When I'm loading an OS I only use PS2 mouse and keyboard.

 

BIOS is actually a primative OS and it appears to have sufficient drivers to let your USB keyboard and mouse work while the BIOS "OS" is in charge.  Those drivers don't carry forward, however, to the next step.

 

When you are loading W7Pro you are running off a limited set of drivers on the bootable part of the DVD, before the fuller install of the drivers for the OS drive (both the ones that will be used based on what the installer sees and ones that are archived for possible later use) are loaded.  Whatever chipset you might have for USB functionality on that workstation appears to not have drivers for the initial boot OS from the DVD (which get added to by the install process, or afterwards by yourself from whatever source works).  Think of this as 4 layers of drivers..... BIOS, CD Boot, W7OS after full load from DVD, and finally after you have done added fine tuning.

 

Ergo, my choice to always build up using PS2 mouse and keyboard.......
