Optimizing Performance Try enabling Send Start Unit Command for one peripheral at a time, rebooting each time to make sure each SCSI device works properly. (Some older disk devices do not support this option and may malfunction if they receive the command.) Note The Send Start Unit Command has no effect if the host adapter BIOS is disabled. DOS/Windows Performance Adaptec's EZ-SCSI I/O Operating Environment Software is designed not only to simplify installation of device drivers under DOS, but also includes ASPI management software to provide Virtual DMA Services (VDS) support and enhanced Windows support. The drivers that are installed will give DOS users the best performance possible under not only DOS, but Windows. Ì Adaptec AHA-2740 Series User's Manual Stock Number: 510381-00 / Rev.
