bios rom file or backup

[audino]

hi,
im trying to backup my bios to be able to edit it...
but im using vista 64 and unable to backup it with winpflash, therefor i downloaded the bios and try that one. the problem is there is no rom file, is there a way to get a rom file of the actual bios for the download maybe packit back or something else...
or can anyone upload a backup from his actual t61p bios?
thx a lot

ps.: the background is to unable some options in the bios
