Hi,

I just got an D2703-A1 mainboard (mini ITX), which is a striped down version of the D2703-S1 board. I need the bios of the -S1 board on mine to use SATA and stuff, but can't get it flashed.

Here is the content of the biod update directory (-S1 board):
Code: Select all01.12.2010  15:04             4.478 A2703_S1.OMF

01.12.2010  15:04               125 M2703_S1.OMF


And this is the -A1 board:

05.10.2009  10:53               125 M2703_A1.OMF


the bioflash update tool has the following options:
Code: Select allCopyright (c) 2009 Fujitsu Technology Solutions

Usage:
BIOFLASH filename.OMF | filename.OCF | filename.ENC

 <options>
  filename.OMF   BIOS image, BIOS module or CMOS update file
  filename.OCF   Packed BIOS image update file

 <options>
  /ARCHIVE       Create archive files of BIOS and CMOS
  /AUTO          Search for a suitable BIOS OMF-file in current directory
  /CAUTO         Search for a suitable CMOS OMF-file in current directory
  /CMOS          Create a cmos archive file: Cxxxx_xx.OMF
  /INFO          Display system and BIOS information
  /NORESET       No reset after flash device is programmed
  /U             Update only if installed BIOS is out-of-date
  /Y             Answer 'YES' in advance to any prompt
  /KEY
  /KEY()         Use a specific key for encrypted files
  /NOP6          No implicit auto-update for CPU microcode patch area
  /P6            Explicit auto-update for CPU microcode patch area
  /P6()          Insert any microcode, independent of the installed CPU
  /X16MB(n)      Force bioflash.exe to move its buffers in memory n*16MB
                 Avoid collisions with RAMDRIVE, LAN remote boot, etc.
  /MODULE(X,YY)  Module update  X=PtlClass(ascii) YY=AbgClass(hex)
  /NOAPI         Use the Bioflash plug-in file instead of BIOS API



The .OCF files are the main BIOS update files which contain everything.

Specifying the files from the -S1 board on my -A1 board just gives me an error saying wrong hardware.

Changing the -S1 files (D2703_S1.OCF) in the header (on 0x00030) to say its for the A1 results in checksum error, since I don't know where the crc byte sits.

Could someone please help me with this mess? ;)

I uploaded both bioses on my webserver, you can get them here: LINK


Thanks in advance.
