[flashrom] How to obtain a BIOS image from another computer use flashrom？

[zy]

Hi，
   I'm a student from China and I've been learning flashrom，So I would like to know whether the flashrom can support extracting BIOS firmware images under Windows 7/10.
   If I don't have the Internet（Just LAN），how do I remotely obtain a BIOS image from another computer use flashrom？
   Maybe my English not very well. Thank you very much.

   Looking forward to your reply.
