Boot Display with Errors1HChapter 5 explains troubleshooting the computer and bus expander using self-test errors dis-played on the monitor or LEDs.Booting From The SRMPlacing bootable ass on sector oriented devices is fairly straight forward. On LIF devices anas file must be created, and on SDF and HP-UX devices a boot area must be created. For theSRN1, ass to be booted must be placed in system files in the directory /SYSTEMS.Because the SRM is a shared resource there are some unavoidable and peculiar behaviors thatcan be exhibited if the /SYSTEMS directory changes while the Boot ROM is scanning it. Duringthe scanning or booting process, the order of the directory can be re-arranged, as files canbe deleted, or added. This means that the Boot ROM may show an as that does not existanyrnore, may not show an as that does exist, or may never show an as that has always beenthere.If an as that does not exist is chosen to be booted, the Boot ROM will stop with the error NOTFOUND. A reset is required to try again.As long as the /SYSTEMS directory is stable, which is usually the case, everything will work asexpected.Boot Rom Functions 101Artisan Technology Group - Quality Instrumentation ...
