choose your processor...
all were .zip files. Other places you might find .exe files, which are usually self-extractors.
.bin files are not drivers, can't be used, yes are all binary storage, used with specific programs as indicated by the front part xxxxxx.bin.
Caution, if things are working okay, it's not often advised to update BIOS; simply because it's easy to ruin it thus ruin the mobo. Read about the BIOS revision, what it's about, then decide.
Almost same caution about mobo drivers. Why need new ones? It's more often that onboard devices need good or updated drivers: video, sound, modem. Otherwise you are talking chipset drivers and the latest can be found at the mfg. website: intel, Via, SiS, etc.
I downloaded an updated driver for a Jetway 866as Ultra motherboard, and it has come down as a .bin file. I believe that this is a binary file, and am not sure how to open and execute it, so that it updates the motherboard driver. There is a BIOS upgrade as well, and I think this also is in the form of a .bin file. Could you please give me a clue on this one?
