I am looking for the current firmware for Adaptec AIC-7880 Ultra/Ultra with BIOS v1.26s6, Dell 06s6

The machine is a PE 4200/single 233, I inhereted the system and cannot retrieve the service tag information. I also looked in the BIOS (F2) and did not see anything. I have update the Pheonix BIOS from A01 to A05, PERC II firmware to U.87. I would like to include this firmware update before install Win2k advanced server OS.During the firmware updates, I started to see this message " No SCSI boot device found" and "SCSI BIOS not installed" Can anyone point me inthe right directon?

Thanks for the help
