Bios Update Gone Bad Options

[xarvox]

I tryed upgrading the bios (to get bigger harddrive support (200gb drive installed, only a couple of a few hundred mb partitions showed up)
The bios upgrade went along fine, no errors or odd behaviors..

but after shutdown it wont come back on..

the green lights on the front turn on, then off again a few times before red/green leds start blinking.
i tryed the "rescue dvd" that i got with my xbox, but with no luck..
it wont power on the remote, nor outputting anything to the tv..

I just bought the xbox used, have no idea about the platform nor my specifications..
Can anyone help?

or is the trashcan the next home for my xbox?
