Good finding. It needs more testing on various bd. Another expected block which could have occured is resolved. Thanks.
Hopefully it will work for others, I really only did it to see if it could be done. I checked the info using the SLIC Dump tool as well as in DXDiag and both showed the modified date.
Not working on ASUS M2N-MX SE PLUS board I followed the steps; found out that the date was specified clearly and only at one spot for the smbios (06.BIN) module. Edited it using HexEdit XVI32 (most recent) BUT could not re-integrate the edited bin into the .rom file with the error message: this is not editable module!!!!! I have bios version: 0602 for that board, released at the end of 2008
I've just had a look at this BIOS and had no problems replacing modules, in this case though I found the BIOS date information in the 1B module. The 06 module just had a copy of the copyright date in it. The date which is in the BIOS is 10/29/08 so look out for 3 instances for the date in that format and one where it shows as 102908. I don't know what could be causing your problem as it didn't happen to me. I haven't been able to mod an AWARD BIOS date but there was a thread on this board asking about it.
Thanks Technoboots. I have extracted the 1B module and went through it to see the changes and it is terrific. I am puzzled why the MMtools version I have (3.19) is not allowing me replace the modules. My mmtools is being used in win7; wonder if I should use it in xp. But can't see why xp would make any difference. However, I do not have any other AMI bios to play with. I am planning on downloading some .rom files from net and see if I can make sense of this marvelous lil program. Are you using version 3.19 or is it some version? Anyways, thank you much for your helping hand.
