Acer Travelmate 8481TG

Hi, I hope someone can help me. I am trying to replace the HDD in my Acer Travelmate 8481TG with an OCZ Vector SSD however for some reason the SSD is not being detected by the BIOS. It was recommended as a possible solution that a modified BIOS could help by having access to all the menus/settings. I would really appreciate it if someone could offer a modified BIOS for my Acer Travelmate 8481TG.

Thanks in advance.
Declan.
