Dell 2850 Raid Question

I recently bought a Dell 2850 off ebay.  Very clean unit everything powers up etc.  It came with 2x 36gb Ultra320 drives, i purchase another 2 73GB u320 drives, and only have one 73 gb in addition to the 2 36gb installed currently, It shows all the drives fine, and i was attempting to put esxi on the machine, it listed all 3 drives so i just picked one of the 36gb and installed it there, however on reboot it don't find the mbr, my question is i thought the 2860 had perc 4 raid card in it, however, i don't see any option to configure any raid.  Am i missing something, the only thing that might resemble is the LSI logic controller, but that doesn't have anythig to configure RAID unless I am missing something?  any ideas?

can you log into the RAID controller and check to see if there is an option to select boot disk?

For the PERC 4e/Di, you need to look for a CTRL-M prompt during POST to enter the configuration utility.  If you do not have that option, you must first enable it in the BIOS (F2) ... Integrated Devices, Set Embedded RAID to RAID ENABLED.

i don't have the perc4 i believe, thus my confusion, CTRL-M is the LSI Logic management
PowerEdgeTechIT ConsultantCommented:
If drives are connected to onboard connectors and you cannot enable RAID in the BIOS (under Integrated Devices), then you do not have a RAID controller (RAID key, memory, battery required to enable RAID in BIOS).  In this case, the drives will only be handled by the onboard SCSI controller.  If they are connected to an add-in PCI RAID controller card, then you should have some other BIOS option during POST ... CTRL-M if it is a Dell RAID card, CTRL-A for Adaptec (non-Dell), etc.

If by LSI Logic management you are talking about CTRL-M (not CTRL-A), then you should be able to go to Configure>View/Add to see current config, create new config.
