While it is possible to install the partition of a hard disk drive and installation therefrom of the correct operating system storage device driver in this manner, necessary storage device drivers. it is relatively a complicated and time consuming procedure, especially when installing operating system Software onto 15 hundreds of information handling system computer servers. BACKGROUND Floppy disk media has limited Storage capacity and thus may not be sufficient for some storage device drivers, and may not As the value and use of information continues to increase, have the capacity for storing more than one storage device at individuals and businesses seek additional ways to process a time. and store information. One option available to users are infor mation handling systems. An information handling system SUMMARY generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes, What is needed is a simple way to store at least one storage thereby allowing users to take advantage of the value of the device driver on a non-volatile storage medium that is not size information.

  • CS401 - Computer Architecture and Assembly Language Programming New Lecture Wise Questions& Answers for Final Terms Prepared by “Virtualians.Pk”
    CS401 - Computer Architecture and Assembly Language Programming New Lecture Wise Questions& Answers for final terms Prepared BY “Virtualians.pk” Lecture no 23: Q)what are the basic purposes/operations of the "BIOS vs DOS"? The BIOS software is built into the PC, and is the first code run by a PC when powered on ('boot firmware'). When the PC starts up, the first job for the BIOS is the power-on self-test, which initializes and identifies system devices such as the CPU, RAM, video display card, keyboard and mouse, hard disk drive, optical disc drive and other hardware. The BIOS then locates boot loader software held on a peripheral device (designated as a 'boot device'), such as a hard disk or a CD/DVD, and loads and executes that software, giving it control of the PC. This process is known as booting, or booting up, which is short for bootstrapping. DOS is an operating system for x86-based personal computers. It was the most commonly used member of the DOS family of operating systems Q)what is firmware? In electronic systems and computing, firmware is the combination of persistent memory and program code and data stored in it. Typical examples of devices containing firmware are embedded systems (such as traffic lights, consumer appliances, and digital watches), computers, computer peripherals, mobile phones, and digital cameras. The firmware contained in these devices provides the control program for the device. Firmware is held in non-volatile memory devices such as ROM, EPROM, or flash memory. Q)What is effect of SP when we push something in stack? Please explain in detail with example.

  • Flare-On 5: Challenge 12 Solution - Suspicious Floppy Disk
    Flare-On 5: Challenge 12 Solution - Suspicious Floppy Disk Challenge Author: Nick Harbour Background This challenge is framed as spy tool. You are told that we found a suspicious floppy disk that we suspect was given to spies to transmit secret messages. The spies were given the password but you weren’t. You need to figure out the hidden message. Running the floopy disk I recommend using the Bochs emulator for this challenge. You can start up a minimal x86 VM and add this disk image as a bootable floppy drive. Plus, the bochs image is directly loadable and debuggable with IDA Pro. If you load the floppy correctly with bochs you will see the screen shown in Figure 1 below. FireEye, Inc., 1440 McCarthy Blvd., Milpitas, CA 95035 | +1 408.321.6300 | +1 877.FIREEYE (347.3393) | [email protected] | www.FireEye.com 1 Figure 1: Bochs Initial Bootup Before we attempt to look closer at the contents of the floopy disk we can determine that the program that is launched in the boot sequence that appears to be prompting for the password is named infohelp.exe. If you hit Ctrl-C here it will terminate the batch job (autoexec.bat) and return you to the command prompt. Using the DIR command here will show you the list of files as shown in Figure 2 below. Figure 2: Floppy disk contents You can see from the file timestamps that many of the files on this disk are old. This floopy disk was originally generated with WindowXP using a “format /s” command to create a bootable floppy.
