Project Log 2 2 LPC2148 USB Bootloader
Project Log 2 Project Title: USB MicroSD Card Reader EEE G512 Embedded System Design October 2018 Submitted by: Submitted to: Joy Parikh j 2016A3PS0136P Dr. Devesh Samaiya Rutwik Narendra Jain j 2015A3PS0726P 2 LPC2148 USB Bootloader The LPC2148 USB bootloader performs three steps: 1. The bootloader checks to see if a USB cable has been plugged in. If the LPC2148 detects the presence of a USB cable then it initiates a USB Mass Storage system. This will cause the target board to appear on any computer platform as a removable flash drive. The user can then seamlessly transfer files to the flash drive. In the background, the LPC2148 moves the user's files onto the SD card using the FAT16 file system. 2. The next thing the bootloader does is look for a firmware file (a file named FW.SFE). This file contains the desired operating firmware (in a binary file format) for the LPC2148 mi- croprocessor. If the bootloader finds this file on the FAT16 system then it programs the contents of this file to the flash memory of the LPC2148. In this way, the bootloader acts as a \programmer" for the LPC2148; and we can upgrade the firmware on the LPC2148 simply by loading a new file onto the micro SD card. 3. After performing the first two checks, the bootloader calls the main firmware. The main code should not even know that the bootloader was used and will run normally. 2.1 Details The USB device class used is MSCD (Mass Storage Class Device). The MSCD presents easy integration with PC's operating systems. -

Douglas A. Hamilton WINDOWS NT NT: The Greatest Thing Since Sliced Bread? T'S OFFICIAL. Windows unlike OS/2, is not the only product in the family. Right around the corner is the NT is finally out of the Chicago technology that Microsoft will be using in DOS 7.0 and Windows 4.0. Earli oven. The pricing has est betas for software developers are I scheduled for early fall and products been set and delivery dates based on it should be out in 1994. Chicago is a rewrite of the same Win32 have been promised. Those API (application programming interface) seen on NT. Compared with NT, it leaves promises (back in May) out the security (how many of us need government-certified C2 security on our were that the base system personal machines?), portability to RISC processors and the OS/2 character-mode would ship within 60 days and POSIX subsystems. And it wouldn't surprise me if Unicode support were trimmed out or if the networking were and the Advanced Server version would ship 30 days unbundled. What Chicago leaves in is 32- bit flat virtual memory, preemptive multi later. So there's every chance that by the time you read tasking, threads, pipes and semaphores all the really good stuff in Win32. That be this, there'll be piles of Windows NT packages at your comes Windows 4.0. Subtract the graphi cal user interface and you get DOS 7.0. local computer store. Is there anyone left who wonders why developers are so excited about NT? It's After a false rumor that Microsoft might price NT at not just because NT is expected to do ex tremely well. -

SWEDIN WEBER STATE UNIVERSITY DAVIS ABSTRACT In 2006, IBM ended their support of OS/2, closing the book on an ambitious effort to create a modern operating system for the personal computer. IBM and Microsoft released the OS/2 operating system in December 1987 to replace the primitive DOS with a more sophisticated, preemptive multitasking operating system for personal computers. This article argues that OS/2 failed because of the U.S.-Japan Semiconductor Trade Agreement of 1986, subsequent accusations of DRAM chip dumping by the United States, and the resulting tariffs on Japanese memory chips, led to a memory chip shortage that drove up memory prices. -

Windows NT Architecture Previous Screen Gilbert Held Payoff Windows NT Is a Sophisticated Operating System for Workstations and Network Servers
50-30-19 Windows NT Architecture Previous screen Gilbert Held Payoff Windows NT is a sophisticated operating system for workstations and network servers. This article helps network managers to understand the communications capability of workstations and servers running on Windows NT, and data base administrators to determine the suitability of this platform for a structured query language (SQL) data base server. Introduction Windows NT is a 32-bit, preemptive multitasking operating system that includes comprehensive networking capabilities and several levels of security. Microsoft markets two version of Windows NT: one for workstations—appropriately named Windows NT Workstation—and a second for servers—Windows NT Server. This article, which describes the workings of the NT architecture, collectively references both versions as Windows NT when information is applicable to both versions of the operating system. Similarly, it references a specific version of the operating system when the information presented is specific to either Windows NT Workstation or Windows NT Server. Architecture Windows NT consists of nine basic modules. The relationship of those modules to one another, as well as to the hardware platform on which the operating system runs, is illustrated in Exhibit 1. Windows NT Core Modules Hardware Abstraction Layer The hardware abstraction layer (HAL) is located directly above the hardware on which Windows NT operates. HAL actually represents a software module developed by hardware manufacturers that is bundled into Windows NT to allow it to operate on a specific hardware platform, such as Intel X86, DEC Alpha, or IBM PowerPC. HAL hides the specifics of the hardware platform from the rest of the operating system and represents the lowest level of Windows NT. -

Accessing Windows Applications from Unix and Vice Versa

This implies that even if eventually migrating to another environment, one still has to deal with coexistence among environments in the interim. In many com- panies it would make good business sense not to migrate legacy systems at all. Instead, it may be better to develop new systems in the desired en- vironment and phase out the legacy applications. The data created by the legacy applications is important and one must ensure that data can be ac- cessed from a new environment. Coexistence considerations are very im- portant in this case. Coexistence between Windows PAYOFF IDEA NT, UNIX, and NetWare deals with a Some users want applications they develop in number of related issues.

Introduction to MS-DOS
1.Introduction to MS-DOS : MS-DOS (Microsoft Disk Operating System) was the Microsoft-marketed version of the first widely-installed operating system in personal computers. It was essentially the same operating system that (Bill Gates's) young company developed for IBM as Personal Computer - Disk Operating System in 1981. Most users of either DOS system simply referred to their system as Disk Operating System. Like PC-DOS, MS-DOS was (and still is) a non-graphical line-oriented command- driven operating system, with a relatively simple interface but not overly "friendly" user interface. Its prompt to enter a command looks like this: C:\> MS-DOS does not care about anything called an icon, wallpaper or screen saver. Rather than being considered as a Graphical User Interface (GUI) MS-DOS is what is known as a command-line interface. You type commands on what is called the command line. MS-DOS is a single-user, single-tasking computer operating system. In spite of its very small size and relative simplicity, it is one of the most successful operating systems that has been developed to date. In DOS, a file name consists of eight character followed by a 3 character file extension. The size of a file is restricted to a 4 byte file descriptor, which limits a file’s maximum size to approximately 4 billion characters. The first release of DOS could not read or write to disk drives so users could only read and write to a floppy disc. DOS was not a state of the art operating system, even for its time. -
Chapter 1. Origins of Mac OS X
1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years.
