Large User IDs and Group IDs

In the Solaris 2.5.1 release, the limit on User ID and Group ID values has been raised to 2147483647, or the maximum value of a signed integer. The nobody user and group (60001) and the noaccess user and group (60002) retain the same UIDs and GIDs as previous Solaris 2.x releases. Sun recommends that you keep UIDs and GIDs under 60000 because there are interoperability issues and limitations with previous Solaris releases and products.

See Chapter 2, "Large User and Group IDs," for more information on this change, including limitations and restrictions. Or, see the following man pages:

tar(1)
pax(1)
edquota(1)
cpio(1)

login(1)
passwd(4)
group(4)

KCMS Calibrator Tool

The Kodak Color Management System (KCMS) Calibrator Tool provides adjustments for accurate color representation to scanners, color monitors, and other output devices. The Solaris 2.5.1 release includes a loadable driver module (in the SUNWkcspg package) for the X-Rite DTP92 Incident Colorimeter. The driver supports the X-Rite colorimeter, which connects to the serial port to obtain color measurement data.

This information is supplemental to the KCMS Calibrator Tool Loadable Interface Guide. See the Solaris 2.5.1 Software Developers Kit: Release Notes for an updated chapter that describes new procedures for adding and removing color calibration modules to the system configuration file, OWconfig.

PowerPC: System Administration

PowerPC: System Administration for the PowerPC System

Administering PowerPC systems differs in some ways from SPARC and x86 systems. Because the PowerPC system runs Open Firmware (OF) or Virtual Open Firmware (VOF), booting the system and adding a disk is different. The VOF has commands and configurable variables--similar to a SPARC System's PROM monitor-- that are used to either display or reset the way the system behaves before the operating system is loaded. Disk management is slightly different on a PowerPC system.

See Chapter 3, Chapter 4, and Chapter 5 for information on administration differences between SPARC, x86, and PowerPC systems; concepts and procedures for booting a PowerPC System; and procedures for adding a disk on a PowerPC system.

Supplemental Documentation
