iFLASH communicates with the existing BIOS to provide security mechanisms which reduce the
risk of tampering. It also communicates with BIOS to verify that the new BIOS image is compati-
ble with the existing image. This helps to prevent an incorrect BIOS from being placed into flash
memory.
iFLASH operates in three modes: Interactive Mode, Command Line Mode, and Recovery Mode.
Interactive Mode and Command Line Mode are used in normal situations. In these modes, the
user boots DOS and then executes the iFLASH utility. The keyboard and video monitor are avail-
able for issuing commands, locating files, and displaying progress. If iFLASH is interrupted by a
power failure or by user intervention, the flash ROM may contain an incomplete BIOS. Recovery
Mode provides a method to install the BIOS when the flash ROM has been corrupted.
For best results, iFLASH should run under DOS with no extended memory managers loaded.
The flash utility does not support DPMI environments such as Windows*, Windows 95, or Win-
dows NT*. Because the utility is written for DOS, it does not run under any other operating sys-
tem.
