Value Value Entry ErrorControl 0x1 (normal) Start 0x3 (load on demand) Type 0x1 or 0x4 (driver or adapter)The following sections describe entries in the other areas of the Registry that contain configuration information for network adapter cards and their drivers, including:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
\Services\adapter name#\Parameters
These values should all be set by choosing the Network icon in Control
Panel. These value entries are provided here for informational purposes
only. For a list of default values for network adapter card settings, see
the table at the end of this section.
BusNumber REG_DWORD Number
Defines the bus number, beginning with 0 in the common case where the
computer has one bus type, whether it is ISA, EISA, MCA, or TurboChannel.
For the rare computer that has more than one bus, bus number 2 has the
value of 1, and so on.
This value should be maintained by the system. You cannot change it using
the Network dialog box in Control Panel.
Default: Usually 0 (depends on the installation)
BusType REG_DWORD Number
Specifies the bus type for the computer, as in the following list:
Value Bus type
0 MIPS (Jazz-Internal bus)
1 ISA bus
2 EISA bus
3 MCA bus
4 TcChannel bus
This value should be maintained by the system. You cannot change it using
the Network dialog box in Control Panel.
CableType REG_DWORD 1 or 2
Specifies the cable type as unshielded twisted pair (UTP=1) or shielded
twisted pair (NTSETUP=2), for Proteon 1390 adapter cards.
CardSpeed REG_DWORD 4 or 16 megabits per second
Specifies card speed as 4 or 16 megabits per second in hex (0x4 or 0x10),
for Proteon 1390 adapter cards.
CardType REG_DWORD Number
Specifies the card installed in the system. For some manufacturers, all
their network cards use the same driver, which checks the value of CardType
to determine the network card model number of the installed card. For
example:
CardType Network card model number value
DEC:
1 DEC100
2 DEC20x
3 DEC PC
4 DEC Station
5 DEC422
7 DEC101
Proteon:
1 Proteon 1390
2 Proteon 1990
Ungermann-
Bass:
2 UB PC
3 UB EOTP
4 UBPS
This value should be maintained by the system. You cannot change it using
the Network dialog box in Control Panel.
DMAChannel REG_DWORD 5, 6, or 7
Specifies the DMA channel used by the adapter card.
InterruptNumber REG_DWORD IRQ number
Specifies the interrupt level (IRQ) for the adapter card.
IRQ5 is a common choice (0x5).
IoBaseAddress REG_DWORD Number in hex
For some adapters, this entry specifies the I/O port base address as a
hexadecimal string. For other adapters, this entry specifies whether this
is the primary adapter card (1) or a secondary card (2).
MediaType REG_DWORD Number
Specifies the network type, as follows:
Value Network type
1 Ethernet
2 IBM Token Ring
3 ARCnet
4 FDDI network
5 Apple LocalTalk
This value should be maintained by the system. You cannot change it using
the Network dialog box in Control Panel.
MaximumPacketSize REG_DWORD Number
Specifies the maximum packet size that the IBM Token Ring adapter is
allowed to transmit. Use this parameter when sending data across bridges
that may have smaller packet sizes available on the destination network
than on the native network. You cannot change this parameter using the
Network dialog box in Control Panel.
MemoryMapped REG_DWORD 0 or 1
Specifies whether the adapter card is memory mapped.
MemoryMappedBaseAddress REG_DWORD Memory address in hex
Specifies the base memory (I/O) address used by the adapter card. This
number must match the card's memory address settings as specified by its
manufacturer.
NetworkAddress REG_SZ Number
Specifies the address the network adapter should use instead of the burned-
in address. For example, for the IBM Token Ring card, this value is
40000000203. You can change this value for Token Ring adapters using the
Network dialog box in Control Panel, but not for Ethernet adapters.
Transceiver REG_DWORD 1 or 2
Specifies the transceiver as External (1) or OnBoard (2). This value should
be 1 for a DEC/Intel/Xerox (DIX) connection.
The following table summarizes default settings for various card types.
