Modify the Windows NT Registry
Note
Before changing any values, we recommend
making a backup copy of the registry.
Changes
made incorrectly to the Windows NT Registry
will have disastrous effects.
You can modify Windows NT parameters through the registry using the format shown below.

Windows NT 4.0 Registry Parameters
The table below lists parameters that can be changed, allowable range of values, and factory
defaults.
AbortStatus = 0x
n
Values from 0x00 - 0xFF. Controls NT SRB error status for general
Abort conditions. Default = SRB_STATUS_BUS_RESET (0x0E)
which will not cause the current NT Class driver to throttle down
I/O performance after 4 of these errors have been received (on a
per-LUN basis).
ALTOV =
n
Values are in milliseconds from 1 to 15. Default = 15.
ARBTOV =
n
Values are in milliseconds from 500 to 10000. Default = 1000.
Represents FC_AL arbitration time-out prior to LIP.
Class =
n
Values from 0 - 2. Default = 2. Controls which Fibre Channel Class
will be used: 0 = Class 1, 1 = Class 2, 2 = Class 3.
EDTOV =
n
Values are in milliseconds from 500 to 10000. Default = 1000.
Represents error detect time-out value prior to LIP.
EnableDPC =
n
Values 0 or 1. Default = 0. 0 = process I/O completion at interrupt
