EMCO MSI Package Builder is an installation authoring tool designed to help administrators to create, maintain and distribute Windows Installer packages. It can be used to create MSI packages easily, to modify existing installations and to repackage setups from the EXE to MSI format.

EMCO MSI Package Builder is specially designed to repackage non-silent EXE installations into silent MSI packages and is one of the most capable packaging tools on the market. Using it you can easily convert installations into MSI packages. The program allows you to repackage complex installations, including those that deploy Windows services, drivers, etc. The program can package installations into MSI, App-V, MSIX/AppX formats.

EMCO MSI Package Builder: How to Create an MSI Package?

How to make MSI packages and what are the advantages of using EMCO MSI Package Builder? The application simplifies installation authoring by making use of the visual editor and changes tracking technology, which is used to generate installation project data. To create an MSI, you can certainly follow the traditional way and specify the installation resources and actions through the visual editor, but it is more efficient to use the Live Monitoring technology. How monitoring works

When monitoring is enabled, the application detects the file system and registry changes undertaken on a PC and uses them to build an MSI. You can make the required changes manually to get an installation that will reproduce them or monitor actions of the existing installations in order to convert them from the EXE to MSI format.

The innovative Live Monitoring technology saves you the complexity of manual MSI building. Create an MSI using a truly visual approach by performing the required installation actions on your PC. EMCO MSI Package Builder will track your changes and make an MSI file for you automatically. You can modify the installation by using the visual editor.

Convert EXE to MSI

An easy EXE to MSI repackaging helps you to convert legacy EXE setups that require interactive installation into the MSI format to prepare them for a silent remote deployment. It's possible to create an MSI from an EXE file in a fully automatic mode using the Live Monitoring technology, which is the most advanced technology available today.

Customize Existing Installations

Modification of third-party installations becomes possible with EMCO MSI Package Builder. Change existing installations to meet your needs by repackaging them into MSI packages and use the visual editor to apply changes. Combine installs into one MSI package and apply custom pre- and post-installation changes with only a few clicks.

Build MSI for Remote Installation

Get ready for a remote deployment by creating silent MSI packages. All produced setup files can be deployed onto remote PCs within a LAN by using Group Policy (GPO) or EMCO Remote Installer. All installations have preconfigured settings and can be deployed locally or remotely in a silent mode with no user interaction.

Monitor on the Local Machine or Existing VMs

You can repackage an installation and monitor the installation changes on the local machine, or use existing virtual machines for monitoring. The program supports VMs hosted on Hyper-V and VMware servers, so they can be connected by the program remotely to perform monitoring. The captured changes are used by the program to generate a package.

Use Command-Line Interface

To use the main features of the program, you can run commands provided by the command-line interface. The program allows you to perform monitoring on the local machine to capture changes and to generate packages in different formats. Using the commands, you can also export/import projects and sign the generated packages.

Message Signalled Interrupts (MSI) are an alternative in-band method of signalling an interrupt, using special in-band messages to replace traditional out-of-band assertion of dedicated interrupt lines. While more complex to implement in a device, message signalled interrupts have some significant advantages over pin-based out-of-band interrupt signalling.

Message signalled interrupts are supported in PCI bus since its version 2.2, and in later available PCI Express bus. Some non-PCI architectures also use message signalled interrupts.

Overview[edit]

Traditionally, a device has an interrupt line (pin) which it asserts when it wants to signal an interrupt to the host processing environment. This traditional form of interrupt signalling is an out-of-band form of control signalling since it uses a dedicated path to send such control information, separately from the main data path. MSI replaces those dedicated interrupt lines with in-band signalling, by exchanging special messages that indicate interrupts through the main data path. In particular, MSI allows the device to write a small amount of interrupt-describing data to a special memory-mapped I/O address, and the chipset then delivers the corresponding interrupt to a processor.[1][2][3]

A common misconception with MSI is that it allows the device to send data to a processor as part of the interrupt. The data that is sent as part of the memory write transaction is used by the chipset to determine which interrupt to trigger on which processor; that data is not available for the device to communicate additional information to the interrupt handler.[1][2][3]

As an example, PCI Express does not have separate interrupt pins at all; instead, it uses special in-band messages to allow pin assertion or deassertion to be emulated. Some non-PCI architectures also use MSI; as another example, HPGSC devices do not have interrupt pins and can generate interrupts only by writing directly to the processor's interrupt register in memory space.[citation needed] The HyperTransport protocol also supports MSI.[4]

Network

Advantages[edit]

Msi Network & Wireless Cards Driver Download For Windows 10 64-bit

While more complex to implement in a device, message signalled interrupts have some significant advantages over pin-based out-of-band interrupt signalling. On the mechanical side, fewer pins makes for a simpler, cheaper, and more reliable connector. While this is no advantage to the standard PCI connector, PCI Express takes advantage of these savings.

MSI increases the number of interrupts that are possible. While conventional PCI was limited to four interrupts per card (and,because they were shared among all cards, most are using only one), message signalled interrupts allow dozens of interrupts per card, when that is useful.[1]

There is also a slight performance advantage. In software, a pin-based interrupt could race with a posted write to memory. That is, the PCI device would write data to memory and then send an interrupt to indicate the DMA write was complete. However, a PCI bridge or memory controller might buffer the write in order to not interfere with some other memory use. The interrupt could arrive before the DMA write was complete, and the processor could read stale data from memory.[5] To prevent this race, interrupt handlers were required to read from the device to ensure that the DMA write had finished. This read had a moderate performance penalty. An MSI write cannot pass a DMA write, so the race is eliminated.[6]

MSI types[edit]

PCI defines two optional extensions to support Message Signalled Interrupts, MSI and MSI-X. PCI Express defines its own message-based mechanism to emulate legacy PCI interrupts.

MSI[edit]

MSI (first defined in PCI 2.2) permits a device to allocate 1, 2, 4, 8, 16 or 32 interrupts. The device is programmed with an address to write to (generally a control register in an interrupt controller), and a 16-bit data word to identify it. The interrupt number is added to the data word to identify the interrupt.[1] Some platforms such as Windows do not use all 32 interrupts but only use up to 16 interrupts.[7]

MSI-X[edit]

MSI-X (first defined in PCI 3.0) permits a device to allocate up to 2048 interrupts. The single address used by original MSI was found to be restrictive for some architectures. In particular, it made it difficult to target individual interrupts to different processors, which is helpful in some high-speed networking applications. MSI-X allows a larger number of interrupts and gives each one a separate target address and data word. Devices with MSI-X do not necessarily support 2048 interrupts.[3][8][9][10]

Optional features in MSI (64-bit addressing and interrupt masking) are also mandatory with MSI-X.

PCI Express legacy interrupt emulation[edit]

Windows

Msi Network & Wireless Cards Driver Download For Windows 10 Windows 7

PCI Express does not have physical interrupt lines, but emulates the 4 physical lines of PCI via dedicated PCI Express Messages such as Assert_INTA and Deassert_INTC. Being message-based (at the PCI Express layer), this mechanism provides some, but not all, of the advantages of the PCI layer MSI mechanism: the 4 virtual lines per device are no longer shared on the bus (although PCI Express controllers may still combine legacy interrupts internally), and interrupt changes no longer inherently suffer from race conditions.

PCI Express permits devices to use these legacy interrupt messages, retaining software compatibility with PCI drivers, but they are required to also support MSI or MSI-X in the PCI layer.

x86 systems[edit]

On Intel systems, the LAPIC must be enabled for the PCI (and PCI Express) MSI/MSI-X to work, even on uniprocessor (single core) systems.[11][12] In these systems, MSIs are handled by writing the interrupt vector directly into the LAPIC of the processor/core that needs to service the interrupt. The Intel LAPICs of 2009 supported up to 224 MSI-based interrupts.[12] According to a 2009 Intel benchmark using Linux, using MSI reduced the latency of interrupts by a factor of almost three when compared to I/O APIC delivery.[13]

Operating system support[edit]

In the Microsoft family of operating systems, Windows Vista and later versions have support for both MSI and MSI-X. Support was added in the Longhorn development cycle around 2004.[14] MSI is not supported in earlier versions like Windows XP or Windows Server 2003.[15]

Solaris Express release 6/05 added support for MSI an MSI-X as part of their new device driver interface (DDI) interrupt framework.[16]

FreeBSD 6.3 and 7.0 added support for MSI and MSI-X.[17]

OpenBSD 5.0 added support for MSI.[18] 6.0 added support for MSI-X.[19]

Linux gained support for MSI and MSI-X around 2003.[20]Linux kernel versions before 2.6.20 are known to have serious bugs and limitations in their implementation of MSI/MSI-X.[21]

Haiku gained support for MSI around 2010.[22] MSI-X support was added later, in 2013.[23]

NetBSD 8.0 added support for MSI and MSI-X.

VxWorks 7 supports MSI and MSI-X
