the BOOT CODE is read into the computer memory. After this point, the system "knows"
where each partition is, and what operating system it contains.
Please note, that whenever running the partition utility SASIXUxx, BE SURE YOU HAVE BACKED UP
ANYTHING ON THE HARD DISK YOU MAY WANT TO HAVE SAVED, as repartitioning may cause you to
loose any and all data on the hard disk unit. This is especially true if you are changing partition
sizes. When the software is properly set up, you can use any system disk to load or backup the
hard disk. Although the hard disk units are very reliable it is important to back up all data on the
disk at frequent intervals so if something goes wrong you can load it back in. Ever lose the data
on a 100K disk? Just think of losing 15 or 33 Megs! It's rare indeed, but could happen.
We will now take a look at the partition program, SASIXtJxx.COM, which runs under CP/M, and explain
how to use it. Please note the unit is already set up for the default conditions and partitions
as shown on the screen examples. If you leave the drive as shipped to you, you will be all set up
and ready to run with the default partitions and parameters. Partitions are already FORMATted
under CP/M and INITialized under HDOS. If you want to use the 'standard' partitions and use the
unit as shipped, you can skip the partition program and skip the INIT and FORMATting. Simply set
up the system, SYSGEN, and go.
