I'm trying to do a fresh install of FreeBSD 6.1-RELEASE on a new
Dell PowerEdge 1855 blade server.  The hardware notes for 6.1 say
the Dell PERC 4/IM SCSI raid controller is supported by the amr
driver.  The problem I'm having is that the kernel on the install cd
is trying to load the mpt driver, which sees the controller and then
fails to load with a timeout error.  How do I install FreeBSD with
just the amr driver and not the mpt driver?

I don't see offhand how that could be happening in the first place. Time to ask the driver author, perhaps.
Without some information about what FreeBSD is seeing, it's impossible to say what controller you really have and why it is being detected how it is.

If you can get to the point where you can run "pciconf -l -v" (fixit shell?) you can see exactly what information FreeBSD sees to identify the device. You can then compare that to the IDs that the amr and mpt drivers latch on to. (The cvs web tree would have that, or you could try posting back that info so that someone with 6.1 could check).

It wouldn't be unheard of for Dell to have *changed* which chips they use for a PERC 4/IM; or perhaps there is a documentation error. But if the mpt driver is latching on to the device it must be because it thinks it should. If the amr driver does not recognise the device then what you are suggesting wouldn't work, even if it were possible. Unless there is a bug, then, in general, only one hardware driver will ever recognise any specific device/chip.

If it really is the mpt driver which should be loaded, then, as Lowell says, asking the driver author (or trying hardware@) would be your best bet.

Did you try google for "Dell 1855 Freebsd"?
