What you are surely seeing is the PXE firmware banner displaying its PXE version compliance: v2.0 or v2.1. The PXE firmware is made by Intel and you can read "Intel" in that screen message but that tells nothing about your NIC "real" manufacturer.
I'd try to get the motherboard information and from there you can find the installed NIC alternatively you can also try installing your OS with Serva surelly you'll face the same problem (missing NIC driver) but in Serva's case you can open a console
and find the NIC data by looking at the log file
x:\Windows\inf\setupapi.app.log
there you can see something like
>>> [DIF_SELECTBESTCOMPATDRV -PCI\VEN_10B7&DEV_9200&SUBSYS_010D1028&REV_78\4&19FD8D60]
>>> Section start 2012/04/25 12:42:59.281

<<< Section end 2012/04/25 12:42:59.296
<<< [Exit status: FAILURE(0xe0000228)]
This part of the log describes a NIC with a missing driver you can also see its VEN_10B7&DEV_9200
that means VEN=10B7 DEV=9200 those numbers identify the NIC; google them and find your NIC drivers.
Please remember when dealing with "integrated" NICs is never a good idea looking for drivers on NIC manufacturer websites try the "Integrator" website instead. Motherboard and Notebook manufacturers many times use NICs with subtle differences that require their special drivers (I'm related to Serva development)
Look at the manual for the mainboard. – qasdfdsaq – 2015-10-26T12:31:28.540
