The drivers is support for acer travelmate p453-m, include windows 7 32-bit drivers and windows 7 64-bit drivers. i did not list the bios because it is not for end user but for advance user.. The driver for win7 32 bit will depend on the processor. there's a model of that laptop that comes with a celeron n2820 processor, and if it's your case, unfortunately there's no driver for win7 32 bit, only for 64 bit.. We don't have any change log information yet for version 20.60.0 of intel pro/wireless and wifi link drivers win7 32-bit.sometimes publishers take a little while to make this information available, so please check back in a few days to see if it has been updated..
