NextMove PCI and Non-Micorsoft Operating Systems

doDeviceClose

This function releases any resources which had been taken by the class.

getDeviceOpen

This function must report whether the class has control of any resources it requires to communicate with the

controller and whether that controller is physically present. In the MySimplePCI example this reports whether it

can communicate with device driver. In Windows 95 on instance of the device driver is created in memory per

device it finds, so if the device driver instance exists in memory, the NextMove PCI is present. Under Windows

NT, there is one device driver to handle all NextMoves, so the device driver must be interrogated to find if that

card number is present.

doDeviceOpen

This function must take any resources required to communicate with the controller. In the MySimplePCI

example, this creates a handle to the device driver.

getLong

This function must read from DPR (block 3 in section 5.2 ) This may take the form of (as in the MySimplePCI

example) instructing the device driver to perform the task. The read should be a simple 32 bit read from the

memory address the DPR has been mapped into (Block 3).

internalSetLong

This function must write to DPR (block 3 in section 5.2). This may take the form of (as in the MyMySimplePCI

example) instructing the device driver to perform the task. The write should be a simple 32 bit write to the

memory address the DPR has been mapped into (Block 3).

PLXRead

This function must read from the PLX chip (Block 3 in section 5.2) This may take the form of (as in the

MySimplePCI example) instructing the device driver to perform the task. The read should be a simple 32 bit

read from the memory address the PLX chip has been mapped into (Block 1).

PLXWrite

This function must write to the PLX chip (Block 3 in section 5.2 ) This may take the form of (as in the

MySimplePCI example) instructing the device driver to perform the task. The write should be a simple 32 bit

write to the memory address the PLX chip has been mapped into (Block 1).
