| The chart below lists the configuration options used by the DOS ODI driver. The options available for the PCnet driver (PCNTNW) and IPX protocol stack are shown in a sample NET.CFG file. Protocol stacks other than IPX may have additional options not listed here. Refer to that protocol stack's documentation for more information.
The PCnet driver (PCNTNW) has the following NET.CFG options available for ISA buses:
_ DMA
_ INT
_ PORT
_ NODE ADDRESS
_ FRAME
_ PROTOCOL (IPX)
_ FASTISA
_ BUSTIMER (5,6,7....13)
_ FDUP (OFF, UTP,AUI) (For Pcnet ISA II and PCnet PCI II only)
_ LINESPEED (Auto, 100F, 100H, 10F, 10H) (For Pcnet FAST and above only)
_ CDCOFF
FASTISA increases the performance of PCnet -ISA, PCnet -ISA+, and PCnet -ISA II in ISA machines by reducing the memory read and write cycle time from 450 ns to 350 ns. Older machines with slower memory may not support this mode.
BUSTIMER is for PCnet -ISA, PCnet -ISA+, or PCnet -ISA II on a PCI/ISA system only. Default is 6, the value 13 will get the best performance to PCnet ISA devices. Some systems require a lower value to avoid system problem with the floppy controller or another busmaster device.
FDUP only applies to PCnet -ISA II and PCnet -PCI II.
CDCOFF is for older PCI systems. If you saw CRC, drop the connection on the client system. Try to apply this keyword to see if the problem goes away.
All keywords may be used with the PCnet Family. For the PCnet -ISA+, PCnet -ISA II, PCnet -32, PCnet -PCI, PCnet -PCI II and PCnet -Fast devices, the DMA, INT and PORT are not required by the driver. In some cases, using these keywords would be a violation of the bus specification. Keywords listed in the Software Keywords section of the PCnet Family Software Driver Manual may also be used in the NET.CFG.
Sample #1: NET.CFG For PCnet -ISA Adapter Card Only
LINK DRIVER PCNTNW
;Change the DMA channel (DMA) to 7.
DMA 7
;Change the port (Base I/O address) to 340 hex.
PORT 340
;Change the interrupt (IRQ) TO 5.
INT 5
;Fast mode for ISA
FASTISA
Note: Comment lines are proceeded by a semi-colon (_;_) before each option line to indicate the option change.
Sample #2: NET.CFG For PCnet -ISA Adapter Card Only
(When Loading VLM.EXE)
LINK DRIVER PCNTNW
;Change the port (Base I/O address) to 300 hex.

INT 5
FRAME Ethernet_802.2
PROTOCOL IPX E0 ETHERNET_802.2
NetWare DOS Requester
FIRST NETWORK DRIVE = F
Note: Comment lines are proceeded by a semi-colon (_;_) before each option line to indicate the option change.
