Flash Memory Writer Utility
1. Enable "Boot Block Programming" jumper as shown in section III.
2. Make sure the system is running in real mode. This utility will not operate if
the system is under protected mode or virtual mode. This means that you
cannot reprogram the motherboard BIOS under the Windows environment or
with any memory management software, including HIMEM.SYS. The fol-
lowing describes the easiest way run your system from real mode:
•
Boot from a floppy disk formatted with the "FORMAT A:/S" command with-
out creating CONFIG.SYS and AUTOEXEC.BAT files.
•
If you are using MS-DOS 6.x, you can bypass the AUTOEXEC.BAT and
CONFIG.SYS by pressing
played on the screen.
•
For Windows 95 users, press
Menu and then choose "Safe mode command prompt only"
3. You should copy the contents of the \FLASH directory to your hard disk drive.
Once you have accomplished the above tasks, you can run the Flash Memory
Writer utility. To run the utility, change to the directory containing
PFLASH.EXE and then at the DOS prompt, type:
PFLASH
The Flash Memory Writer Utility Screen:
IMPORTANT: Flash Type may also be "INTEL 28F001BXT." If "unknown"
is after "Flash type --," then this ROM chip is not programmable or not sup-
ported with the PnP BIOS and therefore cannot be programmed by the Flash
Memory Writer.
This screen provides three command options, which you can invoke by typing the
corresponding number of the command and pressing
describes each command:
