What to use to open old bios?

[trodas]

My Asus TXP4-X have old Award bios. I use the Asus TX97-XE in it anyway, but both bioses cannot be opened using normal Modbin version that I use for all these Award bioses, claiming that "bios is not version 6.0":

 

 

Now... witch version of Modbin is possible to use there? I need to look, if there can be unlocked TRP (precharge) settings to lower value that too slow 3... Because I don't know any MemSet equivalent that let me change the Intel 430TX ram settings

 

Anyone can suggest application that can open this bios?
