Hi everyone, Portable Toshiba Satellite P200-100 (PSPBOE), MS Vista. Following a BIOS update proposed by Toshiba, the flash crashed and my notebook is dead. I know that dozens of geeks succeeded in resuscitating their dead computer thanks to many explanations, especially on this site. On power on the computer remains black with only fan spinning. I tried crisis recovery, with many combinations of phlash16.exe + bios.wph + mini.dos ; these files being written on a 1.4 diskette running on a external drive bought for this purpose. I had some partial success; with some combinations, the A: drive remains spinning for 2 minutes, but then nothing, even if I wait 10 more minutes. I got the last BIOS (srae170a.rom renamed bios.wph) from Toshiba official site. Toshiba support is not helpful. I would be very grateful if somebody could help me; I have a few questions: 1- How many times the BIOS chip can be erased and rewritten (can I go on trying)? 2- Most likely the BIOS chip is sold on the motherboard right? (I am not confident in disassembling the laptop); 3- I don’t have a backup of the previous BIOS: if someone had one by any chance. Thank you for your help.
