Fields

reserved1

Reserved by NetWare®.

CsharingFlags

Flags that indicate which resources are shareable. Bit definitions are as follows:

Bit	Description
0x001	IODetached
0x002	IOSharablePort0
0x004	IOSharablePort1
0x008	IOShareableMem0
0x010	IOShareableMem1
0x020	IOSharableInt0
0x040	IOSharableInt1
0x080	IOSharableDMA0
0x100	IOsharableDMA1

Cslot

The slot or Hardware Instance Number (HIN) assigned to this adapter.

CIOPortsAndRanges

Primary port address and length, secondary port address and length.

CmemoryDecodeAndLength

It contains the physical address and length of the primary and secondary memory addresses. This is used when the adapter requires physical memory space to perform its function. See the MemoryConfiguration structure.

See ClinearMemory for the virtual address associated with these memory addresses.

CintLine

Primary and secondary interrupts associated with this adapter. Initialize to 0xFF if not used.

CDMAline

Primary and secondary DMA channels used for this adapter. Initialize to 0xFF if not used.

reserved2

Reserved by NetWare.

reserved3

Reserved by NetWare.

ClinearMemory

Virtual address associated with the physical address found in CMemoryDecodeAndLength.

CchannelNumber

Used for multichannel adapters. It holds the channel number of the Network Interface Circuit to use. Set this field to 0 if multichannels are not used.

CbusTag

The bus tag associated with this adapter.

CIOConfigVersion

The version of the IO_ConfigurationStructure.
