AH303A PCIe SC44Ge SAS Host Bus Adapter for Integrity Servers Support Guide, September 2009

Information fields on the Advanced Adapter Properties screen are as follows:
IRQ Indicates the Interrupt Request Line used by the adapter. This is
assigned by the system BIOS.
NVM Indicates whether the adapter has nonvolatile memory (NVM),
which is used to store configuration settings.
Chip Revision ID Indicates the revision ID of this adapter.
CHS Mapping Specifies how the Cylinder Head Sector (CHS) is mapped on a
disk that does not have existing CHS information: SCSI Plug and
Play Mapping, or Alternate CHS Mapping
SCSI Plug and Play Mapping Automatically determines
the most efficient and
compatible settings. This is
the default setting.
Alternate CHS Mapping Uses an alternate and
potentially less-efficient
mapping system that might
be required if a device is
moved between adapters
from different vendors.
Link Error Settings Indicates error conditions: Invalid DWORDs, Loss of DWORDs
Sync, Running Disparity Errors, and PHY REset Errors.
Invalid DWORDs Indicates the number of
invalid DWORDs received
(outside of PHY reset
sequences) since the last
PHY Link Error reset.
Loss of DWORDs Sync Indicates the number of
times that DWORD
synchronization was lost
since the last PHY Link
Error Reset.
