EEPROM Update (Flash BIOS) VP / PC 300/700, Server 315-8638

  If a power failure occurs during a flash update, the system board may be unusable !

Be sure the FLASH-BIOS diskette has the WRITE PROTECT tab set to WRITE-PROTECT, before start flashing. (In some cases, WIN-95 is updating the Vendor-ID field of the flash diskette media, which is used by IBM for flashcode-ID-flags. If this happen you will see the message The diskette in drive A: is not a valid flash diskette)

•  For a BIOS PC 360-S150 Type 6598 update  go to the (below) BIOS-Update PC 360-S150 Procedure
•  For Aptiva 2136 SL-A update  see 2136 Flash BIOS update

It may be possible to install a FLASH BIOS for a specific machine type on a different machine type. e.g., it may be possible to install PC300-486 flash on a PC300 Pentium® system and vice versa or install PC700 flash on a 64xx. Once the incorrect flash BIOS is installed, and the system re - booted, the system board will no longer be functioning and there is no field procedure to reinstall the correct flash. The system board must be replaced !
If the flash diskette is not labeled, the most reliable method to determine what system it applies to, is to view the diskette volume label. The first two digits of the volume label define code's applicable machine type. Once you have determined first two digits on the diskette, compare it with the BIOS level reported in the Configuration/Setup utility before start with the flash install.

Security of EEPROM
The introduction of Flash EEPROM means that any software can potentially alter the microcode. Should this be an concern, then a physical jumper is available on the IBM PC 300/700 Series to disable the ability to write to the EEPROM.

When to Update 
You should apply the latest EEPROM update to your machine if:

•  You have a compatibility or defect issue identified as being addressed by a code change.
•  You have an unidentified or intermittent problem that may be influenced by the BIOS.
•  You need scheduled/controlled maintenance.

How to Apply an EEPROM Update  (Stand-Alone)

The following parameters are used when you want to update the Flash BIOS.
The default filenames are $IMAGES.US F for PC 300 Series systems and $IMAGEV.US F for PC 700 Series systems. The first two characters of the extension change for each country. The valid Countries are listed below: (The order of the parameters is NOT important). 

/BR Brazil
/DK Denmark
/FR French
/GR German
/IT Italian
/NL Netherland
/NO Norway
/PO Portugal
/SP Spain
/SU Finland
/SV Sweden
/US US English
/BE Belgium
/CE Canadian English
/CF Canadian French
/LA Latin America
/UK UK English
/SF Swiss French
/SG Swiss German
/BF Belgian - French
/AU Australian

The following parameters are part of the utilities of the Flash:

/U Unattended mode - no output is displayed
/R Reboot machine when done flashing
/P Planar S/N (ignored on machines with EEPROMs)
/B Box S/N
/M Machine Type/Model
/I Directory/Filename of the Flash file
/N Update VPD but do not use Flash file

Procedure 

1.  Power-off the 300/700 Series computer.
2.  Ensure that the Flash memory write protect jumper on the system board is set to the enable position.
3.  Ensure that Diskette Drive 0 is listed as the First Start-up Device in the  Start-up Options.
4.  Insert Update diskette into Diskette Drive 0.
5.  Power-On the 300/700 Series computer.
6.  Select a country and Press Enter
7.  The current Serial Number of the machine is displayed, with a prompt asking  you would like to update it. If this is a new machine, or the Serial Number is incorrect, answer Y  and enter the seven character Serial Number at the next prompt.
8.  The current machine Type/Model of the machine is displayed, with a prompt asking if you would like to update it.
9.  The Flash program in the computer, compares the current system board EEPROM level with that on the  diskette. If the two match it is assumed that a language update is to be done. In this case proceed directly to step d  below, otherwise continue at step a
   1.  Wait for the panel requesting confirmation that you wish to update the  EEPROM code level. Below is an example of the message:

        IBM PC 300 and 700 POST/BIOS Update Utility   The Current BIOS is a different level   Planar Level = N1KT54AUS   Disk Level = N1KT55AUS   Do you wish to Update (Y/N)

   2.  Reply Y to this
   3.  The machine will display a message:

        Auto-Reboot ENABLED

       Shortly after this the machine will reset and proceed with the usual power-On  sequence. The code update is complete. However the default language is US English.  Should any other language be required, leave the diskette in the machine and proceed..

   4.  Wait for the message:

        IBM PC xxxx Language Update Utility

   5.  Enter the appropriate country code (listed above)
   6.  Wait as the update program proceeds with the update. Progress  messages confirming the language selected and indicating that the update is in  progress will be present for about 15 seconds at which stage the machine will reset  and continue with a normal power-On sequence.
10.  Successful completion is indicated by a code 00. If any other code is  displayed or no code is seen at all after a couple of minutes, then refer to the Table  below, for a Problem description.
11.  Power-off and change the memory write protect jumper (system board) to the disable position
12.  Power-On the machine

Flash Update Completion Codes 

0 Successful Flash update
1 Machine type not recognized
2 Flash is write protected (jumper)
3 Unrecognized Flash type
4 Requested Flash image file not found (US or NLS)
5 Error reading the flash image
6 VPD structure not found in image file (only in PC 700 Series)
7 Error in image file - either the checksum is bad or the Build ID is invalid
8 Error reading the Flash when /N parameter used

BIOS-Update Procedure PC 360-S150 Type 6598 or Server 315-8638 only 

1.  Power-off the computer.
2.  Insert the flash diskette into drive A.
3.  Power-on the computer.
4.  When the Update Utility appears, select your country/keyboard, then press Enter.
5.  If the computer serial number was previously recorded, the serial number is displayed with the  option to update it. Press Y to update the serial number.
6.  Type the 7-digit serial number of the computer you are servicing, then press Enter
7.  When prompted, press any key to reboot.
8.  After you hear 1 long and 2 short beeps, power-off the computer.
9.  Move the system board Flash/BIOS jumper from pins 17-18 to pins 16-17.
10.  Remove the flash diskette from drive A.
11.  Power-on the computer.
12.  Wait for the 'POST Startup Error' screen to appear, then power-off the computer.
13.  Move the system board Flash/BIOS jumper from pins 16-17 to pins 17-18.
14.  Power-on the computer.
15.  A 163 error code will appear and instructions to reset the time and date. Do so, then check the Product Data  pull down and verify the BIOS has been updated to the latest level.
16.  Press Esc and select Save to file the changes.
17.  Follow the instructions to exit the program.

1.  Power-off the computer
2.  Move the jumper from pins 23-24 to 22-23
3.  Insert the Upgrade Diskette  into the drive A
4.  Power-on the computer and listen to the speaker. You should hear beeps in the following sequence.

     (The monitor remains blank during this procedure.)

   1.  After the computer is powered-on, it beeps once. This beep marks the beginning of the POST.
   2.  After a short delay (less than 10 seconds), the computer beeps again. This marks the beginning of the  recovery process. The recovery code is being copied into the flash component.
   3.  After about 30 seconds, the computer beeps twice, marking the end of the recovery process. Wait until the diskette drive in-use LED   goes out.

5.  Power-off the computer and move the jumper from pins 22-23 to 23-24
6.  Leave the upgrade diskette in the diskette drive and power-on the computer.
7.  Retry the original upgrade procedure.
