Server 2003 on PowerEdge 2300 - Intel 82371AB/EB chipset

​ I have just installed Windows Server 2003 Standard Ed on a PowerEdge 2300 that was running NT4.0 server - all went well except I have one item in Device Manager that shows that the driver is wrong or it's not working properly - Under Universal Serial Bus controllers I have an "!" for Intel(R) 82371AB/EB PCI to USB Universal Host Controller and the device status says "Your computer's system firmware does not include enought information to properly configure and use this device. To use this device, contact your computer manufacturer to obtain a firmware or BIOS update (code 35)". The driver file details have 4 drivers listed and they are all "signed" with the green checkmark - usbhub.sys, usbport.sys, usbuhci.sys, and usbui.dll. ​

​ ​

​ I downloaded the BIOS v. A15 from Dell support and have contacted Dell Tech support via on-line chat and they gave me the ESM firmware to download. I followed their instructions and downloaded both and still have "!" - any ideas? ​
