How can I access dos from Windows XP

Question

How can I access MS DOS from win XP?

I want to upgrade my BIOS. (Downgrade, in fact.)

Answer 1

You can run DOSBox, which is an MS-DOS emulator. What are you trying to do?

Answer 2

Windows XP doesn't include MS-DOS. You can run an emulated DOS in DOSBox, but programs running inside that box won't have access to the BIOS.

You can make a DOS boot floppy from Windows XP, but it might not be able to access your hard disk, so that's no good if your BIOS image doesn't fit on a floppy.

The standard tool for BIOS upgrades (or downgrades, it's the same thing anyway) is FreeDOS. This is a free DOS clone, with enough basic support for modern hardware to get going. See for example Creating FreeDOS USB boot stick for BIOS flashing.

Answer 3

1.Open the "Start" menu from the taskbar. 2.Click "All Programs," then click the "Accessories". 3.Click "Command Prompt" to open the "Command Prompt" window. This is where MS-DOS commands can be entered and executed. 4.To access a list of commands, type "help" at the prompt and press "Enter." To learn how to use a specific command, type "help " and press enter.

Start -> Programs-> Accessories->command prompt

or

Start->Run->Type Command and Press Enter
