◆ executeCommand()

void openmsx::IDECDROM::executeCommand ( byte cmd )

overrideprotectedvirtual

Starts execution of an IDE command.

Override this to implement additional commands and make sure you call the superclass implementation for all commands that you don't handle.

Reimplemented from openmsx::AbstractIDEDevice.

Definition at line 139 of file IDECDROM.cc.

◆ fillIdentifyBlock()

void openmsx::IDECDROM::fillIdentifyBlock ( AlignedBuffer & buffer )

overrideprotectedvirtual

Tells a subclass to fill the device specific parts of the identify block located in the buffer.

The generic part is already written there.

Parameters

buffer Array of 512 bytes.

Implements openmsx::AbstractIDEDevice.

Definition at line 89 of file IDECDROM.cc.

◆ getDeviceName()

const std::string & openmsx::IDECDROM::getDeviceName ( )

overrideprotectedvirtual

Gets the device name to insert as "model number" into the identify block.

Returns: An ASCII string, up to 40 characters long.

Implements openmsx::AbstractIDEDevice.

◆ isPacketDevice()

bool openmsx::IDECDROM::isPacketDevice ( )

overrideprotectedvirtual

Is this device a packet (ATAPI) device?

Returns: True iff this device supports the packet commands.

Implements openmsx::AbstractIDEDevice.

Definition at line 78 of file IDECDROM.cc.

◆ readBlockStart()

unsigned openmsx::IDECDROM::readBlockStart	(	AlignedBuffer &	buffer,
		unsigned	count
	)

overrideprotectedvirtual

Called when a block of read data should be buffered by the controller: when the buffer is empty or at the start of the transfer.

Parameters

buffer	Pointer to the start of a byte array.
count	Number of bytes to be filled by this method. This number will not exceed the array size nor the transfer length.

Returns: The number of bytes that was added to the array, or 0 if the transfer was aborted (the implementation of this method must set the relevant error flags as well).

Implements openmsx::AbstractIDEDevice.

◆ readEnd()

void openmsx::IDECDROM::readEnd ( )

overrideprotectedvirtual

Called when a read transfer completes.

The default implementation does nothing.

Reimplemented from openmsx::AbstractIDEDevice.

◆ writeBlockComplete()

void openmsx::IDECDROM::writeBlockComplete	(	AlignedBuffer &	buffer,
		unsigned	count
	)

overrideprotectedvirtual

Called when a block of written data has been buffered by the controller: when the buffer is full or at the end of the transfer.

Parameters

buffer	Pointer to the start of a byte array.
count	Number of data bytes in the array.

Implements openmsx::AbstractIDEDevice.
