(1) When there is newer bios revision. Should I update it?
|
|
If the system is running fine, We recommend not update bios unless, bios support new cpu code, and debug problem.
|
|
|
|
|
|
(2) How do I update my bios for the board?
|
|
|
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 (HDAMA) 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, "HDAMA182.ROM" for BIOS version 1.82
- /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

Heatsink and CPU installations
|
|
|
|
|
|
The ServerBoard accommodates AMD Opteron micro-PGA Socket 940 processors at 1600 MTs (MegaTransfers per second). You must first insert a CPU into CPU socket 0 (CPU0) before installing one in CPU socket 1 (CPU1).
|
|
|
|
This section outlines how to install a CPU into the ServerBoard
|
- Locate Pin 1 on the CPU socket and Pin 1 on the CPU itself.
- Lift up the lever on the CPU Socket 940. Then line up Pin 1 on the CPU with the Pin 1 marking on the socket before inserting the CPU into the Socket 940. Check that the CPU is flush in the socket, and lower the lever to lock the CPU in place.
|
|
|
- Apply Thermal Compound (Thermal grease) to the top of the CPU.
- Mount the Heatsink on top of the installed CPU by attaching it to the motherboard with the included screws (first on one side, then the other).

Symptom Checklist
|
|
Use this chart for more detailed information about some common problems that occur during assembly and in the mainetnance of systems.
|
|
|
Symptom
|
Check Point
|
|
No Power (FAN is not spinning)
|
* Make sure that no short circuit exists between the mainboard and chassis
* Check that all jumpers are set to their default positions.
* Check that the 115V/230V switch on the power supply is properly set.
* Check that the CPU is properly inserted in the CPU socket.
* Check that the power connector of the CPU fan is plugged in the correct position.
* Turn the power switch ON and OFF to test the system.
* Check the power of the battery on the mainboard.
(In general, the battery voltage is around 3VDC)
|
|
Able to power ON the system (FAN is spinning), but NO screen display.
|
* Disconnect and remove all components from the mainboard except for the CPU,memory modules, and the CPU fans.
* Check that the memory is Registered ECC DIMM. Refer to Appendix A: Recommended Memory Modules or contact your authorized dealer for a list of qualified memory vendors and models.
* Check that all jumpers are set to their default positions.
* Clear the CMOS through the Clear CMOS header.
* Check that the onboard VGA port and the monitor are properly connected.
* Check that you are using a 400 FSB CPU and PC2100/PC2700 (DDR266/DDR333) Memory modules in the ServerBoard. If not, change the CPU to 400 FSB or memory to PC2100/PC2700 (DDR266/DDR333) and try to power ON the system again.
* Use the onboard speaker to aide in determining the problem.
|
|
Memory Error(s)
|
* Check that the memory DIMM modules are inserted properly into the DIMM sockets.
* Check to see if different speed memory modules are mixed in and used in the ServerBoard memory banks. Verify that the BIOS setup is configured for the fastest speed of RAM used. accelerTECH recommends that you always install the same speed DDR RAM in your system.
* Make sure all your memory modules in the ServerBoard are compliant with the PC2100/PC2700 (DDR266/DDR333) Specifications and that they appear either in
Appendix A: Recommended Memory Modules or on your authorized dealer's Qualified Vendor's List of Memory Modules.

POST Errors and Beep Codes
|
|
|
|
PhoenixBIOS 4.0 Release 6.0
|
|
When you turn on or reset an IBM-compatible PC, the BIOS first performs a number of tasks, called the Power-On-Self-Test (POST). These tasks test and initialize the hardware and then boot the Operating System from the hard disk.
|
|
|
|
At the beginning of each POST task, the BIOS outputs the test-point error code to I/O port 80h. Programmers and technicians use this code during troubleshooting to establish at what point the system failed and what routine was being performed. Some motherboards are equipped with a seven segment LED display that displays the current value of port 80h.
|
|
|
|
For production boards which do not contain the LED display, you can purchase an installable “Port 80h” card that performs the same function. If the BIOS detects a terminal error condition, it issues a terminal-error beep code, attempts to display the error code on the upper left corner of the screen and on the port 80h LED display, and halts POST. It attempts repeatedly to write the error to the screen. This attempt may “hash” some CGA displays.
|
|
|
|
If the system hangs before the BIOS can process the error, the value displayed at the port 80h is the last test performed. In this case, the screen does not display the error code.
|
|
|
|
Terminal POST Errors
|
|
There are several POST routines that require success to finish POST. If they fail, they issue a POST Terminal Error and shut down the system. Before shutting down the system, the error handler issues a beep code signifying the test point error, writes the error to port 80h, attempts to initialize the video, and writes the error in the upper left corner of the screen (using both mono and color adapters).
|
|
|
|
The routine derives the beep code from the test point error as follows:
|
|
1. The 8-bit error code is broken down to four 2-bit groups.
2. Each group is made one-based (1 through 4) by adding 1.
3. Short beeps are generated for the number in each group.
Example:
Testpoint 16h = 00 01 01 10 = 1-2-2-3 beeps
|
|
|
|
POST Task Routines
|
|
The following is a list of Terminal Test Point codes written to port 80h at the start of each routine, the beep codes issued along with the terminal errors, and a description of the POST routine. Unless otherwise noted, these codes are valid for PhoenixBIOS 4.0 Release 6.0.
