HBA (Host Bus Adapter) 64KB Aid ver 1.0.5 is a simply utility that allows easy modification of the MaximumSGList in the Windows registry, allowing you to do data transfers over the standard 64KB size.
This application was written as a compliment utility for Tapewise, our Tape testing application.
HBA 64KB Aid is a very simple application that allows you to make minor modifications to the Windows registry. You are shown a list of detected HBA’s services (which includes SCSI/Fibre cards etc.) that are in the SCSI group along with the current maximum setting, and a list of devices that the service controls (Via expansion).
Once you run HBA 64KB Aid you will be shown a screen similar to above (Depending on installed HBA’s). Simply select a Service group row from the list, and you are given additional options :-
The additional options now available are :-
- New MaximumSGList value : Shows you the current value it is set to, and allows you to enter a new value (The actual size in KB is shown next to it). Please note that this option is only available to you if “Not set” is not checked.
- Not set : By checking this value, you are indicating that you want to delete any setting and use the Windows default.
- Save : Saves (or deleted if “Not set” is checked) the modifications to the registry. You are warned before any action takes place. NOTE: Settings do not take effect until you reboot the system.
- Cancel : Resets the settings to the current ones.
I have seen notes that on Windows 2003 Server, the maximum transfer rate is (Value-3)*4096 instead of (Value-1)*4096. I have been as of yet unable to confirm this, so any feedback on that is welcome.
HBA 64KB Aid was written for our own use to ensure that Tapewise could do block transfer sizes of over 64KB
The maximum value you can set is 255 which is increased by windows to allow 1MB transfers.
The lowest value you can set is 17, which is the lowest/system default.
Vista 64-bit support is not yet verified.
