I still don't know if you have a floppy drive or not. This Award Bios tool should give you full access to the bios. If you are still unable to flash or experiencing problems RMA the motherboard and explain to them what happened, I'm sure you're not the first to use the wrong bios ROM. Use these instructions at your own RISK!

Method# 1

Format to FAT or FAT32

2. After making bootable floppy, copy BIOS.BIN and awdflash to disk.
3. Reboot into the bios and make sure removable drive is first then restore bios setup defaults.
4. Reboot to floopy and when you get the a:\prompt, type awdflash. Inside the Award tool just follow the instructions, you will have to enter the correct path to the ROM as well. a:\BIOS.BIN

Download: Need To Flash Your BIOS On A PC With No 1.44, (click on 1.44 and save "FLASHCD.ISO" to desktop, if its in a archive extract it)
You will need an ISO application, UltraISO, MagicISO, etc; Use the ISO software to open FLASHCD.ISO. Now drag awdflash and BIOS.BIN into FLASHCD.ISO and "Save" If you double-click on FLASHCD.ISO you should see awdflash and BIOS.BIN if you followed the procedure correctly. Now burn FLASHCD.ISO to a CD. It must be burned as a CD image or it will not load on boot.
Boot into the bios and make sure CDROM is first boot. Restore bios setup defaults before flashing bios, usually F5. Put the CD in with your bios update and hit F10 to save bios setting and reboot.
When the CD autoruns you will come to a screen with some info telling you where your files are, example:
a:\FLASHCD
r:\awdflash, BIOS.BIN, etc;
Just remember your flashing tools will be on r:\, click continue to go to the next screen. Now you have to change the drive letter, at the a:\prompt type "r:" without the quotes and press enter, your drive letter should be "r" now.
Type awdflash and press enter, this will open the Award tool. Enter the path to the ROM and follow the instruction. r:\BIOS.BIN
When the flash is complete it will let you know, do not touch anything during this process or you'll be sorry. When prompted to reboot, do so and boot back into the bios. Shut the computer down by PSU power switch and unplug the PSU. Remove CMOS battery and discharge the motherboard by holding in the power button while touching the chassis for approx 30 sec. Re-install battery and post. Don't forget to re-apply your settings.
