Bad Bios Flash or?

I tried the asus liveupdate on a A7V600-x and got checksum error...

I didn't read enough in the manual to do a proper recovery and had to shut
down for the night...

Now I'we read the instruction and prepared for a manual flash from disk..
But, the thing will not boot... I get long-short continous beeps and no
indication on screen..
Something is wrong but what?

Tried clearing cmos a fiew times, but to no help..

regards
ottar t
