  The only PERCs validated for the 1800 are the PERC 4/SC and DC. Both of them are SCSi controllers. PERC 5 and higher are SAS/SATA controllers. The PERC 5 and 6 controllers are x8 PCIe cards. The 1800 has one x8 PCIe slot, so in theory a PERC 5 or 6 should work in the system, but we have not validated them to work. I would suggest searching online to find out if anyone has tested the configuration. Thanks
I recently acquired a PowerEdge 1800 box.  No hard drives so no operating system.  Contains: a suci card attached to a tapedrive, a cd drive, and a floppy drive.  Ihave installed four 2 terabits drives attached to the sata raid card.  Disabled the suci array in the bios. Removedthe suci card & disconnected the tape drive from the power supply.  Installed two 2.8 gig dual processors.  Start the system and:  Bios utility yields: “No Int 13 Drives to support” No logical drives found, “BIOS not installed” The Bios lists the threedrives installed. But when I cont A the config array it says no drives found.   Configuring only as a home server but with possibility some familysupport. More.   What operating system when Iget past these setup problems???
