What BIOS flasher?

Mobo1 - mobo with problem
Mobo2 - mobo for hotswap
FU1 - official flash utility for Mobo1
FU2 - official flash utility for Mobo2

At first i'm try FU2 on Mobo2 with command line key to prevent check BIOS version. If it doesn't work, then i'm try other flash utility (or other version FU2).

It means I need to type switch that is telling flash utility to skip checking BIOS version. Can u tell me what is proper switch for AUDOS.exe for Asus boards? On official AMI AFUDOS (downloaded from ami.com) i got -x switch for this action, but it doesn`t work with asus MOBOs I tried. It accepting only: afudos /iROMfilename.
Any expirienses with ASUS?

P.S. I tried to flash ASUS P5KC BIOS on ASUS P5LD2-X/GBH. (both using same eproms)

Afudos (Asus version) switches:

afudos /i<ROM filename> [/o<save ROM filename>] [/n] [/p[b][n][c]] 
[/r<registry_path>] [/s] [/k[N]] [/q] [/h] 
 
 
/n - don't check ROM ID 
/pbnc - 
b - Program Boot Block 
n - Program NVRAM 
c - Destroy System CMOS 
/r - registry path to store result of operation 
(only for Windows version) 
/k - Program all non-critical block only 
/kN - Program N'th non-critical block only 
(Example: k0/k1/k3 upto k7) 
/c - Skip non-critical blocks 
/s - leave signature in BIOS 
/q - silent execution 
/h - print help 
/t - Display ROM ID string 
/c - Program Main Bios and all Non-critical blocks 
/cN - Program Main Bios and N'th Non-critical block 
(from c0 up to c7) 
/d - Compare ROM file (skips flashing) 
/u<filename> -Display ROM ID

If switches doesn't work, then engineer version needed (afudos229ES, for example).

AFUDOS downloaded from ASUS.comdidn`t work with /n switch.
Then, I downloaded afudos229ES (version 1.9) and it worked immediately
So, for other users that have same problem this is way for flashing MOBO BIOS that are using AMI BIOS:
I found afudos229ES by simple googling and take first what come in list of sites. Then use this pattern:
afudos /i /n

Maco, thanks again for your prompt help:)
