Bad P6t BIOS Flash

Hi People =)

My damn problem is in the title..
Having wanted to flash my bios with the asus bios flash utility, my computer won't work anymore.
The process went along the 2 first steps, deleting the previous and copying the new bios, but failed at doing the last one (verifying i think).
Now, when i powerup, NOTHING appears on screen. Only fans are working.

I tried to take away the cmos battery, and change the jumper. But it resulted in nothing.

I tried to put on a usb key (i have no floppy) the .ROM bios, naming it AMIBOOT.ROM as explained on some forums, but nothing seems to happen.
I saw on asus help that with asus crashfree software, when inserting the dvd support, the software would find the bios and flash the corrupted one. The problem is i don't have this dvd (I moved from france to norway so i took the minimum ^^) so i cannot test.

Questions :
Do you suggest any other try ?
Should I try with a floppy disk instead of USB key (formatted fat 32) ?
IF having to replace my BIOS ship : Where is it on my board ? How to extract it ? Where to buy a new one ?

I hope you will be able to answer me, and wish you a happy day.
For the one who would say that i was a dumbass to flash with a windows utility, i would answer that you don't expect a leader in mainboard design to create such a stupid software without thinking it works at least 99% of the time ^^

see you =)
