leave it on jumper free setting, and reset your CMOS by removing the battery (or if you know where the jumpers are to clear the cmos use those) put the battery back in, and see where that gets you. Basically what is happening is the computer thinks it has the old cpu in there, and since the 933 is not the old one, it is giving you this error (I think) Try clearing the CMOS and see if that gets you anywhere. If it doesn't, you may need to flash the bios.
