DOS-based BIOS Flash Utility

The DOS or DRMK (Dell Real Mode Kernel)-based BIOS flash utility for each platform can also be found

at the Dell support website. Note that you must have DOS bootable media, such as a USB key. To

update the BIOS using this utility, perform the following steps:

1. Browse to the location where you downloaded the file.

2. Update the name of the file to DOS-recognizable format (8.3). If you do not update the

filename to 8.3 format, the file name will be truncated to 8.3 format.

3. For more information on the 8.3 format, refer to http://en.wikipedia.org/wiki/8.3_filename.
