I just got a new acer revocenter, with intel atom d525 in it. When i boot it up there was no options to get to the bios setting. So I am trying to flash the bios.

I created a bootable disk with iflash2.exe and the bios file. Ran this command in dos on the bootable usb stick iflash2 /pf . however i got the following message.

IFLASH2 version 2.5 - build 064

Port Mapper Table Signature not found

how can i resolve this and flash my bios?

i just put the bio on a flash drive and hit F7 on boot and the BIOS started to update itself. According to the README of the bios update Intel Mainboards from 2009 onwards should support this method.
