Entries
Many parameters of the driver are controlled by registry entries. Normally there is no need
to change these keys manually because the setup procedure will do all the work for you.
Caution is given if you make any changes to the entries. Note down the old value before
modifying an entry, so you can restore it if you run into trouble.
The following section gives an explanation of all registry keys the driver will use. After you
have changed anything you should stop and then restart the driver by using the
Devices
Menu
in the
Control Panel
(Windows NT4 only) or reboot the system.
Driver Basic Entry
The name of the main driver key for the driver “ekf960si1" is
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ekf960si1
A few of the entries in the main driver key are common to all Windows NT4/2000 drivers.
Note that all values shown are hexadecimal values.
"
ErrorControl
"=dword:00000001 log errors and display a message box.
"
Type
"=dword:00000001 defines driver as kernel-mode driver.
"
Start
"=dword:00000002 automatic driver start on system boot.
The next ones are driver specific:
"
RxFIFO
"=dword:00000008 receive FIFO high watermark,
allowed values are 1, 4, 8, 14.
"
TxFIFO
"=dword:00000010 transmit FIFO size,
allowed values are 1-16.
"
DebugLevel
"=dword:C000001F debugging level, only useful for the checked
version of the driver.
Board Subkeys
For each installed I/O controller exists one “board_x” subkey, where x is a one based,
running index. Board subkeys must be consecutive. The board subkey contains the following
entries:
HKEY_LOCAL_MACHINE\...\ekf960si1\board_x
"
BOARD_NAME
"="CU1-CHORUS" name of the installed board.
