Appendix C: Using Advanced Configuration Parameters ● 50 7 Select the Add key from the Edit menu; type Device in the Key Name edit box. Leave the Class edit box blank. To specify a certain SCSI card, append Device with the number of the SCSI card. For example, type Device0 for the first SCSI card, Device1 for the second, and so on. If you omit the SCSI card number, the configuration information applies to all Ultra320 SCSI cards. 8 Click the Device key. 9 Select Add Value from the Edit menu. In the Value Name edit box, enter one of the valid parameter values. Make sure to enter the appropriate data type for the value. To enter additional values, repeat Step 8 and Step 9. Note: Changes made with the Registry Editor do not take effect until you shut down and then restart your system. Using Driver-specific Parameters To use the Registry Editor to enter adpu320m.sys driver-specific parameters that affect the configuration information for Adaptec SCSI PCI device drivers, follow the instructions below. A list of valid parameters follows: Note: The following parameters are case-sensitive and must be entered exactly as shown. When entering multiple parameters, each parameter must be separated by a space. ● /MAXTAGS=nnn-specifies the tagged command queue depth per target. If a number is not specified, the tagged queue depth defaults to 32. Valid values are 1-255. The data type for this value is REG_SZ. ● /INSTR_ERRLOG_Z=nnn-sets the maximum number of error log entries, if / INSTRUMENTATION is enabled. If a number is not specified, the maximum number or error log entries defaults to 32. Valid values are 0-127. The data type for this value is REG_SZ To enter driver-specific parameters: 1 Select Run from the Start button. 2 Type regedt32, then press Enter. 3 Open the registry list to the following location: \HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\adpu320 \Parameters\Device If the Parameters\Device keys already exist, skip to Step 10 below to begin entering parameters. If the keys do not yet exist, you need to create them by continuing with Step 4. 4 Click the adpu320 key. 5 Select the Add Key from the Edit menu; type Parameters in the Key Name edit box.
