Most users keep the latest version of the MPC2000’s operating system on a 3.5-inch diskette inserted into the onboard reader, so that it will automatically load as soon as the unit is powered up. But did you know that you can boot the MPC2000 without the system disk? Basically, you just copy the latest operating system onto an external SCSI drive using the MPC’s DISK menu. By powering up the SCSI hard drive first, followed by the MPC, the MPC2000 will search for the latest operating system on the floppy disk drive and if it doesn’t see one, it scans all the SCSI drives starting with SCSI ID 0. By Setting your external drive to a low SCSI ID number, the process will be a little faster than if you assign it an ID of, say, 7.
