Registry Interface.txt Driver Update Utility

SsInstal - Contains all driver registry information
ErrorControl - Should be 1
Group - Should be "Extended Base"
Start - Should be 2 for Boot start
Type - Should be 1

LogLevel - This value does not get put in by the installation
program. It influences the amount of information written to the Event Log.
4 values are possible :
0 - no logging is performed
1 - only errors are logged
2 - errors and warnings are logged
3 - full information is logged
2 is the default for the driver, if no value is supplied.

Templates - contains all the templates for the supported cards
Bus1 - contains all ISA templates.
ComBaseAddressAlignment - always 8 for UART COM ports. This value has only got to be there,
when nComPorts is not 0.
LptBaseAddressAlignment - always 4 for UART LPT ports. This value has only got to be there,
when nLptPorts is not 0.
ClockFrequency - clock frequency in Hz
ClockFrequencyAdjustment - value which adjusts the clock frequency by dividing or
multiplying with the given value. Default is 1, which
does not chage the clock frequency. If the value is 0,
the driver defaults it to 1. Any other positive value
is the multiplyer for the clock frequency. Any other
negative value is made positive, and then the clock
frequency gets divided by this value. This value gets overwritten
by Parameters\Bus1\Cardx\ClockFrequencyAdjustment.
Description - Whatever you want call it (For example "Steve")
HardwareID - Hardware ID, used to uniquely identify the card.
nComPorts - Number of COM ports on the card
nLptPorts - Number of LPT ports on the card
PlxBaudClockType - If a card contains a jumper to configure the input clock frequency to
the UART, then this value has to be set. possible values are :
4 - for Jumper setable prescaler. PlxBaudClockDivisor has to
be present.
PlxBaudClockDivisor - Gives the divisor which should be selected by default. Possible
values are : 1, 2, 4 and 8.
RxTriggerLevel - Receive Trigger Level for 950 chips. (not yet implemented) Range 1-100
As an extra feature, if both, RxTriggerLevel and TxTriggerLevel, are
set to 0, the FIFOs are disabled. If the value is not there, the default
is set to 100 by the driver.
TxTriggerLevel - Transmit Trigger Level for 950 chips. (not yet implemented) Range 1-100
As an extra feature, if both, RxTriggerLevel and TxTriggerLevel, are
set to 0, the FIFOs are disabled. If the value is not there, the default
is set to 1 by the driver.
SoftTxLimit - The amount of characters transmitted on each TX empty interrupt
in percent. The allowed range is 1 to 100. Setting it to 1 garanties
that only 1 byte at a time is written to the FIFO. Setting it to 100
garanties, that the FIFO is filled up to its maximum on transmit.
The default, if the value is not present in, is 100.
UartType - This value should normally not be there. The Control Panel does
not need to update this value. It only exists for debugging purposes,
to overwrite the UART class to be installed on a port. For example :
when the card has 950 on it. Setting this value to 5, forces the
driver to use only 550 support. Possible value are :
4 - 450 UART
5 - 550 UART
7 - 750 UART
9 - 950 UART
AddressesBanked - Specifies, that the addresses passed to a card are not 8-byte blocks for each

consecutive order.

one IRQ for the whole card.

Bus5 - contains all PCI templates.
ComBaseAddressAlignment - always 8 for UART COM ports. This value has only got to be there,
when nComPorts is not 0.

when nLptPorts is not 0.
ClockFrequency - clock frequency in Hz
ClockFrequencyAdjustment - value which adjusts the clock frequency by dividing or
multiplying with the given value. Default is 1, which
does not chage the clock frequency. If the value is 0,
the driver defaults it to 1. Any other positive value
is the multiplyer for the clock frequency. Any other
negative value is made positive, and then the clock
frequency gets divided by this value.

example parameters should be added to ComPort3, then the ComPort
keys 1 and 2 need to be created, but do not need to contain
parameters

5 - 550 UART
7 - 750 UART
9 - 950 UART
NoSleepMode - If this value is not present (default) or is set to 0, the UART chip
goes automatically into sleep mode when idle. Setting this value to
anything but not 0 prevents the chip from doing so.

The cards underneath templates have to be in a particular order : On templates for cards with the same device ID, a lower
card numbers is not allowed to contain a higher revision number than a template with a higher card number. For Example :

Templates/Card Number : Device ID : Revision number :
Card1 60 0
Card2 60 3 // Not allowed, as card3 revision is lower !!
Card3 60 2
Card4 e0 1
Card5 60 4 // Allowed - other card types can be inbetween.

The card key under the Enum registry tree contains a Device Parameters key, which is used to comunicate
driver settings to the CardDLL control panel. When a device (card) is started on the SsInstal driver,
SsInstal creates the Device Parameters subkey, and adds values which represent the current state. The
CardDLL can read those values and build up the user-interface appropriately.
