Hi guys, I' m not sure this is the proper thread. I need help to recover from an update of bios Ami P01-A01 replaced with P01-B0 that doesn' t function. The Pc don' t boot, the screen is black. I don' t seen the led of activity for cd-dvd or pen-drive. The official recovery procedure with amiboot.rom ( that I' ve saved on pen-drive ) doesn' t function at all. The pc is Packard Bell iXtreme X7610it ( inside is Acer Aspire M5720 ). I think that the boot-block isn' t running at start. Any tips ?? Thx.
