This is not bios think, this message is like old video card - im here boot message, im not booting from it, i just got hey im here Legacy bios start message..Tell me what options you are referring to? If it is asking for a DHCP lease, you should change the boot order in your BIOS to HDD 1st, CD-Rom 2nd and NIC 3rd
If you think Boot device list, its not helping.Take the NIC out of the boot list in BIOS.
I know, i only wonder which from that 5 options is boot screen menu, could disable it, there 2 options, timer and second options.. I dont this card know by my side, so i can say that is new of that second options..Either use the software I linked you to to disable it in windows or see if there is a keystroke combo that allows you to enter the BIOS menu on that card to disable to boot manager.

Per Intel that feature is Turned On by default .. You need to run their utility to turn it OFF
Also in your BIOS the best boot order would be: USB / ODD / HDD / NIC (if you need to boot from a network server)
