A Biosflash went wrong (GE-7vkmp)

[IB]

I NEED your help and support just now I happened to flash my new motherboard with a faulty rom-file and now nothing happen except a lot of beeps! - 8 - I think...
I´ve read about the amiboot.rom - method but nothing happen - obviously the bootblock recovery feature does not make it.

It´s a Gigabyte GA-7vkmp motherboard with a soldred bioschips...

There is a combination of keys to press when turning on the computer with the file amiboot.rom in the floppy, for some models it´s Ctrl+Home or Ctrl+Inset.....but none of them works with this mobo..

Do we have any mobo-technician here who can help me with this issue?
TIA

Edit: The headline says it´s GE-7vkmp..of course..it´s misspelled, should be GA-7vkmp model
