Name three layers of ms-dos?
COMMAND.COM DOS Kernel BIOS
Why is BIOS accessed much less by Windows than it is by DOS?
Who told you? Windows uses more resources than DOS.. As we know that DOS can support less hardware than Windows and BIOS is the controlling system for integrated hardware, hence we can easily understand the utilization of DOS and Windows..
What is dos interrupt and bios interrupt?
There are more than one of them, the most important DOS interrupt is 21H. Consult the related link.
Compare DOS and BIOS call?
BIOS is the basic input output system provides a routine procedure, and use a program written in BIOS features simple, readable, and easy to transplant. PC-DOS is the most important operating system, as it includes nearly a BIOSdevice management, directory management and file management procedures, is a fully featured, easy to use collection of the interrupt routine. Using the DOS operatingusing the appropriate functions of the BIOS than the operation more simple and lessdependent on some of the hardware. BIOS functions and DOS functions are called by software interrupts. Need tointerrupt the function number before the call into the AH register, handle the function number into the AL register, besides, usually need to register in the CPU to provide specialized call parameters. In general, DOS or BIOS function calls, has the followingbasic steps: 1, the call parameters into the specified register; 2, for the function number, put it into the AH; 3, for sub-function number, put it into the AL; 4, according to interruption of DOS or BIOS interrupt call; 5, check the return parameters are correct. BIOS and DOS interrupt interrupt the relationship shown in Figure 9.1. In the memory system, starting from the address 0FE000H 8K ROM (read-only memory) is equipped with a BIOS (Basic Iuput / output System) routine. Reside in theROM BIOS in the PC series of different microprocessors to provide a compatible system POST, boot loader, the main I / O devices and the interface control processfunction modules to handle all system interrupts. Use BIOS calls that bring great convenience to the programmer programming, programmers do not understand the details of hardware operation, the direct use of instruction set parameters, and thencall the BIOS interrupt the sub-function, so programs written using simple BIOSfunction can be Reading is good, and easy to transplant. DOS (Disk Operating System) is the most important PC, operating system, which isprovided by the floppy or hard disk. Its two DOS BIOS module IBMBIO.COM andIBMDOS.COM the more convenient to use because more and DOS module providesthe necessary tests, the DOS operating the corresponding functions of the BIOS than the use of more simple operation, but the hardware DOS Dependence less.
What form of software can also called firmware?
That'd be software installed directly onto a piece of hardware which is the operating code for that piece of hardware. For example, a hardware RAID controller might have firmware on it that controls its operation.
What role dos marijuana play in the ecosystem?
a bad role
What is the role of flashing BIOS?
Flashing the BIOS (basic input/output system) is what you would do if you were to modify your BIOS. Flashing it simply means the act of modifying the way it runs.
What role bios plays in the computer?
It boots up the system.
Is it possible to install Windows or DOS on a normal phone?
No. Almost no phones contain x86 processors, and those that do not have a traditional IBM-compatible BIOS, so they cannot run Windows or DOS.
Will I lose bios memory in my desktop computer if I take out the battery?
what is the role of BIOS? why is it important for it to keep its memory after the computer is switched off?
How do you restart Windows XP to dos?
If your laptop will stay on in DOS mode then update your BIOS
If a newer version of your BIOS exists and you computer dose not have an operating system installed yet Is there another method of performing this upgrade that you might employ?
Many motherboards still have BIOS updates available as MS-DOS programs. These can be run from an MS-DOS boot disk without a permanent operating system installed. Alternatively, the motherboard may support a "recovery mode" that flashes the BIOS from an image stored on a floppy disk. This is normally used to recover from a bad flash but can also be used to update.
