Adaptec 2944UW Installation Guide - Page 10

s If you are booting from the AHA-2944UW and you also have an ISA/EISA-based host adapter installed, you must disable the BIOS on the ISA/EISA-based host adapter. s If you are booting from an ISA/EISA-based host adapter and you also have an AHA-2944UW installed with a boot device connected, the ISA/ EISA-based host adapter will boot before the AHA-2944UW. s When running the SCSISelect utility, if the utility finds multiple AHA-2944UW host adapters in your computer, it displays the PCI bus number and PCI device number of each host adapter. To determine which of the host adapters SCSISelect is configuring, view the red LEDs on the host adapters as you move the highlight bar to different host adapters with the ↑ and ↓ keys. (The computer cover must be removed to view the LEDs.) Installing Device Drivers Some operating systems have an embedded driver for the AHA-2940UW. These drivers work fine with your AHA-2944UW; however, the most recent version of the driver should be installed in order for your AHA-2944UW to perform at its optimum level. If you purchased your AHA-2944UW in a kit, the kit includes the latest Adaptec EZ-SCSI® and Adaptec 7800 Family Manager Set software. s Adaptec EZ-SCSI-allows you to install software drivers for DOS/Windows® and several additional utilities. Refer to the EZ-SCSI Quick Reference. s Adaptec 7800 Family Manager Set-allows you to install software drivers for NetWare, OS/2, Windows® 95, Windows NT, and UNIX. Refer to the 7800 Family Manager Set User's Guide. You can order EZ-SCSI or the 7800 Family Manager Set by calling the number listed on page 11. Need Assistance? Troubleshooting Tips If you have a problem during installation, check these items first: s Have you installed the host adapter in a PCI Rev 2.0 compliant computer? s Are all SCSI devices powered? s Are all SCSI bus cables and power cables properly connected? Is pin 1 oriented correctly? s Does the host adapter and all devices on the SCSI bus have unique SCSI IDs? s Is pin-1 orientation maintained throughout the SCSI bus? (See Connecting Internal SCSI Devices on page 3.) s Are all devices on the SCSI bus terminated properly? s Does your system CMOS setup require you to enable PCI bus parameters? If so, see your computer's documentation. Check that IRQ channel assignment, board, and BIOS settings have been made. s Did you install your host adapter in a bus master PCI slot? Refer to your computer's documentation or try another slot. s Is parity checking consistently enabled or disabled on all devices on the SCSI bus? Computer Will Not Boot from a SCSI Disk Drive If both SCSI and non-SCSI disk drives are installed, then the non-SCSI disk drive is always the boot device. If the system has only SCSI disk drives, do the following: 1 Make sure the drive type in your computer's CMOS setup is set to No Drives Installed. 2 Make sure the boot hard disk SCSI ID corresponds to the Boot Target ID setting in SCSISelect. The SCSI ID is normally set with jumpers or switches on the drive. 3 If this does not solve the problem, back up all data on the SCSI hard disk and perform a low-level format with the SCSISelect Format Disk option. See the MS-DOS documentation for instructions on partitioning the disk after formatting. 9
