Inspiron 500m + Docking station PD01X (bios or?)

Hello to everyone.

I have an old Inspiron 500m in perfect condition, upgraded with 2 gb ram and 160 gb hdd. :)

Recently, I got a docking station PD01X.

Is there any way to use the docking station with Inspiron 500m?

Maybe loading a Latitude d500 bios (D500_A10.exe)?

Eventually, will I have the possibility to move back to the Inspiron 500m bios if I change into a d500?

Has anyone experienced changing a Latitude bios into an Inspiron?

I also noticed that, in Inspiron 500m driver page, bios is different - it's reported Dell Inspiron 600m System BIOS, A17:

@Dell: can you confirm? Maybe it's a mistake? Can I receive the last Inspiron 500m bios (I am actually mounting 500m_A08)?

Thanks!
