No, all the extra firmware will load one device at a time. So you get to see all 4 NICs load their firmware, your onboard SAS controller loads its RAID stuff, then your fibre-channel HBAs, your BIOS does its thing, and so forth and so on, not necessarily in that order, and all in serial.
One of the reasons things are done this way is that generally each device's firmware will give the operator an opportunity to modify settings as it boots, so it will ask you to hit a key or some combination of keys and then wait a number of seconds for that to happen.
If we had some fancy modifications to LinBIOS maybe you could just tell the BIOS that you want to get into the firmware options for X device and then it would take you right to it, while skipping all the waiting for input.
But, alas, we don't, so we just wait for 5 or 10 minutes while the server boots.
