Recently in learning installshelled packaging. NET do software, where the MySQL database silent installation script will not write, I novice do not spray. In the way of not writing scripts, occasionally saw this advinceinstaller can be the. exe or. msi installation file repackaging to become a silent installer, the operation steps relatively simple, record to prevent forgetting, but also hope to have a good see can give a better way, to the bottom:Pre

The pci2.2 specification introduces MSI as a traditional line-based interrupt solution. Msi allows the device to allow interruption by writing a specific value to a specific address, rather than using a proprietary pin to trigger the interruption. Note that the destination address and data of a message are treated as vectors. Compared with traditional interr
1, to the official website to download your missing this file version of the EXE file.2, download 7-zip software (in Baidu download, relatively small).3, with 7-zip decompression this exe. A folder will appear with the approximate name Virtualbox-4.3.12-93733-win.4. Enter the cmd window. If not, Win+r key, enter CMD. Really not, to ask Baidu.5. Enter the folder where you unzipped the folder (that is, the folder where Virtualbox-4.3.12-93733-win is located). The drive letter toggles the label and
MSI appears in PCI2.2, and PCI 3.0 allows masks to be set for each interrupt
Msi-x appears in PCI3.0, relative to MSI, each device allows more interrupts, each interrupt can be configured independently
Basic functions
The device throws an interrupt by writing to a specific address
Compared to traditional pin-based PCI interrupts:

What is RAMDisk, I'm afraid I don't need to say that we all know. As for the advantages of RAMDisk, Baidu you can see because Ramsik has a fast read and write speed so "temporary files can speed up", "Install software can be opened seconds" and so on various optimization methods, more sharp speech also think that using RAMDisk can prolong the life time, protect t
The following two articles are very good articles on the RAMDisk file system in the ARM9 forumToday did a test, let Linux2.6.29.4 from the RAMDisk root file system to start a successful, summed up.It involves more content, a lot of things no longer detailed, for further study please consult the relevant information (Baidu or Google a lot).Development environment: Fedora 9Cross-compilation toolchain: ARM-LIN

Introduction in Linux, there is a special feature-initializing the memory disk initrd (initial RAM disk) technology, and the kernel supports compressed file system images. With these two features, we can enable Linux to initialize memory disks from an early stage.

Today, Kingston's 1g memory stick is ready. In addition to the original 1.5 m memory, a total of GB memory is allocated, and MB is used as the virtual hard disk. The swap files, temporary system files, and temporary webpage files are all placed on it.
It's really cool. It's faster to open files and browse the Internet, especially for memory-consuming software such as Photoshop, which is less likely to read hard disks. Previously used in this document
