Patch_SG0002122_Release_Note This release note describes patch SG0002122 to IRIX 6.2. 1.1 Supported_Hardware_Platforms This patch contains bug fixes for dual-head NEWPRESS systems. This is a system with an IP22 CPU and dual-head XL/Express graphics. 1.2 Supported_Software_Platforms This patch contains bug fixes for eoe.sw.gfx on a system running IRIX 6.2. The software cannot be installed on other configurations. 1.3 Bugs_Fixed_by_Patch_SG0002122 This patch contains fixes for the following bugs in IRIX 6.2. Bug numbers from Silicon Graphics bug tracking system are included for reference. o 383111 - Reboot hangs on 250MHz, dual-head Indigo2. (Actually, the hang occurs only for heterogeneous dual-head, i.e. a system in which the two gfx heads are different types. If the system is dual-head but with the same gfx types on each head (e.g. XL/XL), then the hang does not occur. Also, the hang occurs only when the system console is a graphics system console, i.e. when the prom(1M) environment variable console = g.) 1.4 Subsystems_Included_in_Patch_SG0002122 This patch release includes these subsystems: o patchSG0002122.eoe_sw.gfx. 1.5 Installation_Instructions Because you want to install only the patches for problems you have encountered, patch software is not installed by default. After reading the descriptions of the bugs fixed in this patch (see Section 1.3), determine the patches that meet your specific needs. - 2 - If, after reading Sections 1.1 and 1.2 of these release notes, you are unsure whether your hardware and software meet the requirements for installing a particular patch, run inst. The inst program does not allow you to install patches that are incompatible with your hardware or software. Patch software is installed like any other Silicon Graphics software product. Follow the instructions in your Software Installation Administrator's Guide to bring up the miniroot form of the software installation tools. Follow these steps to select a patch for installation: 1. At the Inst> prompt, type install patchSGxxxxxxx where xxxxxxx is the patch number. 2. Initiate the installation sequence. Type Inst> go 3. You may find that two patches have been marked as incompatible. (The installation tools reject an installation request if an incompatibility is detected.) If this occurs, you must deselect one of the patches. Inst> keep patchSGxxxxxxx where xxxxxxx is the patch number. 4. After completing the installation process, exit the inst program by typing Inst> quit 1.6 Patch_Removal_Instructions To remove a patch, use the versions remove command as you would for any other software subsystem. The removal process reinstates the original version of software unless you have specifically removed the patch history from your system. versions remove patchSGxxxxxxx - 3 - where xxxxxxx is the patch number. To keep a patch but increase your disk space, use the versions removehist command to remove the patch history. versions removehist patchSGxxxxxxx where xxxxxxx is the patch number. 1.7 Known_Problems The process of installing this patch will cause a new /unix to be created. (That's different that the usual patch installation, in which a new /unix isn't created until the system is rebooted.) This system won't be running with this new /unix, however, until it is rebooted. Until the system is rebooted, commands such as gr_osview, which depend on /unix, may not work. After installing this patch, you need to reboot the system before it will be running with the patch. When you perform this reboot, the system might hang. If that happens, simply reset the system. When it comes back up, it will be running the new /unix. (The new /unix can be rebooted without hanging.)
