RTX 8.1.1 Stability Update - 4/16/2009 - This release contains stability improvements to the loading and unloading of the RTX subsystem on XP systems. This update also contains additional functionality to set default behavior when devices are both MSI/MSI-X capable. Download Update

RTX 8.1 Updates

RTX Marvell NIC driver - 6/30/2010 - support for the Marvell chip set. The RTX Marvell Driver supports a subset of the Marvell Yukon PCI Express Ethernet controllers.Download Update

RTX 8.1 Service Pack 2 (8.1.2) - 8/18/2009 - This cumulative release contains all the features of the previous updates. Along with support for Visual Studio 2008. Download Update

RTX 8.1 Service Pack 1 (8.1.1) - 11/20/2008 - This cumulative release contains all the features of the previous updates. Along with support for XP Service pack 3. Download Update

CumulativeSubsystem2 - 10/2/2008 - This cumulative release contains all the features of the ‘CumulativeSubsystem’ update. Along with a fix for RtDeleteTime being unable to correctly terminate handler threads waiting on an SRI. Improvements to defeating Intel Speed Step in RTX Shared mode. Optimizations to local memory and heaps access, and C Runtime updates for Visual Studio 6.0 and 2005 that allow for private heap handles to cross DLL boundaries. Download Update

CumulativeSubsystem - 6/20/2008 - This cumulative release contains the new ‘Guard Page Update’ as well as the previous ‘IO APIC’ and ‘ProxyProcessProtection’ updates. The ‘Guard Page Update’ fixes performance problems that primarily affected Windows XP systems running on quad-core hardware platforms. Download Update

IO APIC - 3/24/2008 - On APIC systems, an IST that is masking or unmasking its signal must perform two writes as one continuous operation before it returns. Returning midstream opens up the potential for another ISR to interrupt in between the operations, causing the wrong bit to be masked/unmasked or the wrong vector number to be manipulated. Download Update

ProxyProcessProtection - 2/26/2008 - When a Win32 application linked to RTX stresses system resources by repeatedly creating and destroying numerous threads, unstable conditions can arise in the form of a blue screen, green screen, or exceptions. The Proxy Process Protection patch provides additional protection for internal structures that resolves this issue. Download Update

RT-TCPIP_0208_RawSockets - 2/22/2008 - This update provides fixes for RT-TCP/IP RAW Socket support. Download Update

RTX 7.1 Updates

RTX Marvell NIC driver - 6/30/2010 - support for the Marvell chip set. The RTX Marvell Driver supports a subset of the Marvell Yukon PCI Express Ethernet controllers.Download Update

RTX 7.1 Stability Update - 11/20/2009 - This Optional update contains stability improvements to the loading and unloading of the RTX subsystem on XP systems, along with fixes found in update RT-TCPIP_0407_71. Download Update

RT-TCPIP_0407_71 - 5/8/2007 - This update fixes the following issues. A call to the closesocket function always returned the WSAEINPROGRESS status message. The NumStartupEvents warning message appeared too often. The The Rt-TCP/IP stack reports a false collision if the Stack starts up while other nodes are trying to communicate to it. 82543gc driver Receive and Transmit interval delay values were changed to be inline with Intel recommend performance value. The Netmask parameter from the RtxTcpIp.ini file was not being applied correctly to the Ipv4 address. IPv6Address can now accept AUTO as a case-insensitive parameter. The patch adds the following functionality. Address Resolution Protocol (ARP) table is now configurable.The Rt82543gc driver had support added for use of location information.Subnetting can now be configured via the optional IPv6Prefix field.
