Ultra DMA/33
capable IDE controller and one or more Ultra DMA/33 capable IDE devices. It utilizes the
standard Bus Master IDE functionality and interface to initiate and control the transfer. Ultra
DMA/33 utilizes a “source-synchronous” signaling protocol to transfer data at rates up to 33
Mbytes/sec.
