How to Upgrade a New BIOS
You can install an upgrade BIOS for the
ROCKY-3705EV-R2
that you
can download from the manufacturer’s web site (
www.e-
icp.com.tw
). New BIOS may provide support for new
peripherals ,improvements in performance or fixes to addressed
known bugs.
BIOS Update Procedure:
1. Make a boot disk. Go to the DOS command prompt in MS-DOS
or Windows 9x and, with an available floppy disk in "A", type
"format A: /s" That will format the floppy and transfer the needed
system files to it.
NOTES:
A. This procedure will erase any prior data on that floppy, so
please Proceed accordingly.
B. Typically four files will be transferred, only COMMAND.COM
being visible when running a simple directory listing.
C. Please leave the diskette UN-write protected for the balance of
this procedure.
2. Download the BIOS upgrade file and awdflash.exe utility from a
ICP web site to a temp directory on your hard drive, or directly to
the floppy you made in step 1..
3. Copy ( BIOS file and awdflash.exe )two files to the boot floppy.
4. Reboot the system to the DOS command prompt using the boot
diskette you just made.
