To recap: One of our clustered 750s refuses to boot due to SYSBOOT complaining about a missing instruction emulation file: VAXEMUL.EXE. This file is not present on any of our other non-clustered VAXen. More info: After consulting the fiche, it turns out that there are four instructions that will cause this file to be loaded if they fail via OPCDEC or emulation faults: MATCHC DIVP EDITPC CRC Upon running the instruction diagnostics, MATCHC, DIVP, and EDITPC are listed and pass, but CRC is never listed. We ran diags on a working 750 on the same cluster (which reboots fine), and it doesn't report CRC either. Just for fun, we then ran the floating point diagnostics. The diags claimed that G,H-floating options were not present, but then ran such tests anyway that passed. I have looked all through our current systems, backups, and some past installation kits. They all seem to contain FPEMUL.EXE, but none contains VAXEMUL.EXE. Does anybody know what is going on here? Are the diagnostic trace messages just not complete? Is this ONE instruction (CRC) bad??? Any suggestions welcome, Jeff.
