I Method:

   the iSCSI ROM README.

**NOTE:

2) Upon booting to windows OS after installation, user will be prompted to 
   install iWARP driver. iWARP is not supported with the current package. To 
   disable iWARP go to VBD parameter and disable the iWARP Function

** For more information please refer to "iSCSI_boot_userguide.pdf"

Multipath I/O settings
----------------------------------------

As per the following KB article from Microsoft we recommend to set following 
registry keys to following values when Chelsio iscsi initiator is used along 
with MPIO for Windows 2008 SP2 and Windows 2008 R2.

http://support.microsoft.com/kb/972324/EN-US

Set 
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\mpio\Parameters\UseCustomPathRecoveryInterval to 1

Set 
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\mpio\Parameters\PathRecoveryInterval to 30.

It handles the MPIO scenario where the transient error on a IO path was so brief,
that PnP did not register the fact that the path went away and then came back. 
By setting the above values, the path recovery attempt will happen before the 
pseudo-LUN gets removed. If the path is detected back online, the pseudo-LUN is 
saved from removal. 



5.Support Documentation
================================================================================

The documentation for this release can be found in the 
<system_drive>\Chelsio\doc\ directory after installing chelsio iSCSI driver 
InstallShield.

- iSCSI_boot_userguide.pdf
- README.txt
