Intel® I/O Acceleration Technology driver conflict with Windows* 2003 R2 SP2

When using Microsoft* Windows Server* 2003 R2 SP2 with the Intel® I/O Acceleration Technology (Intel® I/OAT) drivers included in the LAN driver packages versions 12.2 or 12.3, the user may receive a STOP error 0x000000C5 and 0x0000007E during boot or shutdown. The issue appears approximately once every 5 boots/shutdowns.

This is due to a change by Microsoft in their NetDMA API in service pack 2 for Windows Server* 2003.

The Intel® I/OAT driver issue was corrected in the Intel® LAN driver package 12.4.

The following workarounds are possible:

  • Disable Intel® I/OAT in the BIOS of your Intel® Server Board
  • Upgrade your LAN Drivers to version 12.4 or later

Operating System:

Windows Server 2003 *, Windows Server 2003 Standard Edition*
