P5 N-E Sli and BIOS;

Bonjour,

i was with BIOS 0505, all was good, but i have upgraded in 0901, i know,
i am silly to try that. :-(
I have 13 USB peripherals (mouse, keyboard and some GoFlight and CH
Products flight yoke and pro pedals), when i was in BIOS 0505, when i
reboot until search drives 5' passed, now in BIOS 0901, 17 seconds
passed between reboot and search drives. :-(
I have tried to downgrade my BIOS in 0505 but with ASUS update
(V7.09.02) i have the following error message: "this BIOS image can't be
use with this motherboard; eeprom type is incompatible. :-(
When i use DOS Awdflash, i have a message: you can't downgrade the BIOS
with this file, but, the 0505 file is right, i have already use it.
And when i want to use AFUDOS.exe, it demand a rom file, but on ASUS web
site, i don't have seen any rom file for the P5 N-E sli.
Then, how to coming back in 0505 Bios ?.
Help me please. :-)))
