Matt, thanks for the information on upgrading the BIOS. I'll give that
a try. The BIOS upgrade was more of an after thought when I was looking
at the drivers site for the PERC 5/i firmware update which is what I'm
mostly interested in.

I seem to notice that the newer PE1950 seems to have faster disk access
than the older one. This could just be my imagination as I don't have
any data to back it up, however it is what started my search for any
errors in dmesg which led to looking updated firmware, etc.
I figured updating the firmware might be worth a shot, but if you are
saying that those messages are purely cosmetic then I'll take your word
However, it sounds like the PERC 5/i update is "Urgent", so I probably
need to update it regardless.
In my case, how would you recommend going about it? I am able to access
the machine physically if I need to, I just don't happen to be running
any of the supported OS.
USB Floppy might work. Do you know if I can boot off a USB floppy on a
PE1950? If so, that would solve my problem.
