MiniSCSI 1350 User's Guide Improving Overall Performance Following are some tips on improving the performance of the MiniSCSI 1350: s Ensure that the CMOS setting configuration for the parallel port and the setting in the Device Manager are the same. s Ensure that there are no Port Base and IRQ clashes with other installed devices such as Sound Cards. s If the parallel port supports EPP, ensure that the parallel port mode in the system CMOS is set for EPP. s To step up the system performance, in the Control Panel, select System, select the Performance tab, click on File System, ensure that the Performance is set to Full. s Select the Trouble Shooting tab and ensure that the Write Behind Cache is enabled. These are usually the default settings. s The MiniSCSI 1350s are programmed to give maximum performance for the following parallel port Port Base and IRQ combinations: 378h and 3BCh and IRQ 7 Port Base and IRQ combinations other than these are likely to slow down the performance. s Ensure that the total cable length does not exceed 3 meters and that no more than 7 devices are attached. For optimum performance we recommend attaching only 4 devices. 12
