Native p-System Hard Disc Partitions

Around 1983, the Center got p-system versions with hard disc drivers in them. (These and any other blocked device drivers are all collected into SYSTEM.CONFIG, which is managed with CONFIGURE.CODE). The p-System could now boot from hard disc partitions.

Some of the older machines at the Center (XT's, Olivetti's) still have on their hard discs partitions for the p-System. By current standards they are quite small -- 5 megabytes is 10,000 blocks to the p-System, which provides a respectable amount of storage. They can be chosen for booting by using the program FDISK in DOS to change the so-called ``active'' partition. (When using the option to list the partitions, to see which to turn active, the p-System partitions will be listed as Xenix partitions.)

DOS booting can be restored, when desired, by executing the corresponding program TOOLS:FDISK.CODE and following its menu.
