I'm not sure exactly what you want, but I'm guessing that you cannot boot the laptop even into BIOS mode because the BIOS is corrupt.
Which laptop?
Most laptops (actually, most BIOSs) have an emergency recovery mode whereby it is possible to force a BIOS update even if the system cannot boot.
Try this:
Download the required BIOS file; let's call it x.exe
Extract the HDR file from the x.exe with: "x.exe -writehdrfile". This will give a file x.hdr
Copy x.hdr to a formatted diskette, perhaps on a USB-diskette (might even work on a pen drive)
Rename x.hdr according to the list below
Unplug the adapter and remove the battery from the laptop
Hold "END" down on the keyboard while you plugin the Adapter
The battery light should come on red
Release "END" - the laptop power should up
Wait while the diskette is read, this might take some time (you'll hear it)
The laptop should shut down or restart itself
Job done!

Thanx for your reply Mr. FoxyRick. But i have treid given command and programme the ROM IC with ROM programmer instead of Folppy diskette but didn't working.

The instructions that I gave are for using the emergency recovery file; I have no idea if you can simply write that file directly to the chip. What file size did you get - did it match the chip's size?
Can you verify that the file has been written correctly to the chip with your programmer? Did you use SPI, or pull the chip from the board and plug into your programmer?
You must use adequate programator for that eeprom in that Dell.
Needed informations: Dell model and exact text from EEPROM chip.

Dell System Beep Codes
If an error occurs during startup that cannot be reported on the monitor, your computer may emit a beep code that identifies the problem. The beep code is a pattern of sounds: for example, one beep, followed by a second beep, and then a burst of three beeps (code 1-1-3) means that the computer was unable to read the data in NVRAM.
If a beep code is emitted, write it down on a copy of the Diagnostics Checklist and look it up in the following table. If you are unable to resolve the problem by looking up the meaning of the beep code, use the Dell Diagnostics to identify a more serious cause. If you are still unable to resolve the problem, contact Dell for technical assistance.
If the computer loses power and beeps constantly when you turn it back on, the BIOS is probably corrupted. See "BIOS Recovery Utility" for information on restoring the BIOS.
