I got a Dell GX 260 without OS. I removed the hard-drive from my old system and set it to master and set the jumpers on the new system to slave and daisy-chained the hard drives into the new system. On boot however, I get the error PXE-E51 and PXE-M0F. I have entered BIOS to reset the hardware but there is no way that I can see to change the specs on the two hard drives.

Granted I'm reaching back several years since the last time I did so much hardware manipulation (it felt good!) but I am at a loss trying to figure out how to have the new computer boot, preferably off the drive from the old computer
