[LinuxBIOS] How to ID flash chip type from software?

[Anton Borisov]

Hello. 
	There is a tricky case - I can't see which exactly flash chip installed in system. flashrom from v2161 was unable to identify it too. I found an interesting site - http://ctflasher.sourceforge.net - however this tool doesn't have bios-flasher yet.
