Finally booted into userconf, disabled iop, and see:

pci2: i/o space, memory space enabled, rd/line, wr/inv ok
Intel ROB-in i960RP Microprocessor (standard I2O, interface 0x01, revision 0x02)
 at pci1 dev 10 function 1 not configured

Whereas with iop I had:

pci2: i/o space, memory space enabled, rd/line, wr/inv ok
iop0 at pci1 dev 10 function 1: I2O adapter <MegaRAID>
iop0: interrupting at irq 5
op0: configuring...
iop0: unable to retrieve HRT

The PERC BIOS doesn't mention i20 at all, it really is a PERC 2/DC..
(sees all the disks etc)

Cheers,
