Yes, it turns out I do have a PERC/2 I should have checked that more
closely. But that wasn't the problem anyway. In the system setup I can
limit memory to 256 meg for "OS Setup". Once that is done I can boot
normally from the RH 6.0 CD and everything is fine, I don't need the
patches or boot images from ftp.megatrends.com. Everything installed
properly, the drives are striped, and I'm rebuilding an SMP aware kernel
right now.
So hopefully the next person that uses altavista to search for [ DELL
PowerEdge 6300 Megaraid linux boot PERC ] will retrieve this message and
know exactly what to do :)
Thanks Ben!

First of all, verify that you are indeed using the PERC controller and
not the PERC/2. AFAIK, there are currently no drivers for the PERC/2
controllers, although I hear the drivers may be in the works at Dell
(might be a good idea trying to contact them about it). I currently use
SMP with a Dell Poweredge that has the PERC controllers installed, and
it works very well with 2-way SMP, although the SCSI bandwidth with the
PERC controllers is a lot smaller.
Makes it kind of hard to sell Linux if there are no drivers for it. :-(
I've been able to detect and install the PERC controller using both Red
Hat 5.2 and Debian 2.1 or better. (Debian 2.0 doesn't work).
