Installing Windows XP
Using Driver-Specific Parameters
Follow the instructions below to enter the registry values that affect
the configuration information for Adaptec SCSI PCI device drivers.
Each driver has its own key reference in the registry. In this example,
the Ultra320 key is used (adpu320). All SCSI host adapters
supported by the modified key are affected by the values you enter
here. 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. If a number is not specified, the tagged queue depth
defaults to 128. Valid values are 1-255. The data type for this
value is REG_SZ.
To enter driver-specific parameters:
1 Select Run from the Start button.
2 Type regedt32 and 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 to
begin entering parameters. If the keys do not yet exist, you need
to create them by continuing with Step 4.
4 Click on the adpu320 key.
5 Select Add Key from the Edit menu; type Parameters in the
Key Name edit box. Leave the Class edit box blank.
6 Click on the Parameters key.
