Go into the bios and disable ACPI (select off/disabled from S3 or S1 etc), now it will go past post and allow you to re-flash original. Let me know if this helped.
I do not have an answer for you with regard to fijitsu....it is not my job to do that...this is your job to find out how to flash your bios.....sorry, but I have no answers for you....I don't have your machine.
I need the report....that is the only way to make sure the bios modification is tailored to your computer
