Below is a link for the downloads for the PE2400 running windows 2003 and NT4. It's a good idea to update the system bios and the ESM (embedded server management) firmware to the latest. Then make the bootable disks to upgrade the PERC firmware to 2.71 and 2.8 and put them aside. Within NT4, unzip the NT4 driver file and update the PERC driver to version 2.8, bring the server down, update the PERC firmware first to 2.71 then to 2.8. Reboot the server. When you get ready to upgrade to 2003, download the 2.8 version driver for windows 2003. Unzip the driver file and there will be a readme file with instructions. Basically, there is a batch file for the PERC driver to run in NT4 before you load the windows 2003 disk to upgrade the OS.
I am going nuts! I have an integrated PERC 2/si and it won't upgrade to 2.8, it seems to be stuck at 2.7-1. I try to run the update from the bootable floppies and when I attempt the update it tells me it cannot find PRC2si01.ufi on the floppy. The version on the floppies is PERC201.ufi (I may have them switched here).
I tried like a nutcase to rename the files on the disks to what it was looking for, but it ended up telling me that it was not a compatible image.
Please help. I have installed array manager, but cannot see anything but the regular scsi.
