A. Yes, you can set the StarPort driver to use different maximum request size. The settings can be changed at the registry key: [HKLM\CurrentControlSet\Services\StarPort\Parameters] Value ‘MaxBufferSize’ (DWORD) By default StarPort uses MaxBufferSize=65536 To apply changes just restart your initiator machine. Please keep in mind that changing of MaxBufferSize is global to all StarPort’s devices. So setting MaxBufferSize too small can lead to performance degradation for other devices accessed with StarPort (like hard drives, CD/DVD burners, etc).
