If the number format on the sticker is like xx-xxxxxx-Gxxx , then this is ATO2161 G-Series (Rev.G).

Please DO NOT download / upgrade the BIOS UNLESS your system has a BIOS-related issue. Flashing the wrong BIOS can cause irreparable damage to the system.

ATO2161 Dual Core BIOS Installation Instructions

You must use the "phlash16.exe " BIOS flash utility included in the .zip file and a boot disk to boot the system up.
Boot Disk - Refers to either a Windows 95 or Windows 98 boot disk. Other type of boot disk might load memory resident programs, which will interfere with the flash process. Make sure you hit the F5 key when the boot disk first starts running to make sure no other programs are loaded in the background without your knowledge
  • Flash the ATO2161 Dual Core BIOS using the following command: PHLASH16 /mode=3 /C /BBL biosfile.rom
  • Please replace "biosfile.rom" with the version of BIOS you are flashing to, for example, "hdama_dc209.ROM" for BIOS version 2.09
  • /BBL is to flash the BIOS boot blocks
  • /C is to clear CMOS

IMPORTANT: If you don't add the /c parameter, you'll need to clear CMOS manually.

 

To clear CMOS manually:

  • Turn off your computer.
  • Take off the power cord.
  • Short pin2 and pin3 with a jumper for a few seconds.
  • Replace the jumper on pin1 and pin2

The jumper is near the battery and pin1 is nearest the PCI slot.
IMPORTANT: If you don't take off the power cord, the CMOS may not be cleared.

 

Troubleshoot
In the rare event that something goes wrong (for whatever reason) and you end up with a "dead BIOS", where the board will not POST or show video after a BIOS update and after manually resetting CMOS, you can bring a dead BIOS back to life if you have a 2nd working ATO2161 (HDAMA) board. Simply take the ROM chip out of the working board and put it in the dead board and use it to boot the dead board. Then after the board is booted, remove the good ROM and put the dead ROM back into the board and use the flash tool to flash it. That should get it going again.

Recovery
In the rare event that something goes wrong, for whatever reason, and you end up with a "dead BIOS". Meaning, in the case where the board will not POST or show video after a BIOS update and after manually resetting CMOS, you can bring a dead BIOS back to life. Download
