The disk was supplied with the computer, and if it was lost the system settings could not be changed. The BIOS was hard-coded to boot from the first floppy drive, or, if that failed, the first hard disk. In , Glenn Ewing approached me with a problem: This question has been asked before and already has an answer. How to find Windows 8 product key? SLICO does away with this problem completely. This is a variant of the accepted answer giving you a much more user-friendly output, easier to read and copy.

The motherboard BIOS typically contains code to access hardware components necessary for bootstrapping the system, such as the keyboard, display, and storage.


Efficient graph-based image segmentation. If you want a full Geant4 setup, I recommend running the Configure script. InGlenn Ewing approached me with a problem: I believe there’s more to embedded licenses than the actual key.

In most modern BIOSes, the boot priority order of all potentially bootable devices can be freely configured by the user through the BIOS configuration utility. It had a century bit which allowed for manually changing the century when the year happened.

Views Read Edit View history. Superpixels are becoming increasingly popular for use in computer vision applications. Unsourced material may be challenged and removed. Anyone who could switch on the computer could boot it. Permalink Sep 19, Some modern motherboards are including even bigger NAND flash memory ICs on board which are capable of storing whole compact operating systems, such as some Linux distributions.


Volume 8, Issue 6. This is a variant of the accepted answer giving you a much more user-friendly output, easier to read and copy.

In other projects Wikimedia Commons. Windows GUI based executable. Bob Fraley, Edited by: Some BIOS implementations allow overclockingan action in which the CPU is adjusted to a higher clock rate than its manufacturer rating for guaranteed capability.

Also, when errors occur at boot time, a modern BIOS usually displays user-friendly error messages, often presented as pop-up boxes in a TUI style, and offers to enter the BIOS setup utility or to ignore the error and proceed if possible. The same shell window should be used throughout the installation process in order to preserve the environment variables.

Before the operating system’s first graphical screen is displayed, input and output are typically handled through BIOS.

BIOS – Wikipedia

In modern personal computers running modern operating systems the BIOS is used only during booting and initial loading of system software. BIOS services are not used by modern multitasking operating systems after they initially load, so the importance of the primary part of BIOS is greatly reduced from what it was initially. You still need to setup the environment accordingly.

An extension ROM could in principle contain an entire operating system or an application program, or it could implement an entirely different boot process such as booting from a network. In modern computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard.


Windows command line based executable. Option ROMs normally reside on adapter cards. As such the bless utility no longer supports the –legacy switch, and prints “Legacy mode not supported on this system”.

Flash chips are programmed and re-programmed in-circuit, while EPROM chips need to be removed from the motherboard for re-programming. At the time I setup the device SP, it is easier and shorter to just unconditionally set up a new stack. When we failed to produce an operating system in a timely manner, Glenn started talking with Gary about CPM For example, an IBM PC might have either a monochrome or a color display adapter using different display memory addresses and hardwarebut a single, standard, BIOS system call may be invoked to display a character at a specified position on the screen in text mode or graphics mode.

We introduce a novel algorithm called SLIC Simple Linear Iterative Clustering that clusters pixels in the combined five-dimensional color and image plane space to efficiently generate compact, nearly uniform superpixels.
