Adaptec 1540CP Installation Guide - Page 10

If you have multiple AHA-1540CP/1542CP host adapters in your computer, use the SCSI Disk Utilities to determine which host adapter you are configuring. Configure/View Host Adapter Settings The Configuration screen displays these options: Host Adapter Interrupt (IRQ) Channel, Host Adapter DMA Channel, Host Adapter SCSI ID, SCSI Parity Checking, DMA Transfer Rate, and Host Adapter SCSI Termination. Highlight an option and press Enter to select the value. Select SCSI Device Configuration to modify the following options for each device on the SCSI bus: Enable Synchronous Negotiation, Enable Fast SCSI, Enable Disconnection, Send Start Unit Command, and Include in BIOS Scan. You can set these options individually for each device on the SCSI bus. Select Advanced Configuration Options to modify the remaining advanced options as listed on page 3. Do not change these options unless you fully understand what they mean. SCSI Disk Utilities Select SCSI Disk Utilities from the Main menu to view a list of installed SCSI devices. When you select a device, the Utilities menu appears. Format Disk runs the Adaptec SCSI low-level format utility. Verify Disk Media scans the selected device's media for defects. If it finds bad blocks, it prompts you to reassign them. Host Adapter Diagnostics The Host Adapter Diagnostics option allows you to perform a Bus Master DMA test on your PC's memory. Not all PC systems are fully ISA compatible and properly support Bus Master DMA transferswhich are necessary for optimized performance under multitasking operating systems like OS/2, Windows 95, and NetWare. The diagnostic program performs a memory transfer test and then repeats the process. If the test fails, try changing the DMA transfer rate to a lower setting in 9
