Welcome to SysOpt!
It sounds like you flashed your board with the wrong BIOS image.
Looking at ASUS's site, there are two similarly named boards - the CUSL2 and CUSL2-C, so maybe you got the wrong one. The Wim's BIOS FAQ (http://www.wimsbios.com/index.htm?/HTML1/faq.html) has some advice (look at Q9), as does BadFlash (http://www.badflash.com). Good luck.

I would disconnect any usb devices during the flash process just to be sure. There can be No power interruptions during the procedure.
If you saved the old bios , then use it to restore the boot block. If not find the correct .bin for your board.
Next, follow the advice in this article for recovery...

*If you find during the recovery procedure no floppy drive activity , you wont be able to recover. Then, www.badflash.com is your only hope , besides a hotswap with another exact mobo.
