My understanding is that a BIOS may be specific to the machine.
In the past, I've been able to find BIOS updates at manufacturer web 
sites.  This one is difficult to navigate, but the closest I have been 
able to find is:

http://www.acerpanam.com/synapse/forms/portal20.cfm?website=AcerPanAm.com&siteid=7117&areaid=2&formid=3394#results

Product Line => Desktop
Aspire M3640
Search

In the list that results, I see "INT15 Driver for AMI BIOS Core" for 
Vista, but no BIOS.  It could be that I just don't know where to look.

Note: my actual machine is designated AM3641-EQ8200A
